Subtracting 18 from 18 leaves us with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 2

Let's proceed to step 6:
2 can be fit into 2 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 101791.0
If we subtract 2 from 2, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 101791.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.
