  div_t div( int numerator, int denominator );

The function div() returns the quotient and remainder of the operation numerator / denominator. The div_t structure is defined in stdlib.h, and has at least:

   int quot;   // The quotient
   int rem;    // The remainder         

For example, the following code displays the quotient and remainder of x/y:

   div_t temp;
   temp = div( x, y );
   printf( "%d divided by %d yields %d with a remainder of %d\n",
           x, y, temp.quot, temp.rem );
