The number 8 becomes the next digit in our result. 
Result so far: 15188.0
Deduct 24 from 24 and we're left with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 3

Let's proceed to step 6:
3 can be fit into 3 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 151881.0
