We look at the division of 31110 by 86 
We want to figure out the number of times 31110 can be divided by 86.

Going ahead to step 1:
86 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 86

Step 2:
86 goes into 31 0 times with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Take the next digit (1) from the dividend and append it to 31, then repeat: 311 / 86

Going ahead to step 3:
311 divided by 86 is 3 with a remainder of 53.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 53 after subtracting 258 from 311.
Fetch the next digit (1) from the dividend, attach it to 53 and continue: 531 / 86

Going ahead to step 4:
If we divide 531 by 86, we get 6 and a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
Deduct 516 from 531 and we're left with 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 86

Step 5:
When dividing 150 by 86, we get 1 with a remainder of 64.
Record the quotient 1 as the next digit in the result. 
Result so far: 361.0
If we subtract 86 from 150, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 6:
If we divide 640 by 86, we get 7 and a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 361.7
Deduct 602 from 640 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 7:
If we divide 380 by 86, we get 4 and a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 361.74
If we take 344 away from 380, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 8:
The number 86 fits into 360 4 times, leaving a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 361.744
Subtract 344 from 360 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 361.744 with a remaining 0.0016.
