// macro	divqr
//
// purpose	Calculate the quotient and remainder (e.g. x/y and x%y) at the
//		same time via the div() standard function, but instead of
//		returning a div_t structure, store the quotient in the location
//		specified in the 3rd argument and store the remainder in the
//		location specified in the 4th argument.
//
// arguments	1 (int) divident
//		2 (int) divisor
//		3 (integer *) where to store quotient
//		4 (integer *) where to store remainder
//
// returns	(int) 0
