12798372 divided by 816 
We want to divide 12798372 by 816.

Moving on to step 1:
816 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 816

Moving on to step 2:
When dividing 12 by 816, we get 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 816

On to step 3:
If we divide 127 by 816, we get 0 and a remainder of 127.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 127, we end up with 127.
Append the next digit (9) from the dividend to 127 and continue with: 1279 / 816

Going ahead to step 4:
When dividing 1279 by 816, we get 1 with a remainder of 463.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 816 from 1279 leaves us with 463.
Take the next digit (8) from the dividend and append it to 463, then repeat: 4638 / 816

Let's proceed to step 5:
4638 divided by 816 is 5 with a remainder of 558.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 558 after subtracting 4080 from 4638.
Grab the next digit (3) from the dividend, add it to 558, then carry on: 5583 / 816

Going ahead to step 6:
816 can be fit into 5583 6 times, resulting in a remainder of 687.
Record the quotient 6 as the next digit in the result. 
Result so far: 156.0
If we subtract 4896 from 5583, we get 687.
Append the next digit (7) from the dividend to 687 and continue with: 6877 / 816

Let's proceed to step 7:
When dividing 6877 by 816, we get 8 with a remainder of 349.
The number 8 becomes the next digit in our result. 
Result so far: 1568.0
The remainder is 349 after subtracting 6528 from 6877.
Fetch the next digit (2) from the dividend, attach it to 349 and continue: 3492 / 816

Advancing to step 8:
The number 816 fits into 3492 4 times, leaving a remainder of 228.
The number 4 becomes the next digit in our result. 
Result so far: 15684.0
The remainder is 228 after subtracting 3264 from 3492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Step 9:
816 goes into 2280 2 times with a remainder of 648.
Record the quotient 2 as the next digit in the result. 
Result so far: 15684.2
The remainder is 648 after subtracting 1632 from 2280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Step 10:
If we divide 6480 by 816, we get 7 and a remainder of 768.
Use 7 as the next digit of our solution. 
Result so far: 15684.27
Deduct 5712 from 6480 and we're left with 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Going ahead to step 11:
The number 816 fits into 7680 9 times, leaving a remainder of 336.
Use 9 as the next digit of our solution. 
Result so far: 15684.279
The remainder is 336 after subtracting 7344 from 7680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Going ahead to step 12:
816 can be fit into 3360 4 times, resulting in a remainder of 96.
The number 4 becomes the next digit in our result. 
Result so far: 15684.2794
Subtract 3264 from 3360 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 13:
816 goes into 960 1 times with a remainder of 144.
Record the quotient 1 as the next digit in the result. 
Result so far: 15684.27941
Subtracting 816 from 960 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 14:
816 goes into 1440 1 times with a remainder of 624.
The number 1 becomes the next digit in our result. 
Result so far: 15684.279411
If we subtract 816 from 1440, we get 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

After the division, we end up with 15684.279411 and a remainder of 6.24e-05.
