C++ :

#include <stdio.h>
int main(){
    int T;
    scanf("%d",&T);
    while(T--){
        int a,b;
        scanf("%d%d",&a,&b);
        if(a%(b+1)==0)  printf("yes\n");
        else printf("no\n");
    }
    return 0;
}

Java :

import java.util.Scanner;

public class Main{
    public static void main(String args[]){
        Scanner cin=new Scanner(System.in);
        int m,n;
        while(cin.hasNext()){
            n=cin.nextInt();
            m=cin.nextInt();
            if(m+n==0)
                break;
            if(n%(m+1)==0)
                System.out.println("yes");
            else
                System.out.println("no");
        }
    }
