We're dividing 12806244 by 399 
We want to figure out the number of times 12806244 can be divided by 399.

On to step 1:
The number 399 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
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 / 399

Advancing to step 2:
12 divided by 399 is 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 399

Moving on to step 3:
The number 399 fits into 128 0 times, leaving a remainder of 128.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 128, we end up with 128.
Append the next digit (0) from the dividend to 128 and continue with: 1280 / 399

Moving on to step 4:
399 can be fit into 1280 3 times, resulting in a remainder of 83.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 83 after subtracting 1197 from 1280.
Fetch the next digit (6) from the dividend, attach it to 83 and continue: 836 / 399

Going ahead to step 5:
When dividing 836 by 399, we get 2 with a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 32.0
If we take 798 away from 836, we end up with 38.
Fetch the next digit (2) from the dividend, attach it to 38 and continue: 382 / 399

Moving on to step 6:
If we divide 382 by 399, we get 0 and a remainder of 382.
Use 0 as the next digit of our solution. 
Result so far: 320.0
If we subtract 0 from 382, we get 382.
Fetch the next digit (4) from the dividend, attach it to 382 and continue: 3824 / 399

Moving on to step 7:
3824 divided by 399 is 9 with a remainder of 233.
Record the quotient 9 as the next digit in the result. 
Result so far: 3209.0
If we take 3591 away from 3824, we end up with 233.
Take the next digit (4) from the dividend and append it to 233, then repeat: 2334 / 399

Moving on to step 8:
399 can be fit into 2334 5 times, resulting in a remainder of 339.
Record the quotient 5 as the next digit in the result. 
Result so far: 32095.0
Subtracting 1995 from 2334 leaves us with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Going ahead to step 9:
399 can be fit into 3390 8 times, resulting in a remainder of 198.
Use 8 as the next digit of our solution. 
Result so far: 32095.8
If we subtract 3192 from 3390, we get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Moving on to step 10:
399 goes into 1980 4 times with a remainder of 384.
Put 4 as the next digit of the answer. 
Result so far: 32095.84
If we take 1596 away from 1980, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Advancing to step 11:
399 goes into 3840 9 times with a remainder of 249.
Use 9 as the next digit of our solution. 
Result so far: 32095.849
Subtract 3591 from 3840 to get 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

On to step 12:
If we divide 2490 by 399, we get 6 and a remainder of 96.
Use 6 as the next digit of our solution. 
Result so far: 32095.8496
Subtract 2394 from 2490 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.

Moving on to step 13:
399 goes into 960 2 times with a remainder of 162.
Write down 2 as next digit of the result. 
Result so far: 32095.84962
If we subtract 798 from 960, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Let's proceed to step 14:
399 can be fit into 1620 4 times, resulting in a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 32095.849624
Subtracting 1596 from 1620 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 15:
399 goes into 240 0 times with a remainder of 240.
Put 0 as the next digit of the answer. 
Result so far: 32095.849624
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 16:
If we divide 2400 by 399, we get 6 and a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 32095.84962406
Subtract 2394 from 2400 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

In conclusion, the division gives 32095.84962406 with a balance of 6e-09.
