We're dividing 15415992 by 756 
We want to divide 15415992 by 756.

Step 1:
The number 756 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 756

Going ahead to step 2:
If we divide 15 by 756, we get 0 and a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 756

Advancing to step 3:
The number 756 fits into 154 0 times, leaving a remainder of 154.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 154 and we're left with 154.
Include the next digit (1) from the dividend after 154, then repeat: 1541 / 756

Advancing to step 4:
When dividing 1541 by 756, we get 2 with a remainder of 29.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 1512 from 1541, we get 29.
Fetch the next digit (5) from the dividend, attach it to 29 and continue: 295 / 756

Step 5:
756 can be fit into 295 0 times, resulting in a remainder of 295.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we subtract 0 from 295, we get 295.
Grab the next digit (9) from the dividend, add it to 295, then carry on: 2959 / 756

Advancing to step 6:
If we divide 2959 by 756, we get 3 and a remainder of 691.
Write down 3 as next digit of the result. 
Result so far: 203.0
Subtract 2268 from 2959 to get 691.
Take the next digit (9) from the dividend and append it to 691, then repeat: 6919 / 756

On to step 7:
6919 divided by 756 is 9 with a remainder of 115.
Put 9 as the next digit of the answer. 
Result so far: 2039.0
If we subtract 6804 from 6919, we get 115.
Bring next digit (2) of the dividend behind the 115 and repeat the process: 1152 / 756

Let's proceed to step 8:
1152 divided by 756 is 1 with a remainder of 396.
The next digit of our result is 1. 
Result so far: 20391.0
Subtract 756 from 1152 to get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Going ahead to step 9:
756 can be fit into 3960 5 times, resulting in a remainder of 180.
The next digit of our result is 5. 
Result so far: 20391.5
The remainder is 180 after subtracting 3780 from 3960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 10:
The number 756 fits into 1800 2 times, leaving a remainder of 288.
The number 2 becomes the next digit in our result. 
Result so far: 20391.52
Subtract 1512 from 1800 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 11:
If we divide 2880 by 756, we get 3 and a remainder of 612.
Record the quotient 3 as the next digit in the result. 
Result so far: 20391.523
The remainder is 612 after subtracting 2268 from 2880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Moving on to step 12:
The number 756 fits into 6120 8 times, leaving a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 20391.5238
The remainder is 72 after subtracting 6048 from 6120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 13:
720 divided by 756 is 0 with a remainder of 720.
Write down 0 as next digit of the result. 
Result so far: 20391.5238
If we subtract 0 from 720, we get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Going ahead to step 14:
If we divide 7200 by 756, we get 9 and a remainder of 396.
The number 9 becomes the next digit in our result. 
Result so far: 20391.523809
Subtract 6804 from 7200 to get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Step 15:
756 can be fit into 3960 5 times, resulting in a remainder of 180.
Record the quotient 5 as the next digit in the result. 
Result so far: 20391.5238095
If we subtract 3780 from 3960, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 16:
756 can be fit into 1800 2 times, resulting in a remainder of 288.
Put 2 as the next digit of the answer. 
Result so far: 20391.52380952
Subtracting 1512 from 1800 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Our division results in 20391.52380952 with a remaining 2.88e-07.
