This has been my solution:

(Sorry, for the sub-optimal alignment.)

$(x^3+2x+1) : (x-a) \rightarrow x^2$
$-[(x-a)\cdot x^2] = -x^3+ax^2$
$\text{+________________________}$
$ax^2 + 2x +1 / : (x-a) \rightarrow ax$
$-[(x-a)\cdot ax] = -ax^2+a^2x$
$\text{+________________________}$
$2x+a^2x+1 / :(x-a) \rightarrow (2+a^2)$
$-[(x-a)\cdot (2+a^2)] = -2x+2a-a^2x+a^3$
$\text{+________________________}$
$2a+a^3+1$

Here's some examples from Tex StackExchange:

and from the Tex Users Group:

and doing it with MathJax from StackExchange again:

Have you looked at the longdivision package?

i.e.

\usepackage{longdivision}
