Integer division really ask how many times can one subtract the numerator from the denominator without going negative (or how many times does the numerator "go into" the denominator). It may seem a nuisance, but int division is a useful construct and must be supported (and be the default). (If you have 10 people to transport in cars which hold four (all can drive) 10/4 = 3 ;) )
