We're dividing 42544576 by 255 
The aim is to understand the frequency of 255 in 42544576.

On to step 1:
The number 255 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 255

Step 2:
The number 255 fits into 42 0 times, leaving a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Fetch the next digit (5) from the dividend, attach it to 42 and continue: 425 / 255

Going ahead to step 3:
When dividing 425 by 255, we get 1 with a remainder of 170.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 255 from 425 and we're left with 170.
Fetch the next digit (4) from the dividend, attach it to 170 and continue: 1704 / 255

Going ahead to step 4:
255 can be fit into 1704 6 times, resulting in a remainder of 174.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtract 1530 from 1704 to get 174.
Include the next digit (4) from the dividend after 174, then repeat: 1744 / 255

Step 5:
The number 255 fits into 1744 6 times, leaving a remainder of 214.
Write down 6 as next digit of the result. 
Result so far: 166.0
The remainder is 214 after subtracting 1530 from 1744.
Include the next digit (5) from the dividend after 214, then repeat: 2145 / 255

Let's proceed to step 6:
2145 divided by 255 is 8 with a remainder of 105.
The number 8 becomes the next digit in our result. 
Result so far: 1668.0
Subtracting 2040 from 2145 leaves us with 105.
Take the next digit (7) from the dividend and append it to 105, then repeat: 1057 / 255

Step 7:
When dividing 1057 by 255, we get 4 with a remainder of 37.
Record the quotient 4 as the next digit in the result. 
Result so far: 16684.0
The remainder is 37 after subtracting 1020 from 1057.
Take the next digit (6) from the dividend and append it to 37, then repeat: 376 / 255

Advancing to step 8:
The number 255 fits into 376 1 times, leaving a remainder of 121.
Record the quotient 1 as the next digit in the result. 
Result so far: 166841.0
Subtracting 255 from 376 leaves us with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Moving on to step 9:
255 goes into 1210 4 times with a remainder of 190.
Use 4 as the next digit of our solution. 
Result so far: 166841.4
If we subtract 1020 from 1210, 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.

Advancing to step 10:
1900 divided by 255 is 7 with a remainder of 115.
Use 7 as the next digit of our solution. 
Result so far: 166841.47
Subtracting 1785 from 1900 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 11:
255 can be fit into 1150 4 times, resulting in a remainder of 130.
The number 4 becomes the next digit in our result. 
Result so far: 166841.474
Subtracting 1020 from 1150 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 12:
255 can be fit into 1300 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 166841.4745
If we subtract 1275 from 1300, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 13:
250 divided by 255 is 0 with a remainder of 250.
The next digit of our result is 0. 
Result so far: 166841.4745
If we subtract 0 from 250, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 14:
255 goes into 2500 9 times with a remainder of 205.
Record the quotient 9 as the next digit in the result. 
Result so far: 166841.474509
Subtracting 2295 from 2500 leaves us with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Step 15:
If we divide 2050 by 255, we get 8 and a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 166841.4745098
Subtracting 2040 from 2050 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 16:
When dividing 100 by 255, we get 0 with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 166841.4745098
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 166841.4745098 and a remainder of 1e-07.
