We're dividing 4391871 by 311 
We're looking to find how many times 311 goes into 4391871.

On to step 1:
311 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 311

Going ahead to step 2:
When dividing 43 by 311, we get 0 with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 311

On to step 3:
If we divide 439 by 311, we get 1 and a remainder of 128.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 311 from 439 and we're left with 128.
Fetch the next digit (1) from the dividend, attach it to 128 and continue: 1281 / 311

On to step 4:
1281 divided by 311 is 4 with a remainder of 37.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtract 1244 from 1281 to get 37.
Grab the next digit (8) from the dividend, add it to 37, then carry on: 378 / 311

Advancing to step 5:
The number 311 fits into 378 1 times, leaving a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 141.0
Subtracting 311 from 378 leaves us with 67.
Grab the next digit (7) from the dividend, add it to 67, then carry on: 677 / 311

On to step 6:
If we divide 677 by 311, we get 2 and a remainder of 55.
Write down 2 as next digit of the result. 
Result so far: 1412.0
If we subtract 622 from 677, we get 55.
Take the next digit (1) from the dividend and append it to 55, then repeat: 551 / 311

Moving on to step 7:
311 can be fit into 551 1 times, resulting in a remainder of 240.
Write down 1 as next digit of the result. 
Result so far: 14121.0
Subtracting 311 from 551 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.

Advancing to step 8:
311 goes into 2400 7 times with a remainder of 223.
The next digit of our result is 7. 
Result so far: 14121.7
Subtracting 2177 from 2400 leaves us with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Moving on to step 9:
When dividing 2230 by 311, we get 7 with a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 14121.77
The remainder is 53 after subtracting 2177 from 2230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

The quotient of the division is 14121.77, and the remainder is 0.053.
