Solution :

class Solution{
    static int evenlyDivides(int N){
        int evenD = 0,cp=N;
        while(cp>0){
            int lastD = cp%10;
            if(lastD ==0){
                cp /= 10;
                continue;
            }
            if(N%lastD==0){
                evenD++;
            }
            cp = cp/10;
        }
        return evenD;
    }
}
