I use `polynom`, with `\polylongdiv[style=D]` example

```
\polylongdiv[style=D]{6x^3-2x^2+x+3}{x^2-x+1}
```

I see [here](https://drive.google.com/file/d/1uQAovaBLxdPx0TlpsnzK4dienCt3dG3r/view) and copy this code 

```
\usepackage{xpatch}
\newlength\mypolydepth
\makeatletter
\xpatchcmd\pld@ArrangeResult{\vrule height 2.25ex}{\rule{0pt}{2.2ex}\smash{\vrule height 2.25ex depth \mypolydepth}}{}{\fail}
\makeatother
\newcommand\mypolylongdiv[3][style=D]{%
	\setlength\mypolydepth{0pt}%
	\setbox0=\hbox{\polylongdiv[#1]{#2}{#3}}%
	\setlength\mypolydepth{\dimexpr\dp0-1.3\baselineskip}%
	\polylongdiv[#1]{#2}{#3}%
}
```
to get 

```
