Let's divide 13015935 by 869
We want to figure out the number of times 13015935 can be divided by 869.

Going ahead to step 1:
The number 869 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 869

Going ahead to step 2:
If we divide 13 by 869, we get 0 and a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 869

Let's proceed to step 3:
The number 869 fits into 130 0 times, leaving a remainder of 130.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 130, we get 130.
Fetch the next digit (1) from the dividend, attach it to 130 and continue: 1301 / 869

Advancing to step 4:
1301 divided by 869 is 1 with a remainder of 432.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 432 after subtracting 869 from 1301.
Bring next digit (5) of the dividend behind the 432 and repeat the process: 4325 / 869

Step 5:
When dividing 4325 by 869, we get 4 with a remainder of 849.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 3476 from 4325 to get 849.
Bring next digit (9) of the dividend behind the 849 and repeat the process: 8499 / 869

On to step 6:
When dividing 8499 by 869, we get 9 with a remainder of 678.
Use 9 as the next digit of our solution. 
Result so far: 149.0
Subtracting 7821 from 8499 leaves us with 678.
Take the next digit (3) from the dividend and append it to 678, then repeat: 6783 / 869

Moving on to step 7:
The number 869 fits into 6783 7 times, leaving a remainder of 700.
Record the quotient 7 as the next digit in the result. 
Result so far: 1497.0
The remainder is 700 after subtracting 6083 from 6783.
Grab the next digit (5) from the dividend, add it to 700, then carry on: 7005 / 869

On to step 8:
The number 869 fits into 7005 8 times, leaving a remainder of 53.
The next digit of our result is 8. 
Result so far: 14978.0
The remainder is 53 after subtracting 6952 from 7005.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 9:
869 can be fit into 530 0 times, resulting in a remainder of 530.
The number 0 becomes the next digit in our result. 
Result so far: 14978.0
The remainder is 530 after subtracting 0 from 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 10:
If we divide 5300 by 869, we get 6 and a remainder of 86.
Record the quotient 6 as the next digit in the result. 
Result so far: 14978.06
Subtracting 5214 from 5300 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 11:
If we divide 860 by 869, we get 0 and a remainder of 860.
Use 0 as the next digit of our solution. 
Result so far: 14978.06
If we take 0 away from 860, we end up with 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

Let's proceed to step 12:
8600 divided by 869 is 9 with a remainder of 779.
Put 9 as the next digit of the answer. 
Result so far: 14978.0609
Deduct 7821 from 8600 and we're left with 779.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7790, and continue the process.

Let's proceed to step 13:
869 can be fit into 7790 8 times, resulting in a remainder of 838.
The next digit of our result is 8. 
Result so far: 14978.06098
Subtracting 6952 from 7790 leaves us with 838.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8380, and continue the process.

On to step 14:
If we divide 8380 by 869, we get 9 and a remainder of 559.
Put 9 as the next digit of the answer. 
Result so far: 14978.060989
The remainder is 559 after subtracting 7821 from 8380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

Advancing to step 15:
869 can be fit into 5590 6 times, resulting in a remainder of 376.
Record the quotient 6 as the next digit in the result. 
Result so far: 14978.0609896
The remainder is 376 after subtracting 5214 from 5590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Going ahead to step 16:
The number 869 fits into 3760 4 times, leaving a remainder of 284.
Use 4 as the next digit of our solution. 
Result so far: 14978.06098964
Subtracting 3476 from 3760 leaves us with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Our division results in 14978.06098964 with a remaining 2.84e-07.
