-Does long division. The dividend must be a positive decimal number and the divisor must be a positive integer. Correctly handles repeating decimals, putting a bar over the repeated part of the decimal. Handles dividends up to 20 digits long gracefully (though the typeset result will take up about a page) and dividends between 20 and 60 digits long slightly less gracefully.
-
-Defines macros \longdivision and \intlongdivision. Each takes two arguments, a dividend and divisor. \longdivision keeps dividing until the remainder is zero, or it encounters a repeated remainder. \longdivision stops when the dividend stops (though the dividend doesn't have to be an integer).
-
-\longdivision also has an optional argument "max_extra_digits". If max_extra_digits is 0, the behavior is like \intlongdivision, whereas if max_extra_digits is greater than 60, the behavior is the same as \longdivision without the optional argument. In general, \longdivision won't add more than "max_extra_digits"  It might be prudent to use this optional argument if you are computing, say, 1/97 which has a 96 digit period (\longdivision will stop anyways to avoid overfull boxes, but the result might not be ideal).
-
-\intlongdivision behaves similarly to the \longdiv command defined in longdiv.tex, though I think \intlongdivision looks better, and it can handle much larger dividends and divisors (the dividend is only constrained by the size of the page, and the divisor can be up to 8 digits long).
-
-Please email me if you discover any bugs or have any feature requests.

+ \maketitle
+
+The \longdivname\ package defines two main commands: |\longdivision| and |\intlongdivision|. The usage for both is |\longdivision[|\meta{options}|]|\marg{dividend}\marg{divisor}. The difference is that |\longdivision| divides until the remainders repeat or the quotient has too many digits to fit the page, whereas |\intlongdivision| does integer division and leaves the remainder. The command |\longdivisionkeys|\marg{options} is also defined to set default options. At most 20 division steps worth of work will be displayed and at most 60 digits worth of division output will be produced. Thanks to Mike Jenck, Cameron McLeman, and Yu-Tsung Tai for emailing me with bug reports and feature requests.
+
+Here is an example usage:
+
+\begin{tcblisting}{sidebyside}
+\longdivision{100}{22}
+\quad
+\intlongdivision{100}{22}
+\end{tcblisting}
+
+These commands have several key-value options:
+
+\begin{key}{max extra digits = \meta{nonnegative integer}}
+This key determines the maximum amount of ``extra'' zeroes to add to the end of the dividend in the process of division -- if the quotient has more digits before it repeats, the division will just stop. This is only an option for |\longdivision|, the command |\intlongdivision|\marg{dividend}\marg{divisor} is equivalent to |\longdivision[max extra digits=0]|\marg{dividend}\marg{divisor}. For brevity, this option has the short form where just the value is provided: |\longdivision[2]|\marg{dividend}\marg{divisor} is the same as |\longdivision[max extra digits=2]|\marg{dividend}\marg{divisor}.
+
+\begin{tcblisting}{}
+\longdivision[max extra digits = 2]{10.0}{7} \quad
+\longdivision[1]{10.0}{7}
+\end{tcblisting}
+\end{key}
+
+
+\begin{key}{stage = \meta{nonnegative integer}}
+This controls how many steps worth of division to do. Thanks to Cam McLeman for suggesting this feature.
+\begin{tcblisting}{}
+\longdivision[stage=0]{1}{7} \quad
+\longdivision[stage=1]{1}{7} \quad
+\longdivision[stage=2]{1}{7} \quad
+\longdivision[stage=3]{1}{7} \quad
+\longdivision[stage=4]{1}{7} \quad
+\longdivision[stage=5]{1}{7} \quad
+\longdivision[stage=6]{1}{7}
+\end{tcblisting}
+\end{key}
+
+\begin{key}{style = \meta{style}}
+Control the style for typesetting the result of long division. The options are |default|, |standard|, |tikz|, or |german|. The option |default| is the same as |tikz| if \tikzname\ is loaded and otherwise is the same as |standard|. You probably should load \tikzname\ because the \tikzname\ version looks significantly better. If you use this option, you'll probably want to set the style once and for all in your preamble with |\longdivisionkeys{style=|\meta{style}|}|.
+\begin{tcblisting}{}
+\intlongdivision[style = tikz    ]{100.0}{13} \quad
+\intlongdivision[style = standard]{100.0}{13} \quad
+\intlongdivision[style = german  ]{100.0}{13}
+\end{tcblisting}
+You can define your own typesetting style by saying |\longdiv_define_style:nn|\marg{style name}\marg{code}. This can use the commands |\longdivdividend| which contains the dividend, |\longdivdivisor| which contains the divisor, |\longdivquotient| which contains the quotient, and |\longdivwork:| which contains the |division work|.  For instance, a simplified version of the |german| style is:
+\begin{tcblisting}{}
+\longdivdefinestyle{my style}{%
+     \begin{tabular}{@{}l@{}}
+    \longdivdividend  : \, \longdivdivisor \,  = \longdivquotient \\
+    \longdivwork
+    \end{tabular}
+}
+\longdivision[style = my style]{2}{3}
+\end{tcblisting}
+Send me an email if you cannot figure out how to make a style to your liking.
+\end{key}
+
+\begin{key}{repeating decimal style = \meta{style}}
+Control the way that repeating decimals are typeset. The options are |overline|, |dots|, |dots all|, |parentheses|, or |none|. The default is |overline|. The |parentheses| style creates ugly spacing problems and the |dots| style is insufficiently visible, so the |overline| style is the best. If you use this option, you'll probably want to set the style once and for all in your preamble with |\longdivisionkeys{recurring decimal style=|\meta{style}|}| |\longdivisionkeys{style=|\meta{style}|}|. Like the |style| key, this is designed to be extensible. However, the process of creating new |repeating decimal style|s is a bit involved. Send me an email if you want a new |repeating decimal style|.
+\begin{tcblisting}{}
+\longdivision[repeating decimal style = overline   ]{5.3}{37} \quad
+\longdivision[repeating decimal style = dots       ]{5.3}{37} \quad
+\longdivision[repeating decimal style = dots all   ]{5.3}{37} \quad
+\longdivision[repeating decimal style = parentheses]{5.3}{37} \quad
+\longdivision[repeating decimal style = none       ]{5.3}{37}
+\end{tcblisting}
+\end{key}
