The div() function computes
      the value numerator/denominator and returns the
      quotient and remainder in a structure named div_t that contains two integer members (in
      unspecified order) named quot
      and rem. The quotient is rounded
      toward zero. The result satisfies quot*denominator+rem = numerator.
The ldiv(), lldiv(), and imaxdiv() functions do the same, dividing
      numbers of the indicated type and returning the result in a
      structure of the indicated name, in all cases with fields
      quot and rem of the same type as the function
      arguments.
