5607 is a special case of this enhancement. 
This one is generalization since any division by constant can be optimized.
Using small divisors only allows some more specialized varations of this
optimization (less accurate but enough for numbers in question).

I'd say this one supersedes 5607, so how about merge your example here and
close 5607 ? (the 2 have to be merged anyway since the root cause is the same)
