We're dividing 5435664 by 255 
The aim is to understand the frequency of 255 in 5435664.

Step 1:
When dividing 5 by 255, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 255

Going ahead to step 2:
The number 255 fits into 54 0 times, leaving a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 54 after subtracting 0 from 54.
Fetch the next digit (3) from the dividend, attach it to 54 and continue: 543 / 255

Moving on to step 3:
The number 255 fits into 543 2 times, leaving a remainder of 33.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 510 from 543 to get 33.
Grab the next digit (5) from the dividend, add it to 33, then carry on: 335 / 255

Going ahead to step 4:
255 can be fit into 335 1 times, resulting in a remainder of 80.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we take 255 away from 335, we end up with 80.
Grab the next digit (6) from the dividend, add it to 80, then carry on: 806 / 255

Let's proceed to step 5:
806 divided by 255 is 3 with a remainder of 41.
Put 3 as the next digit of the answer. 
Result so far: 213.0
The remainder is 41 after subtracting 765 from 806.
Fetch the next digit (6) from the dividend, attach it to 41 and continue: 416 / 255

Going ahead to step 6:
When dividing 416 by 255, we get 1 with a remainder of 161.
The next digit of our result is 1. 
Result so far: 2131.0
Deduct 255 from 416 and we're left with 161.
Take the next digit (4) from the dividend and append it to 161, then repeat: 1614 / 255

Let's proceed to step 7:
The number 255 fits into 1614 6 times, leaving a remainder of 84.
Record the quotient 6 as the next digit in the result. 
Result so far: 21316.0
The remainder is 84 after subtracting 1530 from 1614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 8:
When dividing 840 by 255, we get 3 with a remainder of 75.
The next digit of our result is 3. 
Result so far: 21316.3
If we subtract 765 from 840, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 9:
750 divided by 255 is 2 with a remainder of 240.
Write down 2 as next digit of the result. 
Result so far: 21316.32
Subtracting 510 from 750 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 10:
255 can be fit into 2400 9 times, resulting in a remainder of 105.
Write down 9 as next digit of the result. 
Result so far: 21316.329
If we subtract 2295 from 2400, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 11:
255 goes into 1050 4 times with a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 21316.3294
If we subtract 1020 from 1050, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
If we divide 300 by 255, we get 1 and a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 21316.32941
Subtracting 255 from 300 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 13:
When dividing 450 by 255, we get 1 with a remainder of 195.
The number 1 becomes the next digit in our result. 
Result so far: 21316.329411
Subtract 255 from 450 to get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

After the division, we end up with 21316.329411 and a remainder of 1.95e-05.
