We divide 43855 by 31
Our goal is to divide 43855 by 31.

On to step 1:
31 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 31

Advancing to step 2:
When dividing 43 by 31, we get 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 31 from 43, we get 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 31

On to step 3:
31 goes into 128 4 times with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtracting 124 from 128 leaves us with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 31

On to step 4:
31 goes into 45 1 times with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 141.0
Subtracting 31 from 45 leaves us with 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 31

Moving on to step 5:
31 can be fit into 145 4 times, resulting in a remainder of 21.
The next digit of our result is 4. 
Result so far: 1414.0
Subtract 124 from 145 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 6:
210 divided by 31 is 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 1414.6
Subtract 186 from 210 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 7:
31 can be fit into 240 7 times, resulting in a remainder of 23.
The next digit of our result is 7. 
Result so far: 1414.67
The remainder is 23 after subtracting 217 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 8:
31 can be fit into 230 7 times, resulting in a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 1414.677
The remainder is 13 after subtracting 217 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 1414.677 with a remainder of 0.0013.
