# Displaying long division manually with some caveats [closed]

Due to odd circumstances, I need to present long division manually (in math mode). That is, without using a macro. Moreover, I cannot use \multicolumn or \cline. Normally, I would do:

$\begin{array}{cccc} & 0. & 7 & 5 \\ \cline{2-4} \multicolumn{1}{c|}{4} & 3. & 0 & 0 \ & 2. & 8 & \\ \cline{2-3} & & 2 & 0 \ & & 2 & 0 \\ \cline{3-4} & & & 0 \end{array}$


but is there a way to obtain similar results without \multicolumn or \cline? I'm also open to options using asymptote.

I'm not looking for a generator as they don't insert a 0 when the divisor does not go into the dividend. I'd like a manual way of doing this that looks half-way decent.

This question appears to be off-topic. The users who voted to close gave this specific reason:

• "This question does not fall within the scope of TeX, LaTeX or related typesetting systems as defined in the help center." – egreg, Peter Jansson, mafp, Jubobs, Claudio Fiandrino
If this question can be reworded to fit the rules in the help center, please edit the question.

@Close Voters: I would say just an edit is needed. A solution for this that works in LaTeX would (likely) work with MathJax as well. – Sean Allred Dec 20 '13 at 5:25
MathJax questions are generally considered off topic, but this one is a duplicate, anyway: Is there a long division macro? – Alan Munn Dec 20 '13 at 5:28
The duplicate questions get TeX answers (this is a TeX forum) but for something that works with mathjax you could look at dpcarlisle.blogspot.co.uk/2012/10/mathml-long-division.html – David Carlisle Dec 20 '13 at 11:03
Answer's to the question @AlanMunn points to need not, and in fact are not, answers to this question. I regard Mathjax markup questions as on topic for this site (as opposed to ones about installation, or problems with this or that browser), so I've voted to reopen. – Charles Stewart Dec 20 '13 at 17:23
Cf. meta.tex.stackexchange.com/questions/272/… - my opinion is pretty much what Martin Scharrer said there. – Charles Stewart Dec 20 '13 at 17:26
