Need advice - INTEST

Hi! Can anyone help me with http://www.spoj.pl/problems/INTEST/ in C++.
I've passed it in 5.59 but i see there are submissions with exec time =~0.5.
Here is my code - what can i improve to get have at least 1.5 - 1.0 sec?

#include <stdio.h>
int main()
{
  int n, k, count = 0, next;
  scanf("%i %i", &n, &k);
  do{
    scanf("%i", &next);
    count += !(next % k);
  }while(--n);
  printf("%i", count);
  return 0;
}
