Back issues of SigPlan Notices are a good place to look.

As Every Schoolboy Knows, there are at least three sensible definitions of
integer division/remainder, all of which agree which divisor and dividend
are positive.  Common Lisp provides all three, and a fourth, also sensible.

Note that the Pascal standard does not define integer division and
remainder for non-positive divisors.
