97538155 ÷ 255 
The aim is to understand the frequency of 255 in 97538155.

Let's proceed to step 1:
When dividing 9 by 255, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 255

Going ahead to step 2:
97 divided by 255 is 0 with a remainder of 97.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 97 after subtracting 0 from 97.
Take the next digit (5) from the dividend and append it to 97, then repeat: 975 / 255

Advancing to step 3:
If we divide 975 by 255, we get 3 and a remainder of 210.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 765 from 975 leaves us with 210.
Include the next digit (3) from the dividend after 210, then repeat: 2103 / 255

On to step 4:
If we divide 2103 by 255, we get 8 and a remainder of 63.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Deduct 2040 from 2103 and we're left with 63.
Append the next digit (8) from the dividend to 63 and continue with: 638 / 255

On to step 5:
255 goes into 638 2 times with a remainder of 128.
The next digit of our result is 2. 
Result so far: 382.0
Subtract 510 from 638 to get 128.
Grab the next digit (1) from the dividend, add it to 128, then carry on: 1281 / 255

Advancing to step 6:
If we divide 1281 by 255, we get 5 and a remainder of 6.
The next digit of our result is 5. 
Result so far: 3825.0
If we take 1275 away from 1281, we end up with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 255

Advancing to step 7:
255 goes into 65 0 times with a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 38250.0
If we take 0 away from 65, we end up with 65.
Fetch the next digit (5) from the dividend, attach it to 65 and continue: 655 / 255

On to step 8:
If we divide 655 by 255, we get 2 and a remainder of 145.
The number 2 becomes the next digit in our result. 
Result so far: 382502.0
Subtract 510 from 655 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Moving on to step 9:
When dividing 1450 by 255, we get 5 with a remainder of 175.
Record the quotient 5 as the next digit in the result. 
Result so far: 382502.5
Deduct 1275 from 1450 and we're left 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 10:
255 can be fit into 1750 6 times, resulting in a remainder of 220.
The next digit of our result is 6. 
Result so far: 382502.56
If we take 1530 away from 1750, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 11:
When dividing 2200 by 255, we get 8 with a remainder of 160.
The number 8 becomes the next digit in our result. 
Result so far: 382502.568
Deduct 2040 from 2200 and we're left 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.

Moving on to step 12:
255 goes into 1600 6 times with a remainder of 70.
Put 6 as the next digit of the answer. 
Result so far: 382502.5686
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.

Step 13:
When dividing 700 by 255, we get 2 with a remainder of 190.
Record the quotient 2 as the next digit in the result. 
Result so far: 382502.56862
Deduct 510 from 700 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 14:
255 goes into 1900 7 times with a remainder of 115.
Put 7 as the next digit of the answer. 
Result so far: 382502.568627
Subtract 1785 from 1900 to get 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 15:
If we divide 1150 by 255, we get 4 and a remainder of 130.
Use 4 as the next digit of our solution. 
Result so far: 382502.5686274
Subtract 1020 from 1150 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 16:
1300 divided by 255 is 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 382502.56862745
Deduct 1275 from 1300 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 382502.56862745 with a remaining 2.5e-08.
