We look at the division of 31308 by 23 
Let's see how many times 23 fits into 31308.

On to step 1:
The number 23 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 23

Moving on to step 2:
31 divided by 23 is 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 23 from 31, we get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 23

Moving on to step 3:
The number 23 fits into 83 3 times, leaving a remainder of 14.
The next digit of our result is 3. 
Result so far: 13.0
The remainder is 14 after subtracting 69 from 83.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 23

On to step 4:
23 goes into 140 6 times with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 136.0
Subtracting 138 from 140 leaves us with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 23

Going ahead to step 5:
When dividing 28 by 23, we get 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1361.0
Deduct 23 from 28 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 6:
23 can be fit into 50 2 times, resulting in a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 1361.2
The remainder is 4 after subtracting 46 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
23 goes into 40 1 times with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1361.21
If we subtract 23 from 40, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 8:
23 can be fit into 170 7 times, resulting in a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 1361.217
If we subtract 161 from 170, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
23 can be fit into 90 3 times, resulting in a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 1361.2173
The remainder is 21 after subtracting 69 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 10:
If we divide 210 by 23, we get 9 and a remainder of 3.
The next digit of our result is 9. 
Result so far: 1361.21739
Subtracting 207 from 210 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 11:
When dividing 30 by 23, we get 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1361.217391
Subtract 23 from 30 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 12:
If we divide 70 by 23, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 1361.2173913
Subtracting 69 from 70 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 13:
If we divide 10 by 23, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1361.2173913
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 1361.2173913 with a remaining 1e-08.
