Leftover Puppy Treats

You're splitting a bag of treats evenly among a litter of puppies 🐶 — but this time you want to know how many treats are left over after the even split.

You're given the total treats, then the number of puppies. Print the leftover amount.

For example, 10 treats and 3 puppies → print 1 (3 puppies get 3 each, using 9, with 1 left over).
