We look at the division of 264393 by 12 
Our goal is to divide 264393 by 12.

Step 1:
When dividing 2 by 12, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 12

On to step 2:
12 goes into 26 2 times with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 2 after subtracting 24 from 26.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 12

Step 3:
If we divide 24 by 12, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
If we subtract 24 from 24, we get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 12

Let's proceed to step 4:
12 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 220.0
If we subtract 0 from 3, we get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 12

Moving on to step 5:
When dividing 39 by 12, we get 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 2203.0
Subtracting 36 from 39 leaves us with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 12

Step 6:
12 goes into 33 2 times with a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 22032.0
Subtracting 24 from 33 leaves us 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.

Step 7:
If we divide 90 by 12, we get 7 and a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 22032.7
If we take 84 away from 90, we end up 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: 22032.75
Deduct 60 from 60 and we're left 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 9:
12 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 22032.75
The remainder is 0 after subtracting 0 from 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 10:
0 divided by 12 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 22032.75
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.

Our division results in 22032.75 with a remaining 0.0.
