Splitting integer

If I input a 5 digit number, how would I split it up into it's individual digits? I am told that I must use the modulus and division operators however I am still new to the modulus operator and am not quite sure how to go about this.

eg.
Input --> 12321
Splits into 1 2 3 2 1

Code:

---

int x, y;
x = 236;
y = x % 10;  // y contains 6, modulus operator
x = x / 10;  // x contains 23, standard integer division
