When dealing with integer quantities and together with modulo, it's pretty natural. n/d gives the integer result, n%d gives the rest. n/2 for example always gives you the "middle" element. And in e.g. a loop where you e.g. transmit elements in blocks, you handle full blocks n/blocksize times, followed by a partial block with n%blocksize elements. It's not always what you want, but it's pretty reasonable. The alternative would be if it always rounds up, which seems weirder to me. I don't think rounding to the nearest integer makes sense with integer quantities at all, that's strictly a real number operation.
