I would create such a similar thing:

enter image description here

I tried using polynom package but the operation I'm doing aren't the common operation because I'm working on galois field so I don't want the result that polynom package give me. How can I create that image ?

  • What would you be giving as an input? – T. Verron Nov 27 '12 at 22:56
  • I gave \polylongdiv{}{} – Mazzy Nov 27 '12 at 22:59
  • I mean... Would you give only the polynomials x^3 + x^2 + 1 and x+1, or the full computation, possibly with alignment characters? – T. Verron Nov 27 '12 at 23:04
  • I would have the full computation with alignment characters... – Mazzy Nov 27 '12 at 23:05

    @Mazzy TeX is not good in higher algebra, I'm afraid. :) – egreg Nov 27 '12 at 23:30

You could use an array in conjunction with the booktabs package:

Notes:

  • This example was more focused on the alignment issues and not the drawing issues, so there us probably much room for improvent related to the drawing portion.

Code:

\documentclass{article}
\usepackage{amsmath}
\usepackage{booktabs}

\newcommand*{\Ph}{\hphantom{{}+{}}}%

\begin{document}
$\begin{array}{r  l@{} l@{} l@{} l@{} l@{}}
                                    &x^4 &{}+ 1  \\
\cmidrule{2-6}
\multicolumn{1}{r |}{x^3 + x^2 + 1} &x^4 &        &{}+ x^2 &{}+ x &{}+ 1 \\
                                    &x^4 &{}+ x^3 &        &{}+ x & \\
\cmidrule{2-5}
                                    &    &\Ph x^3 &{}+ x^2 &      &{}+1\\
                                    &    &\Ph x^3 &{}+ x^2 &      &{}+1\\
\cmidrule(l{10pt}){3-6}
\end{array}$
\end{document}
