Division vs DIV - Valentin's findings

[J-F Garnier]

These cases are not rare at all, as soon as the dividend is >1E11 such as (4E11+7)/4 --> 10000000002 that clearly illustrates what is happening.
Although I don't have a rigorous reasoning, I don't believe the problem can occur with dividend X<1E11, so IP(X/Y) is then safe for integer division.
This is not specific to the 71B or Saturn machines, it happens as well on the 10-digit 41C and 34-digit Free42 with the 1E9 and 1E33 limits, respectively.

Rule of the thumb: pay attention to integer divisions when the dividend is less than a factor of 10 from the maximum integer.
