Crafty Grandma Edith sat her family down during Thanksgiving and told them they couldn’t have any pumpkin pie until they worked out this puzzle. Her 6-year-old granddaughter was the first to solve it! Can you work out what 9183 equals?

8809 = 6 3590 = 2
7111 = 0 6855 = 3
9881 = 5 1012 = 1
6660 = 4 5731 = 0
5531 = 0 9191 = 2
2516 = 1 9183 = ?

I'm really confused about this one, could anyone help me?
