13125607 divided by 869 
We want to divide 13125607 by 869.

Advancing to step 1:
869 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 869

On to step 2:
If we divide 13 by 869, we get 0 and a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 869

Moving on to step 3:
131 divided by 869 is 0 with a remainder of 131.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 131 leaves us with 131.
Include the next digit (2) from the dividend after 131, then repeat: 1312 / 869

Advancing to step 4:
The number 869 fits into 1312 1 times, leaving a remainder of 443.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 869 away from 1312, we end up with 443.
Grab the next digit (5) from the dividend, add it to 443, then carry on: 4435 / 869

On to step 5:
869 can be fit into 4435 5 times, resulting in a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 4345 from 4435, we get 90.
Grab the next digit (6) from the dividend, add it to 90, then carry on: 906 / 869

Step 6:
869 goes into 906 1 times with a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 151.0
Deduct 869 from 906 and we're left with 37.
Append the next digit (0) from the dividend to 37 and continue with: 370 / 869

Advancing to step 7:
The number 869 fits into 370 0 times, leaving a remainder of 370.
Record the quotient 0 as the next digit in the result. 
Result so far: 1510.0
Subtracting 0 from 370 leaves us with 370.
Take the next digit (7) from the dividend and append it to 370, then repeat: 3707 / 869

Moving on to step 8:
If we divide 3707 by 869, we get 4 and a remainder of 231.
Use 4 as the next digit of our solution. 
Result so far: 15104.0
If we subtract 3476 from 3707, we get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Let's proceed to step 9:
869 goes into 2310 2 times with a remainder of 572.
The number 2 becomes the next digit in our result. 
Result so far: 15104.2
If we take 1738 away from 2310, we end up with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

On to step 10:
869 can be fit into 5720 6 times, resulting in a remainder of 506.
The next digit of our result is 6. 
Result so far: 15104.26
Subtract 5214 from 5720 to get 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Advancing to step 11:
The number 869 fits into 5060 5 times, leaving a remainder of 715.
The next digit of our result is 5. 
Result so far: 15104.265
The remainder is 715 after subtracting 4345 from 5060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7150, and continue the process.

Advancing to step 12:
869 can be fit into 7150 8 times, resulting in a remainder of 198.
Put 8 as the next digit of the answer. 
Result so far: 15104.2658
Deduct 6952 from 7150 and we're left with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Advancing to step 13:
When dividing 1980 by 869, we get 2 with a remainder of 242.
Record the quotient 2 as the next digit in the result. 
Result so far: 15104.26582
If we subtract 1738 from 1980, we get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

On to step 14:
The number 869 fits into 2420 2 times, leaving a remainder of 682.
The next digit of our result is 2. 
Result so far: 15104.265822
The remainder is 682 after subtracting 1738 from 2420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6820, and continue the process.

The quotient of the division is 15104.265822, and the remainder is 6.82e-05.
