We divide 12931155 by 102
We want to divide 12931155 by 102.

Moving on to step 1:
102 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 102

On to step 2:
The number 102 fits into 12 0 times, leaving a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 102

Let's proceed to step 3:
If we divide 129 by 102, we get 1 and a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 102 away from 129, we end up with 27.
Fetch the next digit (3) from the dividend, attach it to 27 and continue: 273 / 102

Step 4:
273 divided by 102 is 2 with a remainder of 69.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 204 from 273 to get 69.
Include the next digit (1) from the dividend after 69, then repeat: 691 / 102

Let's proceed to step 5:
When dividing 691 by 102, we get 6 with a remainder of 79.
The number 6 becomes the next digit in our result. 
Result so far: 126.0
Subtracting 612 from 691 leaves us with 79.
Include the next digit (1) from the dividend after 79, then repeat: 791 / 102

Step 6:
102 can be fit into 791 7 times, resulting in a remainder of 77.
Record the quotient 7 as the next digit in the result. 
Result so far: 1267.0
The remainder is 77 after subtracting 714 from 791.
Grab the next digit (5) from the dividend, add it to 77, then carry on: 775 / 102

Let's proceed to step 7:
The number 102 fits into 775 7 times, leaving a remainder of 61.
The number 7 becomes the next digit in our result. 
Result so far: 12677.0
Subtract 714 from 775 to get 61.
Take the next digit (5) from the dividend and append it to 61, then repeat: 615 / 102

Moving on to step 8:
If we divide 615 by 102, we get 6 and a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 126776.0
Deduct 612 from 615 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 9:
30 divided by 102 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 126776.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
102 can be fit into 300 2 times, resulting in a remainder of 96.
Put 2 as the next digit of the answer. 
Result so far: 126776.02
If we take 204 away from 300, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 11:
102 can be fit into 960 9 times, resulting in a remainder of 42.
Record the quotient 9 as the next digit in the result. 
Result so far: 126776.029
If we take 918 away from 960, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 12:
420 divided by 102 is 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 126776.0294
If we take 408 away from 420, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
The number 102 fits into 120 1 times, leaving a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 126776.02941
If we take 102 away from 120, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 14:
If we divide 180 by 102, we get 1 and a remainder of 78.
Use 1 as the next digit of our solution. 
Result so far: 126776.029411
If we take 102 away from 180, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

After the division, we end up with 126776.029411 and a remainder of 7.8e-06.
