12900370 ÷ 796 
We want to divide 12900370 by 796.

Advancing to step 1:
When dividing 1 by 796, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 796

On to step 2:
796 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 796

Let's proceed to step 3:
When dividing 129 by 796, we get 0 with a remainder of 129.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 129 and we're left with 129.
Fetch the next digit (0) from the dividend, attach it to 129 and continue: 1290 / 796

Advancing to step 4:
796 goes into 1290 1 times with a remainder of 494.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 796 from 1290 and we're left with 494.
Grab the next digit (0) from the dividend, add it to 494, then carry on: 4940 / 796

Going ahead to step 5:
796 can be fit into 4940 6 times, resulting in a remainder of 164.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtracting 4776 from 4940 leaves us with 164.
Grab the next digit (3) from the dividend, add it to 164, then carry on: 1643 / 796

Advancing to step 6:
When dividing 1643 by 796, we get 2 with a remainder of 51.
Record the quotient 2 as the next digit in the result. 
Result so far: 162.0
If we take 1592 away from 1643, we end up with 51.
Append the next digit (7) from the dividend to 51 and continue with: 517 / 796

Step 7:
The number 796 fits into 517 0 times, leaving a remainder of 517.
Record the quotient 0 as the next digit in the result. 
Result so far: 1620.0
The remainder is 517 after subtracting 0 from 517.
Append the next digit (0) from the dividend to 517 and continue with: 5170 / 796

Advancing to step 8:
If we divide 5170 by 796, we get 6 and a remainder of 394.
Use 6 as the next digit of our solution. 
Result so far: 16206.0
If we take 4776 away from 5170, we end up with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Going ahead to step 9:
796 goes into 3940 4 times with a remainder of 756.
Use 4 as the next digit of our solution. 
Result so far: 16206.4
Deduct 3184 from 3940 and we're left with 756.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7560, and continue the process.

Advancing to step 10:
The number 796 fits into 7560 9 times, leaving a remainder of 396.
Write down 9 as next digit of the result. 
Result so far: 16206.49
Subtract 7164 from 7560 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 11:
When dividing 3960 by 796, we get 4 with a remainder of 776.
The next digit of our result is 4. 
Result so far: 16206.494
If we take 3184 away from 3960, we end up with 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

Moving on to step 12:
The number 796 fits into 7760 9 times, leaving a remainder of 596.
The next digit of our result is 9. 
Result so far: 16206.4949
Subtract 7164 from 7760 to get 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Going ahead to step 13:
The number 796 fits into 5960 7 times, leaving a remainder of 388.
Put 7 as the next digit of the answer. 
Result so far: 16206.49497
The remainder is 388 after subtracting 5572 from 5960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Going ahead to step 14:
If we divide 3880 by 796, we get 4 and a remainder of 696.
The next digit of our result is 4. 
Result so far: 16206.494974
If we take 3184 away from 3880, we end up with 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Step 15:
796 goes into 6960 8 times with a remainder of 592.
Record the quotient 8 as the next digit in the result. 
Result so far: 16206.4949748
Subtracting 6368 from 6960 leaves us with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Step 16:
5920 divided by 796 is 7 with a remainder of 348.
Write down 7 as next digit of the result. 
Result so far: 16206.49497487
Deduct 5572 from 5920 and we're left with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Our division results in 16206.49497487 with a remaining 3.48e-07.
