We look at the division of 12997889 by 756 
Let's see how many times 756 fits into 12997889.

Advancing to step 1:
The number 756 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 756

On to step 2:
756 can be fit into 12 0 times, resulting in a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 756

On to step 3:
756 can be fit into 129 0 times, resulting in a remainder of 129.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 129 and we're left with 129.
Take the next digit (9) from the dividend and append it to 129, then repeat: 1299 / 756

Step 4:
756 can be fit into 1299 1 times, resulting in a remainder of 543.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 756 from 1299 and we're left with 543.
Bring next digit (7) of the dividend behind the 543 and repeat the process: 5437 / 756

Going ahead to step 5:
The number 756 fits into 5437 7 times, leaving a remainder of 145.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtracting 5292 from 5437 leaves us with 145.
Fetch the next digit (8) from the dividend, attach it to 145 and continue: 1458 / 756

On to step 6:
When dividing 1458 by 756, we get 1 with a remainder of 702.
The next digit of our result is 1. 
Result so far: 171.0
Subtract 756 from 1458 to get 702.
Include the next digit (8) from the dividend after 702, then repeat: 7028 / 756

Advancing to step 7:
The number 756 fits into 7028 9 times, leaving a remainder of 224.
Use 9 as the next digit of our solution. 
Result so far: 1719.0
Subtracting 6804 from 7028 leaves us with 224.
Take the next digit (9) from the dividend and append it to 224, then repeat: 2249 / 756

Let's proceed to step 8:
If we divide 2249 by 756, we get 2 and a remainder of 737.
Use 2 as the next digit of our solution. 
Result so far: 17192.0
If we take 1512 away from 2249, we end up with 737.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7370, and continue the process.

Let's proceed to step 9:
When dividing 7370 by 756, we get 9 with a remainder of 566.
Use 9 as the next digit of our solution. 
Result so far: 17192.9
Deduct 6804 from 7370 and we're left with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Let's proceed to step 10:
The number 756 fits into 5660 7 times, leaving a remainder of 368.
Use 7 as the next digit of our solution. 
Result so far: 17192.97
If we take 5292 away from 5660, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Advancing to step 11:
3680 divided by 756 is 4 with a remainder of 656.
Use 4 as the next digit of our solution. 
Result so far: 17192.974
Deduct 3024 from 3680 and we're left with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Going ahead to step 12:
756 can be fit into 6560 8 times, resulting in a remainder of 512.
Record the quotient 8 as the next digit in the result. 
Result so far: 17192.9748
The remainder is 512 after subtracting 6048 from 6560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Step 13:
If we divide 5120 by 756, we get 6 and a remainder of 584.
Write down 6 as next digit of the result. 
Result so far: 17192.97486
Deduct 4536 from 5120 and we're left with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Let's proceed to step 14:
756 goes into 5840 7 times with a remainder of 548.
Put 7 as the next digit of the answer. 
Result so far: 17192.974867
If we take 5292 away from 5840, we end up with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Going ahead to step 15:
5480 divided by 756 is 7 with a remainder of 188.
Use 7 as the next digit of our solution. 
Result so far: 17192.9748677
The remainder is 188 after subtracting 5292 from 5480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Our division results in 17192.9748677 with a remaining 1.88e-06.
