77760056 divided by 255 
The aim is to understand the frequency of 255 in 77760056.

Step 1:
When dividing 7 by 255, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 255

Going ahead to step 2:
The number 255 fits into 77 0 times, leaving a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Bring next digit (7) of the dividend behind the 77 and repeat the process: 777 / 255

On to step 3:
When dividing 777 by 255, we get 3 with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 765 away from 777, we end up with 12.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 255

Going ahead to step 4:
The number 255 fits into 126 0 times, leaving a remainder of 126.
The next digit of our result is 0. 
Result so far: 30.0
Subtract 0 from 126 to get 126.
Grab the next digit (0) from the dividend, add it to 126, then carry on: 1260 / 255

Advancing to step 5:
255 goes into 1260 4 times with a remainder of 240.
The next digit of our result is 4. 
Result so far: 304.0
Subtracting 1020 from 1260 leaves us with 240.
Append the next digit (0) from the dividend to 240 and continue with: 2400 / 255

Going ahead to step 6:
The number 255 fits into 2400 9 times, leaving a remainder of 105.
The number 9 becomes the next digit in our result. 
Result so far: 3049.0
Subtracting 2295 from 2400 leaves us with 105.
Take the next digit (5) from the dividend and append it to 105, then repeat: 1055 / 255

On to step 7:
255 goes into 1055 4 times with a remainder of 35.
Record the quotient 4 as the next digit in the result. 
Result so far: 30494.0
The remainder is 35 after subtracting 1020 from 1055.
Include the next digit (6) from the dividend after 35, then repeat: 356 / 255

Going ahead to step 8:
The number 255 fits into 356 1 times, leaving a remainder of 101.
Use 1 as the next digit of our solution. 
Result so far: 304941.0
Subtracting 255 from 356 leaves us with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

On to step 9:
255 can be fit into 1010 3 times, resulting in a remainder of 245.
Write down 3 as next digit of the result. 
Result so far: 304941.3
Deduct 765 from 1010 and we're left 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.

On to step 10:
When dividing 2450 by 255, we get 9 with a remainder of 155.
Use 9 as the next digit of our solution. 
Result so far: 304941.39
Deduct 2295 from 2450 and we're left 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.

Step 11:
When dividing 1550 by 255, we get 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 304941.396
If we take 1530 away from 1550, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
255 can be fit into 200 0 times, resulting in a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 304941.396
Subtracting 0 from 200 leaves us 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.

Going ahead to step 13:
The number 255 fits into 2000 7 times, leaving a remainder of 215.
Use 7 as the next digit of our solution. 
Result so far: 304941.39607
If we subtract 1785 from 2000, we get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Let's proceed to step 14:
2150 divided by 255 is 8 with a remainder of 110.
Record the quotient 8 as the next digit in the result. 
Result so far: 304941.396078
If we subtract 2040 from 2150, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 15:
255 can be fit into 1100 4 times, resulting in a remainder of 80.
Record the quotient 4 as the next digit in the result. 
Result so far: 304941.3960784
The remainder is 80 after subtracting 1020 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 16:
If we divide 800 by 255, we get 3 and a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 304941.39607843
The remainder is 35 after subtracting 765 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

In conclusion, the division gives 304941.39607843 with a balance of 3.5e-08.
