为什么这里读进来的数不能做除法？

import java.util.Scanner;

public class value {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Scanner in = new Scanner(System.in);
        int count = 0;
        int value = 0;
        int number = in.nextInt();
        int    num = 0;
        {
            num=number%10;
            count++;
            if(num/count==0)
            {
                value = 1;
            }
            else 
            {
                value = 0;
            }
            number/10;
        }
    }

}

你这是个无效语句呀
