13943521 divided by 311 
We want to divide 13943521 by 311.

Going ahead to step 1:
If we divide 1 by 311, we get 0 and 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 (3) from the dividend after 1, then repeat: 13 / 311

Step 2:
13 divided by 311 is 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 311

On to step 3:
311 goes into 139 0 times with a remainder of 139.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 139 after subtracting 0 from 139.
Append the next digit (4) from the dividend to 139 and continue with: 1394 / 311

On to step 4:
311 can be fit into 1394 4 times, resulting in a remainder of 150.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 1244 from 1394 leaves us with 150.
Take the next digit (3) from the dividend and append it to 150, then repeat: 1503 / 311

Step 5:
If we divide 1503 by 311, we get 4 and a remainder of 259.
Write down 4 as next digit of the result. 
Result so far: 44.0
Deduct 1244 from 1503 and we're left with 259.
Grab the next digit (5) from the dividend, add it to 259, then carry on: 2595 / 311

Let's proceed to step 6:
311 goes into 2595 8 times with a remainder of 107.
Record the quotient 8 as the next digit in the result. 
Result so far: 448.0
Subtracting 2488 from 2595 leaves us with 107.
Grab the next digit (2) from the dividend, add it to 107, then carry on: 1072 / 311

Step 7:
If we divide 1072 by 311, we get 3 and a remainder of 139.
Use 3 as the next digit of our solution. 
Result so far: 4483.0
Subtract 933 from 1072 to get 139.
Bring next digit (1) of the dividend behind the 139 and repeat the process: 1391 / 311

On to step 8:
If we divide 1391 by 311, we get 4 and a remainder of 147.
The number 4 becomes the next digit in our result. 
Result so far: 44834.0
If we take 1244 away from 1391, we end up with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Step 9:
311 goes into 1470 4 times with a remainder of 226.
Record the quotient 4 as the next digit in the result. 
Result so far: 44834.4
Subtracting 1244 from 1470 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Moving on to step 10:
If we divide 2260 by 311, we get 7 and a remainder of 83.
The next digit of our result is 7. 
Result so far: 44834.47
If we take 2177 away from 2260, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 11:
311 goes into 830 2 times with a remainder of 208.
The next digit of our result is 2. 
Result so far: 44834.472
If we subtract 622 from 830, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Going ahead to step 12:
The number 311 fits into 2080 6 times, leaving a remainder of 214.
Put 6 as the next digit of the answer. 
Result so far: 44834.4726
If we take 1866 away from 2080, we end up with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Let's proceed to step 13:
2140 divided by 311 is 6 with a remainder of 274.
Record the quotient 6 as the next digit in the result. 
Result so far: 44834.47266
Deduct 1866 from 2140 and we're left with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

The final outcome is 44834.47266, with a leftover of 0.000274.
