We look at the division of 10610570 by 869 
We want to figure out the number of times 10610570 can be divided by 869.

Advancing to step 1:
869 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 869

Going ahead to step 2:
If we divide 10 by 869, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 869

On to step 3:
106 divided by 869 is 0 with a remainder of 106.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 106, we get 106.
Bring next digit (1) of the dividend behind the 106 and repeat the process: 1061 / 869

Moving on to step 4:
869 goes into 1061 1 times with a remainder of 192.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 869 from 1061 and we're left with 192.
Grab the next digit (0) from the dividend, add it to 192, then carry on: 1920 / 869

On to step 5:
When dividing 1920 by 869, we get 2 with a remainder of 182.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 1738 from 1920, we get 182.
Append the next digit (5) from the dividend to 182 and continue with: 1825 / 869

Step 6:
If we divide 1825 by 869, we get 2 and a remainder of 87.
The number 2 becomes the next digit in our result. 
Result so far: 122.0
Deduct 1738 from 1825 and we're left with 87.
Fetch the next digit (7) from the dividend, attach it to 87 and continue: 877 / 869

Advancing to step 7:
If we divide 877 by 869, we get 1 and a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1221.0
If we take 869 away from 877, we end up with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 869

Advancing to step 8:
80 divided by 869 is 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 12210.0
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 9:
The number 869 fits into 800 0 times, leaving a remainder of 800.
The next digit of our result is 0. 
Result so far: 12210.0
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.

Advancing to step 10:
When dividing 8000 by 869, we get 9 with a remainder of 179.
Put 9 as the next digit of the answer. 
Result so far: 12210.09
The remainder is 179 after subtracting 7821 from 8000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Advancing to step 11:
869 goes into 1790 2 times with a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 12210.092
Subtract 1738 from 1790 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 12:
The number 869 fits into 520 0 times, leaving a remainder of 520.
Put 0 as the next digit of the answer. 
Result so far: 12210.092
Deduct 0 from 520 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 13:
5200 divided by 869 is 5 with a remainder of 855.
Record the quotient 5 as the next digit in the result. 
Result so far: 12210.09205
The remainder is 855 after subtracting 4345 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8550, and continue the process.

Moving on to step 14:
If we divide 8550 by 869, we get 9 and a remainder of 729.
Put 9 as the next digit of the answer. 
Result so far: 12210.092059
Deduct 7821 from 8550 and we're left with 729.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7290, and continue the process.

Going ahead to step 15:
869 goes into 7290 8 times with a remainder of 338.
Put 8 as the next digit of the answer. 
Result so far: 12210.0920598
If we subtract 6952 from 7290, we get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Going ahead to step 16:
If we divide 3380 by 869, we get 3 and a remainder of 773.
Write down 3 as next digit of the result. 
Result so far: 12210.09205983
If we take 2607 away from 3380, we end up with 773.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7730, and continue the process.

The quotient of the division is 12210.09205983, and the remainder is 7.73e-07.
