Calculate by successive subtractions the integer quotient and the remainder of the integer division of two integers entered on the keyboard.

#include <conio.h>

void main()

 	int DEN;   /* denominator of the integer QUOision */

 	printf("Enter the numerator   : ");
 	scanf("%d", &NUM);
 	printf("Enter the denominator : ");
 	scanf("%d", &DEN);

 	QUO=0;
 	while(REM>=DEN)

 	printf(" %d = %d * %d + %d\n", NUM, DEN, QUO, REM);
