We look at the division of 82429138 by 255 
The aim is to understand the frequency of 255 in 82429138.

Step 1:
The number 255 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 255

Let's proceed to step 2:
255 can be fit into 82 0 times, resulting in a remainder of 82.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 82 to get 82.
Fetch the next digit (4) from the dividend, attach it to 82 and continue: 824 / 255

Moving on to step 3:
255 can be fit into 824 3 times, resulting in a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 765 from 824, we get 59.
Bring next digit (2) of the dividend behind the 59 and repeat the process: 592 / 255

Going ahead to step 4:
592 divided by 255 is 2 with a remainder of 82.
The next digit of our result is 2. 
Result so far: 32.0
Deduct 510 from 592 and we're left with 82.
Take the next digit (9) from the dividend and append it to 82, then repeat: 829 / 255

Step 5:
If we divide 829 by 255, we get 3 and a remainder of 64.
Use 3 as the next digit of our solution. 
Result so far: 323.0
Subtracting 765 from 829 leaves us with 64.
Take the next digit (1) from the dividend and append it to 64, then repeat: 641 / 255

Moving on to step 6:
255 goes into 641 2 times with a remainder of 131.
The next digit of our result is 2. 
Result so far: 3232.0
Deduct 510 from 641 and we're left with 131.
Include the next digit (3) from the dividend after 131, then repeat: 1313 / 255

Going ahead to step 7:
1313 divided by 255 is 5 with a remainder of 38.
Record the quotient 5 as the next digit in the result. 
Result so far: 32325.0
The remainder is 38 after subtracting 1275 from 1313.
Fetch the next digit (8) from the dividend, attach it to 38 and continue: 388 / 255

Let's proceed to step 8:
388 divided by 255 is 1 with a remainder of 133.
Record the quotient 1 as the next digit in the result. 
Result so far: 323251.0
Subtracting 255 from 388 leaves us with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

On to step 9:
255 can be fit into 1330 5 times, resulting in a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 323251.5
The remainder is 55 after subtracting 1275 from 1330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 10:
When dividing 550 by 255, we get 2 with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 323251.52
Subtract 510 from 550 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
If we divide 400 by 255, we get 1 and a remainder of 145.
Record the quotient 1 as the next digit in the result. 
Result so far: 323251.521
If we take 255 away from 400, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Advancing to step 12:
The number 255 fits into 1450 5 times, leaving a remainder of 175.
Put 5 as the next digit of the answer. 
Result so far: 323251.5215
If we take 1275 away from 1450, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 13:
The number 255 fits into 1750 6 times, leaving a remainder of 220.
The next digit of our result is 6. 
Result so far: 323251.52156
The remainder is 220 after subtracting 1530 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 14:
2200 divided by 255 is 8 with a remainder of 160.
The number 8 becomes the next digit in our result. 
Result so far: 323251.521568
If we take 2040 away from 2200, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 15:
255 can be fit into 1600 6 times, resulting in a remainder of 70.
Record the quotient 6 as the next digit in the result. 
Result so far: 323251.5215686
If we take 1530 away from 1600, we end up 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 16:
255 can be fit into 700 2 times, resulting in a remainder of 190.
Record the quotient 2 as the next digit in the result. 
Result so far: 323251.52156862
Subtract 510 from 700 to 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 final result is 323251.52156862 with a remainder of 1.9e-07.
