When dividing 6220 by 648, we get 9 with a remainder of 388.
Use 9 as the next digit of our solution. 
Result so far: 90188.19
If we subtract 5832 from 6220, we get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Moving on to step 11:
When dividing 3880 by 648, we get 5 with a remainder of 640.
Write down 5 as next digit of the result. 
Result so far: 90188.195
Subtracting 3240 from 3880 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 12:
If we divide 6400 by 648, we get 9 and a remainder of 568.
Record the quotient 9 as the next digit in the result. 
Result so far: 90188.1959
If we subtract 5832 from 6400, we get 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

On to step 13:
648 goes into 5680 8 times with a remainder of 496.
Record the quotient 8 as the next digit in the result. 
Result so far: 90188.19598
Deduct 5184 from 5680 and we're left with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Moving on to step 14:
