We look at the division of 13039855 by 869 
We want to divide 13039855 by 869.

Let's proceed to step 1:
If we divide 1 by 869, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 869

Step 2:
869 can be fit into 13 0 times, resulting in a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 869

On to step 3:
869 can be fit into 130 0 times, resulting in a remainder of 130.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 130 to get 130.
Take the next digit (3) from the dividend and append it to 130, then repeat: 1303 / 869

Let's proceed to step 4:
1303 divided by 869 is 1 with a remainder of 434.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 869 from 1303, we get 434.
Take the next digit (9) from the dividend and append it to 434, then repeat: 4349 / 869

Advancing to step 5:
If we divide 4349 by 869, we get 5 and a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we subtract 4345 from 4349, we get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 869

On to step 6:
If we divide 48 by 869, we get 0 and a remainder of 48.
The next digit of our result is 0. 
Result so far: 150.0
The remainder is 48 after subtracting 0 from 48.
Fetch the next digit (5) from the dividend, attach it to 48 and continue: 485 / 869

Step 7:
869 can be fit into 485 0 times, resulting in a remainder of 485.
Record the quotient 0 as the next digit in the result. 
Result so far: 1500.0
Subtract 0 from 485 to get 485.
Append the next digit (5) from the dividend to 485 and continue with: 4855 / 869

Let's proceed to step 8:
869 goes into 4855 5 times with a remainder of 510.
Write down 5 as next digit of the result. 
Result so far: 15005.0
Subtracting 4345 from 4855 leaves us with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Step 9:
869 goes into 5100 5 times with a remainder of 755.
Use 5 as the next digit of our solution. 
Result so far: 15005.5
Deduct 4345 from 5100 and we're left with 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

Step 10:
If we divide 7550 by 869, we get 8 and a remainder of 598.
Use 8 as the next digit of our solution. 
Result so far: 15005.58
If we subtract 6952 from 7550, we get 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Advancing to step 11:
The number 869 fits into 5980 6 times, leaving a remainder of 766.
Record the quotient 6 as the next digit in the result. 
Result so far: 15005.586
If we subtract 5214 from 5980, we get 766.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7660, and continue the process.

On to step 12:
When dividing 7660 by 869, we get 8 with a remainder of 708.
Record the quotient 8 as the next digit in the result. 
Result so far: 15005.5868
Subtracting 6952 from 7660 leaves us with 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

On to step 13:
869 goes into 7080 8 times with a remainder of 128.
Write down 8 as next digit of the result. 
Result so far: 15005.58688
Deduct 6952 from 7080 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

In conclusion, the division gives 15005.58688 with a balance of 0.000128.
