When dividing 8180 by 870, we get 9 with a remainder of 350.
The number 9 becomes the next digit in our result. 
Result so far: 55199.9
The remainder is 350 after subtracting 7830 from 8180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 10:
When dividing 3500 by 870, we get 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 55199.94
If we take 3480 away from 3500, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
200 divided by 870 is 0 with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 55199.94
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 12:
If we divide 2000 by 870, we get 2 and a remainder of 260.
Write down 2 as next digit of the result. 
Result so far: 55199.9402
Deduct 1740 from 2000 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 13:
2600 divided by 870 is 2 with a remainder of 860.
Use 2 as the next digit of our solution. 
Result so far: 55199.94022
Subtracting 1740 from 2600 leaves us with 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

The final result is 55199.94022 with a remainder of 0.00086.
