We're dividing 43877033 by 255 
The aim is to understand the frequency of 255 in 43877033.

Step 1:
When dividing 4 by 255, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 255

Step 2:
When dividing 43 by 255, we get 0 with a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Append the next digit (8) from the dividend to 43 and continue with: 438 / 255

On to step 3:
If we divide 438 by 255, we get 1 and a remainder of 183.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 255 from 438 leaves us with 183.
Append the next digit (7) from the dividend to 183 and continue with: 1837 / 255

Going ahead to step 4:
The number 255 fits into 1837 7 times, leaving a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Deduct 1785 from 1837 and we're left with 52.
Grab the next digit (7) from the dividend, add it to 52, then carry on: 527 / 255

Step 5:
527 divided by 255 is 2 with a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 172.0
If we take 510 away from 527, we end up with 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 255

On to step 6:
If we divide 170 by 255, we get 0 and a remainder of 170.
The next digit of our result is 0. 
Result so far: 1720.0
Subtracting 0 from 170 leaves us with 170.
Include the next digit (3) from the dividend after 170, then repeat: 1703 / 255

Advancing to step 7:
The number 255 fits into 1703 6 times, leaving a remainder of 173.
The number 6 becomes the next digit in our result. 
Result so far: 17206.0
Subtract 1530 from 1703 to get 173.
Bring next digit (3) of the dividend behind the 173 and repeat the process: 1733 / 255

Let's proceed to step 8:
The number 255 fits into 1733 6 times, leaving a remainder of 203.
Put 6 as the next digit of the answer. 
Result so far: 172066.0
Subtracting 1530 from 1733 leaves us with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Going ahead to step 9:
255 can be fit into 2030 7 times, resulting in a remainder of 245.
The next digit of our result is 7. 
Result so far: 172066.7
If we subtract 1785 from 2030, we get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Let's proceed to step 10:
When dividing 2450 by 255, we get 9 with a remainder of 155.
The next digit of our result is 9. 
Result so far: 172066.79
If we take 2295 away from 2450, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Let's proceed to step 11:
If we divide 1550 by 255, we get 6 and a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 172066.796
If we subtract 1530 from 1550, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
255 can be fit into 200 0 times, resulting in a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 172066.796
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 13:
When dividing 2000 by 255, we get 7 with a remainder of 215.
The next digit of our result is 7. 
Result so far: 172066.79607
The remainder is 215 after subtracting 1785 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Advancing to step 14:
If we divide 2150 by 255, we get 8 and a remainder of 110.
Use 8 as the next digit of our solution. 
Result so far: 172066.796078
If we subtract 2040 from 2150, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 15:
255 goes into 1100 4 times with a remainder of 80.
The number 4 becomes the next digit in our result. 
Result so far: 172066.7960784
If we take 1020 away from 1100, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 16:
800 divided by 255 is 3 with a remainder of 35.
Put 3 as the next digit of the answer. 
Result so far: 172066.79607843
If we subtract 765 from 800, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 172066.79607843 with a remainder of 3.5e-08.
