We look at the division of 31246 by 23 
Let's see how many times 23 fits into 31246.

On to step 1:
If we divide 3 by 23, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 23

Advancing to step 2:
23 goes into 31 1 times with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 23 from 31 and we're left with 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 23

Going ahead to step 3:
The number 23 fits into 82 3 times, leaving a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 69 from 82, we get 13.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 23

Moving on to step 4:
If we divide 134 by 23, we get 5 and a remainder of 19.
Use 5 as the next digit of our solution. 
Result so far: 135.0
Subtract 115 from 134 to get 19.
Include the next digit (6) from the dividend after 19, then repeat: 196 / 23

Advancing to step 5:
23 can be fit into 196 8 times, resulting in a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 1358.0
Subtracting 184 from 196 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 6:
The number 23 fits into 120 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 1358.5
Deduct 115 from 120 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 7:
If we divide 50 by 23, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 1358.52
Subtract 46 from 50 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
If we divide 40 by 23, we get 1 and a remainder of 17.
The next digit of our result is 1. 
Result so far: 1358.521
Subtract 23 from 40 to 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.

Advancing to step 9:
170 divided by 23 is 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 1358.5217
Deduct 161 from 170 and we're left with 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 10:
The number 23 fits into 90 3 times, leaving a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 1358.52173
If we take 69 away from 90, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 11:
23 can be fit into 210 9 times, resulting in a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 1358.521739
The remainder is 3 after subtracting 207 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 12:
The number 23 fits into 30 1 times, leaving a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1358.5217391
If we take 23 away from 30, we end up 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 13:
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: 1358.52173913
If we take 69 away from 70, we end up 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.

The quotient of the division is 1358.52173913, and the remainder is 1e-09.
