We divide 38966690 by 255
The aim is to understand the frequency of 255 in 38966690.

Let's proceed to step 1:
The number 255 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 255

Let's proceed to step 2:
255 can be fit into 38 0 times, resulting in a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Grab the next digit (9) from the dividend, add it to 38, then carry on: 389 / 255

Going ahead to step 3:
The number 255 fits into 389 1 times, leaving a remainder of 134.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 255 from 389 to get 134.
Include the next digit (6) from the dividend after 134, then repeat: 1346 / 255

Advancing to step 4:
When dividing 1346 by 255, we get 5 with a remainder of 71.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 1275 from 1346, we get 71.
Append the next digit (6) from the dividend to 71 and continue with: 716 / 255

Step 5:
If we divide 716 by 255, we get 2 and a remainder of 206.
Write down 2 as next digit of the result. 
Result so far: 152.0
The remainder is 206 after subtracting 510 from 716.
Include the next digit (6) from the dividend after 206, then repeat: 2066 / 255

Going ahead to step 6:
255 can be fit into 2066 8 times, resulting in a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 1528.0
The remainder is 26 after subtracting 2040 from 2066.
Fetch the next digit (9) from the dividend, attach it to 26 and continue: 269 / 255

Step 7:
When dividing 269 by 255, we get 1 with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 15281.0
If we subtract 255 from 269, we get 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 255

On to step 8:
255 goes into 140 0 times with a remainder of 140.
The number 0 becomes the next digit in our result. 
Result so far: 152810.0
If we subtract 0 from 140, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 9:
If we divide 1400 by 255, we get 5 and a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 152810.5
If we take 1275 away from 1400, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 10:
255 goes into 1250 4 times with a remainder of 230.
The next digit of our result is 4. 
Result so far: 152810.54
Subtract 1020 from 1250 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 11:
When dividing 2300 by 255, we get 9 with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 152810.549
Subtracting 2295 from 2300 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 12:
When dividing 50 by 255, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 152810.549
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 13:
The number 255 fits into 500 1 times, leaving a remainder of 245.
Put 1 as the next digit of the answer. 
Result so far: 152810.54901
If we take 255 away from 500, we end up with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Going ahead to step 14:
The number 255 fits into 2450 9 times, leaving a remainder of 155.
Put 9 as the next digit of the answer. 
Result so far: 152810.549019
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.

Moving on to step 15:
When dividing 1550 by 255, we get 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 152810.5490196
Subtract 1530 from 1550 to 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.

Going ahead to step 16:
255 goes into 200 0 times with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 152810.5490196
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.

The final outcome is 152810.5490196, with a leftover of 2e-07.
