49783010 ÷ 255 
The aim is to understand the frequency of 255 in 49783010.

On to step 1:
If we divide 4 by 255, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 255

Advancing to step 2:
49 divided by 255 is 0 with a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 49 to get 49.
Append the next digit (7) from the dividend to 49 and continue with: 497 / 255

Moving on to step 3:
497 divided by 255 is 1 with a remainder of 242.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 255 from 497, we get 242.
Append the next digit (8) from the dividend to 242 and continue with: 2428 / 255

On to step 4:
When dividing 2428 by 255, we get 9 with a remainder of 133.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we take 2295 away from 2428, we end up with 133.
Include the next digit (3) from the dividend after 133, then repeat: 1333 / 255

Going ahead to step 5:
255 goes into 1333 5 times with a remainder of 58.
Use 5 as the next digit of our solution. 
Result so far: 195.0
The remainder is 58 after subtracting 1275 from 1333.
Grab the next digit (0) from the dividend, add it to 58, then carry on: 580 / 255

Going ahead to step 6:
255 goes into 580 2 times with a remainder of 70.
Put 2 as the next digit of the answer. 
Result so far: 1952.0
Subtracting 510 from 580 leaves us with 70.
Fetch the next digit (1) from the dividend, attach it to 70 and continue: 701 / 255

On to step 7:
When dividing 701 by 255, we get 2 with a remainder of 191.
The number 2 becomes the next digit in our result. 
Result so far: 19522.0
Subtracting 510 from 701 leaves us with 191.
Take the next digit (0) from the dividend and append it to 191, then repeat: 1910 / 255

Going ahead to step 8:
When dividing 1910 by 255, we get 7 with a remainder of 125.
Write down 7 as next digit of the result. 
Result so far: 195227.0
Subtract 1785 from 1910 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 9:
The number 255 fits into 1250 4 times, leaving a remainder of 230.
Record the quotient 4 as the next digit in the result. 
Result so far: 195227.4
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.

Advancing to step 10:
2300 divided by 255 is 9 with a remainder of 5.
The next digit of our result is 9. 
Result so far: 195227.49
The remainder is 5 after subtracting 2295 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 11:
255 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 195227.49
If we take 0 away from 50, we end up 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.

Let's proceed to step 12:
The number 255 fits into 500 1 times, leaving a remainder of 245.
The number 1 becomes the next digit in our result. 
Result so far: 195227.4901
If we subtract 255 from 500, we get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Advancing to step 13:
If we divide 2450 by 255, we get 9 and a remainder of 155.
Use 9 as the next digit of our solution. 
Result so far: 195227.49019
Subtract 2295 from 2450 to get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

On to step 14:
255 can be fit into 1550 6 times, resulting in a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 195227.490196
If we subtract 1530 from 1550, 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.

Moving on to step 15:
The number 255 fits into 200 0 times, leaving a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 195227.490196
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.

Step 16:
When dividing 2000 by 255, we get 7 with a remainder of 215.
The number 7 becomes the next digit in our result. 
Result so far: 195227.49019607
If we take 1785 away from 2000, we end up with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

The final result is 195227.49019607 with a remainder of 2.15e-07.
