With

\[

\end{document}
we get something similar to the image in this question.
The line for the table in the long division looks like a closed parenthesis ) and a line. The two appear disjoint. I would like to make them connected and, if possible, replace the parenthesis with a vertical straight line.
How to do this?
Note: In the documentation I saw style=D. It has straight lines, but the position of the numerator and denominator are swapped. I am writing for people that are used to the table written as in the default style. I would like to still have them like that, but with the separator looking nicer, in particular connected.
