255 can be fit into 66 0 times, resulting in a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Fetch the next digit (8) from the dividend, attach it to 66 and continue: 668 / 255

On to step 3:
The number 255 fits into 668 2 times, leaving a remainder of 158.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 510 from 668 to get 158.
Fetch the next digit (0) from the dividend, attach it to 158 and continue: 1580 / 255

Let's proceed to step 4:
255 goes into 1580 6 times with a remainder of 50.
The next digit of our result is 6. 
Result so far: 26.0
Deduct 1530 from 1580 and we're left with 50.

Moving on to step 5:
509 divided by 255 is 1 with a remainder of 254.
Use 1 as the next digit of our solution. 
Result so far: 261.0
Subtracting 255 from 509 leaves us with 254.
Include the next digit (7) from the dividend after 254, then repeat: 2547 / 255

Going ahead to step 6:
The number 255 fits into 2547 9 times, leaving a remainder of 252.
Record the quotient 9 as the next digit in the result. 
Result so far: 2619.0
Subtracting 2295 from 2547 leaves us with 252.
Include the next digit (5) from the dividend after 252, then repeat: 2525 / 255

Step 7:
2525 divided by 255 is 9 with a remainder of 230.
The next digit of our result is 9. 
Result so far: 26199.0
Subtracting 2295 from 2525 leaves us with 230.
Include the next digit (6) from the dividend after 230, then repeat: 2306 / 255

On to step 8:
2306 divided by 255 is 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 261999.0
Subtracting 2295 from 2306 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
255 goes into 110 0 times with a remainder of 110.
Use 0 as the next digit of our solution. 
Result so far: 261999.0
If we subtract 0 from 110, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 10:
255 goes into 1100 4 times with a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 261999.04
Subtract 1020 from 1100 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 11:
255 can be fit into 800 3 times, resulting in a remainder of 35.
Put 3 as the next digit of the answer. 
Result so far: 261999.043
Deduct 765 from 800 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 12:
255 goes into 350 1 times with a remainder of 95.
Use 1 as the next digit of our solution. 
Result so far: 261999.0431
The remainder is 95 after subtracting 255 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Advancing to step 13:
If we divide 950 by 255, we get 3 and a remainder of 185.
The number 3 becomes the next digit in our result. 
Result so far: 261999.04313
The remainder is 185 after subtracting 765 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Step 14:
255 can be fit into 1850 7 times, resulting in a remainder of 65.
Put 7 as the next digit of the answer. 
Result so far: 261999.043137
The remainder is 65 after subtracting 1785 from 1850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 15:
255 goes into 650 2 times with a remainder of 140.
Record the quotient 2 as the next digit in the result. 
Result so far: 261999.0431372
Deduct 510 from 650 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 16:
255 goes into 1400 5 times with a remainder of 125.
The number 5 becomes the next digit in our result. 
Result so far: 261999.04313725
If we subtract 1275 from 1400, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

The quotient of the division is 261999.04313725, and the remainder is 1.25e-07.
