We're dividing 12240606 by 311 
We want to divide 12240606 by 311.

Going ahead to step 1:
311 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 311

On to step 2:
The number 311 fits into 12 0 times, leaving a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 311

Advancing to step 3:
122 divided by 311 is 0 with a remainder of 122.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 122 to get 122.
Include the next digit (4) from the dividend after 122, then repeat: 1224 / 311

Step 4:
1224 divided by 311 is 3 with a remainder of 291.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 291 after subtracting 933 from 1224.
Bring next digit (0) of the dividend behind the 291 and repeat the process: 2910 / 311

Advancing to step 5:
2910 divided by 311 is 9 with a remainder of 111.
Put 9 as the next digit of the answer. 
Result so far: 39.0
Subtracting 2799 from 2910 leaves us with 111.
Take the next digit (6) from the dividend and append it to 111, then repeat: 1116 / 311

Step 6:
311 goes into 1116 3 times with a remainder of 183.
The next digit of our result is 3. 
Result so far: 393.0
Subtracting 933 from 1116 leaves us with 183.
Take the next digit (0) from the dividend and append it to 183, then repeat: 1830 / 311

Going ahead to step 7:
When dividing 1830 by 311, we get 5 with a remainder of 275.
Write down 5 as next digit of the result. 
Result so far: 3935.0
Subtracting 1555 from 1830 leaves us with 275.
Bring next digit (6) of the dividend behind the 275 and repeat the process: 2756 / 311

Moving on to step 8:
When dividing 2756 by 311, we get 8 with a remainder of 268.
Put 8 as the next digit of the answer. 
Result so far: 39358.0
Subtract 2488 from 2756 to get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Advancing to step 9:
311 goes into 2680 8 times with a remainder of 192.
Write down 8 as next digit of the result. 
Result so far: 39358.8
If we subtract 2488 from 2680, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 10:
When dividing 1920 by 311, we get 6 with a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 39358.86
If we take 1866 away from 1920, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 11:
540 divided by 311 is 1 with a remainder of 229.
The next digit of our result is 1. 
Result so far: 39358.861
Subtract 311 from 540 to get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Going ahead to step 12:
When dividing 2290 by 311, we get 7 with a remainder of 113.
Use 7 as the next digit of our solution. 
Result so far: 39358.8617
Subtract 2177 from 2290 to get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

On to step 13:
When dividing 1130 by 311, we get 3 with a remainder of 197.
Write down 3 as next digit of the result. 
Result so far: 39358.86173
Subtracting 933 from 1130 leaves us with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Step 14:
The number 311 fits into 1970 6 times, leaving a remainder of 104.
The number 6 becomes the next digit in our result. 
Result so far: 39358.861736
If we subtract 1866 from 1970, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 15:
311 goes into 1040 3 times with a remainder of 107.
The next digit of our result is 3. 
Result so far: 39358.8617363
Subtracting 933 from 1040 leaves us with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Going ahead to step 16:
If we divide 1070 by 311, we get 3 and a remainder of 137.
The number 3 becomes the next digit in our result. 
Result so far: 39358.86173633
Subtract 933 from 1070 to get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

After the division, we end up with 39358.86173633 and a remainder of 1.37e-07.
