We look at the division of 255262 by 12 
We're looking to find how many times 12 goes into 255262.

Advancing to step 1:
The number 12 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 12

Going ahead to step 2:
12 goes into 25 2 times with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 24 from 25 and we're left with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 12

Advancing to step 3:
12 can be fit into 15 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Deduct 12 from 15 and we're left with 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 12

Advancing to step 4:
When dividing 32 by 12, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 212.0
Subtracting 24 from 32 leaves us with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 12

Going ahead to step 5:
12 can be fit into 86 7 times, resulting in a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 2127.0
Subtract 84 from 86 to get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 12

Advancing to step 6:
If we divide 22 by 12, we get 1 and a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 21271.0
If we subtract 12 from 22, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
The number 12 fits into 100 8 times, leaving a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 21271.8
Subtracting 96 from 100 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
40 divided by 12 is 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 21271.83
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
When dividing 40 by 12, we get 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 21271.833
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 21271.833 with a remainder of 0.0004.
