We're dividing 84511163 by 870 
We want to divide 84511163 by 870.

Going ahead to step 1:
870 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 870

On to step 2:
When dividing 84 by 870, we get 0 with a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 84 leaves us with 84.
Fetch the next digit (5) from the dividend, attach it to 84 and continue: 845 / 870

Step 3:
870 goes into 845 0 times with a remainder of 845.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 845 and we're left with 845.
Bring next digit (1) of the dividend behind the 845 and repeat the process: 8451 / 870

Going ahead to step 4:
870 can be fit into 8451 9 times, resulting in a remainder of 621.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 621 after subtracting 7830 from 8451.
Bring next digit (1) of the dividend behind the 621 and repeat the process: 6211 / 870

Going ahead to step 5:
6211 divided by 870 is 7 with a remainder of 121.
Write down 7 as next digit of the result. 
Result so far: 97.0
If we take 6090 away from 6211, we end up with 121.
Bring next digit (1) of the dividend behind the 121 and repeat the process: 1211 / 870

Step 6:
1211 divided by 870 is 1 with a remainder of 341.
The next digit of our result is 1. 
Result so far: 971.0
Subtract 870 from 1211 to get 341.
Bring next digit (6) of the dividend behind the 341 and repeat the process: 3416 / 870

Moving on to step 7:
The number 870 fits into 3416 3 times, leaving a remainder of 806.
Write down 3 as next digit of the result. 
Result so far: 9713.0
If we subtract 2610 from 3416, we get 806.
Take the next digit (3) from the dividend and append it to 806, then repeat: 8063 / 870

Moving on to step 8:
870 goes into 8063 9 times with a remainder of 233.
The next digit of our result is 9. 
Result so far: 97139.0
The remainder is 233 after subtracting 7830 from 8063.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Advancing to step 9:
870 goes into 2330 2 times with a remainder of 590.
The number 2 becomes the next digit in our result. 
Result so far: 97139.2
Subtract 1740 from 2330 to get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

On to step 10:
870 can be fit into 5900 6 times, resulting in a remainder of 680.
The number 6 becomes the next digit in our result. 
Result so far: 97139.26
If we subtract 5220 from 5900, we get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Moving on to step 11:
The number 870 fits into 6800 7 times, leaving a remainder of 710.
Put 7 as the next digit of the answer. 
Result so far: 97139.267
Subtract 6090 from 6800 to get 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Step 12:
When dividing 7100 by 870, we get 8 with a remainder of 140.
Put 8 as the next digit of the answer. 
Result so far: 97139.2678
The remainder is 140 after subtracting 6960 from 7100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 13:
870 goes into 1400 1 times with a remainder of 530.
The number 1 becomes the next digit in our result. 
Result so far: 97139.26781
If we take 870 away from 1400, we end up with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Let's proceed to step 14:
The number 870 fits into 5300 6 times, leaving a remainder of 80.
Put 6 as the next digit of the answer. 
Result so far: 97139.267816
If we subtract 5220 from 5300, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 15:
870 goes into 800 0 times with a remainder of 800.
Record the quotient 0 as the next digit in the result. 
Result so far: 97139.267816
Deduct 0 from 800 and we're left with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Going ahead to step 16:
When dividing 8000 by 870, we get 9 with a remainder of 170.
Put 9 as the next digit of the answer. 
Result so far: 97139.26781609
Subtract 7830 from 8000 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Our division results in 97139.26781609 with a remaining 1.7e-07.
