Record the quotient 4 as the next digit in the result. 
Result so far: 8967.4
If we subtract 360 from 430, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 8:
700 divided by 90 is 7 with a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 8967.47
Subtract 630 from 700 to get 70.
