We're dividing 231393 by 12 
Our goal is to divide 231393 by 12.

Moving on to step 1:
2 divided by 12 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 12

Going ahead to step 2:
If we divide 23 by 12, we get 1 and a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 12 from 23, we get 11.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 12

Advancing to step 3:
111 divided by 12 is 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Deduct 108 from 111 and we're left with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 12

On to step 4:
12 can be fit into 33 2 times, resulting in a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 192.0
Subtract 24 from 33 to get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 12

Let's proceed to step 5:
12 can be fit into 99 8 times, resulting in a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 1928.0
Deduct 96 from 99 and we're left with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 12

Let's proceed to step 6:
When dividing 33 by 12, we get 2 with a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 19282.0
The remainder is 9 after subtracting 24 from 33.
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 7:
If we divide 90 by 12, we get 7 and a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 19282.7
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.

Step 8:
The number 12 fits into 60 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 19282.75
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.

On to step 9:
0 divided by 12 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 19282.75
If we take 0 away from 0, we end up 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.

Step 10:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 19282.75
Subtract 0 from 0 to 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.

The final outcome is 19282.75, with a leftover of 0.0.
