9491158 divided by 255 
The aim is to understand the frequency of 255 in 9491158.

Going ahead to step 1:
When dividing 9 by 255, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 255

Moving on to step 2:
The number 255 fits into 94 0 times, leaving a remainder of 94.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 94 and we're left with 94.
Include the next digit (9) from the dividend after 94, then repeat: 949 / 255

Moving on to step 3:
The number 255 fits into 949 3 times, leaving a remainder of 184.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 765 from 949 and we're left with 184.
Take the next digit (1) from the dividend and append it to 184, then repeat: 1841 / 255

Let's proceed to step 4:
255 can be fit into 1841 7 times, resulting in a remainder of 56.
Put 7 as the next digit of the answer. 
Result so far: 37.0
If we take 1785 away from 1841, we end up with 56.
Take the next digit (1) from the dividend and append it to 56, then repeat: 561 / 255

On to step 5:
255 can be fit into 561 2 times, resulting in a remainder of 51.
The number 2 becomes the next digit in our result. 
Result so far: 372.0
Subtracting 510 from 561 leaves us with 51.
Take the next digit (5) from the dividend and append it to 51, then repeat: 515 / 255

Moving on to step 6:
The number 255 fits into 515 2 times, leaving a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 3722.0
If we take 510 away from 515, we end up with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 255

Let's proceed to step 7:
When dividing 58 by 255, we get 0 with a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 37220.0
Subtract 0 from 58 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 8:
If we divide 580 by 255, we get 2 and a remainder of 70.
The next digit of our result is 2. 
Result so far: 37220.2
Deduct 510 from 580 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 9:
If we divide 700 by 255, we get 2 and a remainder of 190.
The number 2 becomes the next digit in our result. 
Result so far: 37220.22
If we subtract 510 from 700, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

The quotient of the division is 37220.22, and the remainder is 0.19.
