255325 ÷ 28 
The aim is to understand the frequency of 28 in 255325.

Step 1:
28 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 28

Moving on to step 2:
The number 28 fits into 25 0 times, leaving a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Bring next digit (5) of the dividend behind the 25 and repeat the process: 255 / 28

Going ahead to step 3:
If we divide 255 by 28, we get 9 and a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 252 from 255 leaves us with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 28

Let's proceed to step 4:
28 goes into 33 1 times with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
Subtracting 28 from 33 leaves us with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 28

Advancing to step 5:
The number 28 fits into 52 1 times, leaving a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 911.0
The remainder is 24 after subtracting 28 from 52.
Grab the next digit (5) from the dividend, add it to 24, then carry on: 245 / 28

Step 6:
The number 28 fits into 245 8 times, leaving a remainder of 21.
Write down 8 as next digit of the result. 
Result so far: 9118.0
Deduct 224 from 245 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 7:
When dividing 210 by 28, we get 7 with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 9118.7
If we take 196 away from 210, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
28 goes into 140 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 9118.75
Subtracting 140 from 140 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
When dividing 0 by 28, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9118.75
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
28 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 9118.75
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 9118.75 with a remainder of 0.0.
