Re: Unable to use longdivision package with LaTeX

I have now found out that if longdivision is invoked _before_

I have written to the package author describing the behaviour and 
requesting a resolution.

For now, one possible workaround is to place a copy of longdivision.sty in the same folder as the MD file and to replace \longdivision with e.g. \mylongdivision in the following line:
