12280317 divided by 311 
We're looking to find how many times 311 goes into 12280317.

Advancing to step 1:
311 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 311

Step 2:
When dividing 12 by 311, we get 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 311

On to step 3:
The number 311 fits into 122 0 times, leaving a remainder of 122.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 122 to get 122.
Bring next digit (8) of the dividend behind the 122 and repeat the process: 1228 / 311

Advancing to step 4:
When dividing 1228 by 311, we get 3 with a remainder of 295.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 933 from 1228 leaves us with 295.
Take the next digit (0) from the dividend and append it to 295, then repeat: 2950 / 311

Let's proceed to step 5:
311 can be fit into 2950 9 times, resulting in a remainder of 151.
Use 9 as the next digit of our solution. 
Result so far: 39.0
Subtract 2799 from 2950 to get 151.
Fetch the next digit (3) from the dividend, attach it to 151 and continue: 1513 / 311

Advancing to step 6:
311 can be fit into 1513 4 times, resulting in a remainder of 269.
The next digit of our result is 4. 
Result so far: 394.0
The remainder is 269 after subtracting 1244 from 1513.
Grab the next digit (1) from the dividend, add it to 269, then carry on: 2691 / 311

On to step 7:
311 can be fit into 2691 8 times, resulting in a remainder of 203.
The number 8 becomes the next digit in our result. 
Result so far: 3948.0
If we subtract 2488 from 2691, we get 203.
Fetch the next digit (7) from the dividend, attach it to 203 and continue: 2037 / 311

Step 8:
If we divide 2037 by 311, we get 6 and a remainder of 171.
The number 6 becomes the next digit in our result. 
Result so far: 39486.0
Deduct 1866 from 2037 and we're left with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Step 9:
When dividing 1710 by 311, we get 5 with a remainder of 155.
Use 5 as the next digit of our solution. 
Result so far: 39486.5
The remainder is 155 after subtracting 1555 from 1710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Advancing to step 10:
1550 divided by 311 is 4 with a remainder of 306.
Put 4 as the next digit of the answer. 
Result so far: 39486.54
The remainder is 306 after subtracting 1244 from 1550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Going ahead to step 11:
311 goes into 3060 9 times with a remainder of 261.
Record the quotient 9 as the next digit in the result. 
Result so far: 39486.549
If we take 2799 away from 3060, we end up with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Step 12:
311 can be fit into 2610 8 times, resulting in a remainder of 122.
Put 8 as the next digit of the answer. 
Result so far: 39486.5498
The remainder is 122 after subtracting 2488 from 2610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Step 13:
When dividing 1220 by 311, we get 3 with a remainder of 287.
The number 3 becomes the next digit in our result. 
Result so far: 39486.54983
Subtracting 933 from 1220 leaves us with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

On to step 14:
The number 311 fits into 2870 9 times, leaving a remainder of 71.
The number 9 becomes the next digit in our result. 
Result so far: 39486.549839
If we take 2799 away from 2870, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 15:
311 goes into 710 2 times with a remainder of 88.
The number 2 becomes the next digit in our result. 
Result so far: 39486.5498392
If we take 622 away from 710, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 16:
311 can be fit into 880 2 times, resulting in a remainder of 258.
Put 2 as the next digit of the answer. 
Result so far: 39486.54983922
The remainder is 258 after subtracting 622 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

In conclusion, the division gives 39486.54983922 with a balance of 2.58e-07.
