Let's divide 12662349 by 312
Our goal is to divide 12662349 by 312.

Step 1:
1 divided by 312 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 312

On to step 2:
312 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 312

Let's proceed to step 3:
312 can be fit into 126 0 times, resulting in a remainder of 126.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 126 leaves us with 126.
Bring next digit (6) of the dividend behind the 126 and repeat the process: 1266 / 312

Moving on to step 4:
312 goes into 1266 4 times with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 1248 away from 1266, we end up with 18.
Grab the next digit (2) from the dividend, add it to 18, then carry on: 182 / 312

Advancing to step 5:
312 can be fit into 182 0 times, resulting in a remainder of 182.
Write down 0 as next digit of the result. 
Result so far: 40.0
If we subtract 0 from 182, we get 182.
Fetch the next digit (3) from the dividend, attach it to 182 and continue: 1823 / 312

Going ahead to step 6:
312 goes into 1823 5 times with a remainder of 263.
The next digit of our result is 5. 
Result so far: 405.0
Deduct 1560 from 1823 and we're left with 263.
Include the next digit (4) from the dividend after 263, then repeat: 2634 / 312

Going ahead to step 7:
If we divide 2634 by 312, we get 8 and a remainder of 138.
The number 8 becomes the next digit in our result. 
Result so far: 4058.0
If we subtract 2496 from 2634, we get 138.
Take the next digit (9) from the dividend and append it to 138, then repeat: 1389 / 312

On to step 8:
The number 312 fits into 1389 4 times, leaving a remainder of 141.
Use 4 as the next digit of our solution. 
Result so far: 40584.0
If we subtract 1248 from 1389, we get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Moving on to step 9:
312 goes into 1410 4 times with a remainder of 162.
The next digit of our result is 4. 
Result so far: 40584.4
Subtracting 1248 from 1410 leaves us with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

On to step 10:
When dividing 1620 by 312, we get 5 with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 40584.45
If we take 1560 away from 1620, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
When dividing 600 by 312, we get 1 with a remainder of 288.
Put 1 as the next digit of the answer. 
Result so far: 40584.451
Subtracting 312 from 600 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.

Going ahead to step 12:
312 can be fit into 2880 9 times, resulting in a remainder of 72.
Use 9 as the next digit of our solution. 
Result so far: 40584.4519
Subtract 2808 from 2880 to get 72.
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 312 is 2 with a remainder of 96.
Record the quotient 2 as the next digit in the result. 
Result so far: 40584.45192
If we subtract 624 from 720, we 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 14:
960 divided by 312 is 3 with a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 40584.451923
Subtracting 936 from 960 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.

Moving on to step 15:
If we divide 240 by 312, we get 0 and a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 40584.451923
Subtracting 0 from 240 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 16:
312 can be fit into 2400 7 times, resulting in a remainder of 216.
The number 7 becomes the next digit in our result. 
Result so far: 40584.45192307
Deduct 2184 from 2400 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

In conclusion, the division gives 40584.45192307 with a balance of 2.16e-07.
