Use 0 as the next digit of our solution. 
Result so far: 7156.1
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.

On to step 9:
When dividing 0 by 90, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7156.1
