We divide 71542273 by 255
The aim is to understand the frequency of 255 in 71542273.

On to step 1:
If we divide 7 by 255, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 255

Moving on to step 2:
71 divided by 255 is 0 with a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Include the next digit (5) from the dividend after 71, then repeat: 715 / 255

On to step 3:
255 goes into 715 2 times with a remainder of 205.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 510 from 715, we get 205.
Grab the next digit (4) from the dividend, add it to 205, then carry on: 2054 / 255

Going ahead to step 4:
2054 divided by 255 is 8 with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 28.0
Deduct 2040 from 2054 and we're left with 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 255

On to step 5:
255 can be fit into 142 0 times, resulting in a remainder of 142.
The next digit of our result is 0. 
Result so far: 280.0
Subtracting 0 from 142 leaves us with 142.
Take the next digit (2) from the dividend and append it to 142, then repeat: 1422 / 255

Let's proceed to step 6:
If we divide 1422 by 255, we get 5 and a remainder of 147.
Put 5 as the next digit of the answer. 
Result so far: 2805.0
Deduct 1275 from 1422 and we're left with 147.
Grab the next digit (7) from the dividend, add it to 147, then carry on: 1477 / 255

Step 7:
255 can be fit into 1477 5 times, resulting in a remainder of 202.
Put 5 as the next digit of the answer. 
Result so far: 28055.0
If we take 1275 away from 1477, we end up with 202.
Fetch the next digit (3) from the dividend, attach it to 202 and continue: 2023 / 255

Advancing to step 8:
The number 255 fits into 2023 7 times, leaving a remainder of 238.
The next digit of our result is 7. 
Result so far: 280557.0
If we subtract 1785 from 2023, we get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

On to step 9:
255 can be fit into 2380 9 times, resulting in a remainder of 85.
The number 9 becomes the next digit in our result. 
Result so far: 280557.9
If we take 2295 away from 2380, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 10:
The number 255 fits into 850 3 times, leaving a remainder of 85.
Use 3 as the next digit of our solution. 
Result so far: 280557.93
Subtracting 765 from 850 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 11:
850 divided by 255 is 3 with a remainder of 85.
Record the quotient 3 as the next digit in the result. 
Result so far: 280557.933
Deduct 765 from 850 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Our division results in 280557.933 with a remaining 0.0085.
