Ok... They're not big numbers.

Is there a proper method to do these divisions without a calculator?

1104/48 = 23

To do that sum, I would multiply 48 by 10 to get 480 and then double it to get 960. I would then keep subtracting 48 from 144 (1104 - 960) until I get 0. Is there a proper way of doing this?

Thanks.
