28859132 divided by 255 
The aim is to understand the frequency of 255 in 28859132.

On to step 1:
255 goes into 2 0 times with 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.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 255

On to step 2:
The number 255 fits into 28 0 times, leaving a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Grab the next digit (8) from the dividend, add it to 28, then carry on: 288 / 255

Let's proceed to step 3:
When dividing 288 by 255, we get 1 with a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 255 from 288 to get 33.
Include the next digit (5) from the dividend after 33, then repeat: 335 / 255

On to step 4:
When dividing 335 by 255, we get 1 with a remainder of 80.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 255 from 335 and we're left with 80.
Take the next digit (9) from the dividend and append it to 80, then repeat: 809 / 255

Advancing to step 5:
255 can be fit into 809 3 times, resulting in a remainder of 44.
The next digit of our result is 3. 
Result so far: 113.0
Subtract 765 from 809 to get 44.
Grab the next digit (1) from the dividend, add it to 44, then carry on: 441 / 255

Going ahead to step 6:
When dividing 441 by 255, we get 1 with a remainder of 186.
Put 1 as the next digit of the answer. 
Result so far: 1131.0
If we take 255 away from 441, we end up with 186.
Grab the next digit (3) from the dividend, add it to 186, then carry on: 1863 / 255

Step 7:
The number 255 fits into 1863 7 times, leaving a remainder of 78.
Put 7 as the next digit of the answer. 
Result so far: 11317.0
The remainder is 78 after subtracting 1785 from 1863.
Bring next digit (2) of the dividend behind the 78 and repeat the process: 782 / 255

Let's proceed to step 8:
255 can be fit into 782 3 times, resulting in a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 113173.0
Subtract 765 from 782 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 9:
255 can be fit into 170 0 times, resulting in a remainder of 170.
The number 0 becomes the next digit in our result. 
Result so far: 113173.0
If we subtract 0 from 170, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 10:
If we divide 1700 by 255, we get 6 and a remainder of 170.
Use 6 as the next digit of our solution. 
Result so far: 113173.06
If we subtract 1530 from 1700, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 11:
If we divide 1700 by 255, we get 6 and a remainder of 170.
Put 6 as the next digit of the answer. 
Result so far: 113173.066
The remainder is 170 after subtracting 1530 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Our division results in 113173.066 with a remaining 0.017.
