the package polynom offers its style C, which is pretty close to my wishes, but not perfect:
I like to get the subtracted part in brackets with an leading minus like here:

Example:
\documentclass{standalone}
\usepackage{polynom}
\begin{document}
\polylongdiv[style=C,div=:,vars=x]{x^3-12x^2+5x+150}{x-5}
\end{document}
I would like to get the upper result.
Does anyone know, how to achive this?
Thanks in advance!
