public static void main(String[] args) {
int t;
int count = 0;
int n;
    Scanner input = new Scanner(System.in);
    t = input.nextInt();
    int inc=1;
    int[] array = new int[t];
    for (int i = 0; i< array.length;i++){
         n =input.nextInt();
        count = 0;
        inc=1;
        while(n/Math.pow(5,inc)>=1){
            count+=n/Math.pow(5,inc);
            inc ++;
        }array[i]=count;
    }
    for(int i=0;i<array.length;i++){
        System.out.println(array[i]);
    }
}
