We divide 67646147 by 255
The aim is to understand the frequency of 255 in 67646147.

Advancing to step 1:
6 divided by 255 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 255

Advancing to step 2:
When dividing 67 by 255, we get 0 with a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 67 leaves us with 67.
Fetch the next digit (6) from the dividend, attach it to 67 and continue: 676 / 255

Let's proceed to step 3:
255 goes into 676 2 times with a remainder of 166.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 510 from 676, we get 166.
Take the next digit (4) from the dividend and append it to 166, then repeat: 1664 / 255

Advancing to step 4:
When dividing 1664 by 255, we get 6 with a remainder of 134.
Put 6 as the next digit of the answer. 
Result so far: 26.0
If we take 1530 away from 1664, we end up with 134.
Bring next digit (6) of the dividend behind the 134 and repeat the process: 1346 / 255

Let's proceed to step 5:
255 goes into 1346 5 times with a remainder of 71.
Record the quotient 5 as the next digit in the result. 
Result so far: 265.0
If we subtract 1275 from 1346, we get 71.
Take the next digit (1) from the dividend and append it to 71, then repeat: 711 / 255

Advancing to step 6:
When dividing 711 by 255, we get 2 with a remainder of 201.
Record the quotient 2 as the next digit in the result. 
Result so far: 2652.0
Deduct 510 from 711 and we're left with 201.
Bring next digit (4) of the dividend behind the 201 and repeat the process: 2014 / 255

Advancing to step 7:
The number 255 fits into 2014 7 times, leaving a remainder of 229.
The next digit of our result is 7. 
Result so far: 26527.0
Deduct 1785 from 2014 and we're left with 229.
Grab the next digit (7) from the dividend, add it to 229, then carry on: 2297 / 255

Advancing to step 8:
255 goes into 2297 9 times with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 265279.0
If we take 2295 away from 2297, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
20 divided by 255 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 265279.0
If we subtract 0 from 20, 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.

Step 10:
255 can be fit into 200 0 times, resulting in a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 265279.0
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 265279.0 and a remainder of 0.2.
