C :

#include <stdio.h>
int main(){
    long long n, b, cnt;
    while(scanf("%lld %lld", &n, &b) != EOF){
        int i;
        cnt = 0;
        for(i = b; i <= n; i += b) cnt++;
        printf("%lld\n", cnt);
    }
    return 0;
}

C++ :

#include "cstdio"
int main()
{
	int a,b;
	while(scanf("%d%d",&a,&b)!=EOF)
		printf("%d\n",a/b);
	return 0;
}

Java :

import java.util.Scanner;
public class Main
{
	public static void main(String[] args)
	{
		Scanner sc=new Scanner(System.in);
		while(sc.hasNext())
		{
			int n=sc.nextInt();
			int b=sc.nextInt();
			System.out.println(n/b);
		}
	}
}
