My memory failed me on a detail if I want to be rigorous. In the definition
of q and r, r is a natural number, but q is a relative number, not a
natural.

There exists unique natural numbers q and r such as:
a = b*q+r
0 = r b
q is defined as the quotient, r is defined as the remainder.
So if the % operator wants to match that math definition, its results should
