Going ahead to step 9:
When dividing 640 by 139, we get 4 with a remainder of 84.
Put 4 as the next digit of the answer. 
Result so far: 101093.4
Subtracting 556 from 640 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 10:
If we divide 840 by 139, we get 6 and a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 101093.46
If we take 834 away from 840, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 11:
60 divided by 139 is 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 101093.46
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 12:
600 divided by 139 is 4 with a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 101093.4604
Deduct 556 from 600 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 13:
When dividing 440 by 139, we get 3 with a remainder of 23.
The next digit of our result is 3. 
Result so far: 101093.46043
If we subtract 417 from 440, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 14:
230 divided by 139 is 1 with a remainder of 91.
Record the quotient 1 as the next digit in the result. 
Result so far: 101093.460431
Subtract 139 from 230 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Step 15:
139 can be fit into 910 6 times, resulting in a remainder of 76.
The next digit of our result is 6. 
Result so far: 101093.4604316
The remainder is 76 after subtracting 834 from 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 16:
139 goes into 760 5 times with a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 101093.46043165
Deduct 695 from 760 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.
