231513 ÷ 12 
Our goal is to divide 231513 by 12.

On to step 1:
12 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 12

Moving on to step 2:
When dividing 23 by 12, we get 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 12 from 23 to get 11.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 12

Advancing to step 3:
The number 12 fits into 111 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtract 108 from 111 to get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 12

Let's proceed to step 4:
35 divided by 12 is 2 with a remainder of 11.
The next digit of our result is 2. 
Result so far: 192.0
The remainder is 11 after subtracting 24 from 35.
Append the next digit (1) from the dividend to 11 and continue with: 111 / 12

Going ahead to step 5:
12 can be fit into 111 9 times, resulting in a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 1929.0
Subtract 108 from 111 to get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 12

Going ahead to step 6:
12 can be fit into 33 2 times, resulting in a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 19292.0
If we subtract 24 from 33, 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.

Step 7:
When dividing 90 by 12, we get 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 19292.7
Deduct 84 from 90 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
When dividing 60 by 12, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 19292.75
If we subtract 60 from 60, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 19292.75
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
The number 12 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 19292.75
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 19292.75 with a remainder of 0.0.
