Going ahead to step 4:
When dividing 2757 by 870, we get 3 with a remainder of 147.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 2610 from 2757 leaves us with 147.
Fetch the next digit (0) from the dividend, attach it to 147 and continue: 1470 / 870

Advancing to step 5:
The number 870 fits into 1470 1 times, leaving a remainder of 600.
Write down 1 as next digit of the result. 
Result so far: 31.0
If we take 870 away from 1470, we end up with 600.
Grab the next digit (8) from the dividend, add it to 600, then carry on: 6008 / 870

Going ahead to step 6:
870 goes into 6008 6 times with a remainder of 788.
Put 6 as the next digit of the answer. 
Result so far: 316.0
The remainder is 788 after subtracting 5220 from 6008.
Include the next digit (5) from the dividend after 788, then repeat: 7885 / 870

On to step 7:
870 can be fit into 7885 9 times, resulting in a remainder of 55.
Put 9 as the next digit of the answer. 
Result so far: 3169.0
Deduct 7830 from 7885 and we're left with 55.
Fetch the next digit (6) from the dividend, attach it to 55 and continue: 556 / 870

On to step 8:
870 can be fit into 556 0 times, resulting in a remainder of 556.
The next digit of our result is 0. 
Result so far: 31690.0
Subtracting 0 from 556 leaves us with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Going ahead to step 9:
When dividing 5560 by 870, we get 6 with a remainder of 340.
The next digit of our result is 6. 
Result so far: 31690.6
Subtract 5220 from 5560 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 10:
870 can be fit into 3400 3 times, resulting in a remainder of 790.
Write down 3 as next digit of the result. 
Result so far: 31690.63
Deduct 2610 from 3400 and we're left with 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Moving on to step 11:
7900 divided by 870 is 9 with a remainder of 70.
Record the quotient 9 as the next digit in the result. 
Result so far: 31690.639
If we subtract 7830 from 7900, 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.

On to step 12:
870 can be fit into 700 0 times, resulting in a remainder of 700.
Put 0 as the next digit of the answer. 
Result so far: 31690.639
If we subtract 0 from 700, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Going ahead to step 13:
The number 870 fits into 7000 8 times, leaving a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 31690.63908
The remainder is 40 after subtracting 6960 from 7000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 14:
The number 870 fits into 400 0 times, leaving a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 31690.63908
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 15:
The number 870 fits into 4000 4 times, leaving a remainder of 520.
Write down 4 as next digit of the result. 
Result so far: 31690.6390804
If we subtract 3480 from 4000, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Advancing to step 16:
If we divide 5200 by 870, we get 5 and a remainder of 850.
Put 5 as the next digit of the answer. 
Result so far: 31690.63908045
Subtracting 4350 from 5200 leaves us with 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8500, and continue the process.

The final result is 31690.63908045 with a remainder of 8.5e-07.
