We divide 142331 by 31
We want to figure out the number of times 142331 can be divided by 31.

On to step 1:
31 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 31

Let's proceed to step 2:
31 goes into 14 0 times with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 31

Let's proceed to step 3:
31 can be fit into 142 4 times, resulting in a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 124 from 142 and we're left with 18.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 31

Advancing to step 4:
The number 31 fits into 183 5 times, leaving a remainder of 28.
Write down 5 as next digit of the result. 
Result so far: 45.0
If we subtract 155 from 183, we get 28.
Take the next digit (3) from the dividend and append it to 28, then repeat: 283 / 31

Moving on to step 5:
31 can be fit into 283 9 times, resulting in a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 459.0
If we take 279 away from 283, we end up with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 31

Advancing to step 6:
31 can be fit into 41 1 times, resulting in a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 4591.0
Subtract 31 from 41 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
When dividing 100 by 31, we get 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 4591.3
Subtracting 93 from 100 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
70 divided by 31 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 4591.32
The remainder is 8 after subtracting 62 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
The number 31 fits into 80 2 times, leaving a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 4591.322
Subtract 62 from 80 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 4591.322 with a remaining 0.0018.
