12815711 ÷ 397 
We're looking to find how many times 397 goes into 12815711.

Going ahead to step 1:
The number 397 fits into 1 0 times, leaving 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 / 397

Step 2:
397 can be fit into 12 0 times, resulting in a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 397

On to step 3:
397 can be fit into 128 0 times, resulting in a remainder of 128.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 128, we get 128.
Include the next digit (1) from the dividend after 128, then repeat: 1281 / 397

On to step 4:
If we divide 1281 by 397, we get 3 and a remainder of 90.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 1191 from 1281 leaves us with 90.
Bring next digit (5) of the dividend behind the 90 and repeat the process: 905 / 397

Going ahead to step 5:
If we divide 905 by 397, we get 2 and a remainder of 111.
Use 2 as the next digit of our solution. 
Result so far: 32.0
If we take 794 away from 905, we end up with 111.
Append the next digit (7) from the dividend to 111 and continue with: 1117 / 397

Let's proceed to step 6:
397 can be fit into 1117 2 times, resulting in a remainder of 323.
Put 2 as the next digit of the answer. 
Result so far: 322.0
Subtracting 794 from 1117 leaves us with 323.
Include the next digit (1) from the dividend after 323, then repeat: 3231 / 397

Advancing to step 7:
397 can be fit into 3231 8 times, resulting in a remainder of 55.
Write down 8 as next digit of the result. 
Result so far: 3228.0
If we take 3176 away from 3231, we end up with 55.
Take the next digit (1) from the dividend and append it to 55, then repeat: 551 / 397

Moving on to step 8:
When dividing 551 by 397, we get 1 with a remainder of 154.
Put 1 as the next digit of the answer. 
Result so far: 32281.0
If we take 397 away from 551, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Advancing to step 9:
When dividing 1540 by 397, we get 3 with a remainder of 349.
The number 3 becomes the next digit in our result. 
Result so far: 32281.3
Subtracting 1191 from 1540 leaves us with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Advancing to step 10:
3490 divided by 397 is 8 with a remainder of 314.
Use 8 as the next digit of our solution. 
Result so far: 32281.38
Subtract 3176 from 3490 to get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Going ahead to step 11:
3140 divided by 397 is 7 with a remainder of 361.
The number 7 becomes the next digit in our result. 
Result so far: 32281.387
If we take 2779 away from 3140, we end up with 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Advancing to step 12:
3610 divided by 397 is 9 with a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 32281.3879
The remainder is 37 after subtracting 3573 from 3610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 13:
397 goes into 370 0 times with a remainder of 370.
The next digit of our result is 0. 
Result so far: 32281.3879
If we subtract 0 from 370, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Advancing to step 14:
When dividing 3700 by 397, we get 9 with a remainder of 127.
Write down 9 as next digit of the result. 
Result so far: 32281.387909
Subtracting 3573 from 3700 leaves us with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Moving on to step 15:
397 can be fit into 1270 3 times, resulting in a remainder of 79.
The next digit of our result is 3. 
Result so far: 32281.3879093
If we take 1191 away from 1270, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 16:
When dividing 790 by 397, we get 1 with a remainder of 393.
The next digit of our result is 1. 
Result so far: 32281.38790931
The remainder is 393 after subtracting 397 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

In conclusion, the division gives 32281.38790931 with a balance of 3.93e-07.
