Let's divide 255 by 66
We want to figure out the number of times 255 can be divided by 66.

On to step 1:
2 divided by 66 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 66

Moving on to step 2:
If we divide 25 by 66, we get 0 and a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Fetch the next digit (5) from the dividend, attach it to 25 and continue: 255 / 66

Going ahead to step 3:
The number 66 fits into 255 3 times, leaving a remainder of 57.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 198 away from 255, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 4:
When dividing 570 by 66, we get 8 with a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 3.8
Subtract 528 from 570 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 5:
The number 66 fits into 420 6 times, leaving a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 3.86
Subtract 396 from 420 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 6:
The number 66 fits into 240 3 times, leaving a remainder of 42.
The next digit of our result is 3. 
Result so far: 3.863
Deduct 198 from 240 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 7:
66 goes into 420 6 times with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 3.8636
Deduct 396 from 420 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
66 goes into 240 3 times with a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 3.86363
The remainder is 42 after subtracting 198 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 9:
If we divide 420 by 66, we get 6 and a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 3.863636
If we subtract 396 from 420, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 10:
The number 66 fits into 240 3 times, leaving a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 3.8636363
If we take 198 away from 240, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 11:
420 divided by 66 is 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 3.86363636
Deduct 396 from 420 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 3.86363636 with a balance of 2.4e-08.
