\longdivision using [separators in work = false] generates a Missing number error

Question

I’ve spent a bit trying to debug this, but wanted to make sure it wasn’t a known bug before killing myself.

I’m trying to use the \longdivision{} command in a LaTeXit equation. It’s alone in the equation, and I have \usepackage{longdivision} in the header.

Used alone (\longdivision{2345}{9999}) all is well. When I add separators in work (\longdivision[separators in work = false]{2345}{9999}), I get an error Missing number, treated as zero. I’ve tried in standard and text modes.

I’ve also tried in an absolutely vanilla TeX document and get a similar error.

\documentclass{article}
\usepackage{longdivision}

\longdivision[separators in work = false]{14.1}{3}
\end{document}

gives

I'm not sure if I should contact the package author on something like this.

In longdivision.sty prior to version 1.2.0 (released during the lifetime of TeX Live 2020) there is no separators in work` option.

Update your TeX system. Possibly downloading the most recent version of longdivision from CTAN might work, if you want to wait for upgrading.
