It calls itself over and over until an exit condition is reached, and then passes the results back up the call stack, potentially modifying them on the way up as well. Done. The choice of whether to use recursion to solve a problem depends in large part on the nature of the problem. A physical world example would be to place two parallel mirrors facing each other.
