I'm wondering whether this needs to be a change to the API, or if it might be
better implemented as a purely internal optimisation to BCMath / Number - in
some way memoize both the quotient and the remainder when either div or mod is
called, and then document for users that calling one after the other will be
extremely cheap to run.
But maybe that brings up too many questions about memory usage - e.g. is the
memory for this reserved in advance for each instance of Number, or allocated
when one of these functions is called, and should it be freed even while the
object remains in scope to avoid using lots of memory if many numbers are
divided or modded.
