We're dividing 70504866 by 255 
The aim is to understand the frequency of 255 in 70504866.

On to step 1:
255 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 255

On to step 2:
The number 255 fits into 70 0 times, leaving a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Fetch the next digit (5) from the dividend, attach it to 70 and continue: 705 / 255

Advancing to step 3:
255 can be fit into 705 2 times, resulting in a remainder of 195.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 510 away from 705, we end up with 195.
Bring next digit (0) of the dividend behind the 195 and repeat the process: 1950 / 255

Step 4:
The number 255 fits into 1950 7 times, leaving a remainder of 165.
Use 7 as the next digit of our solution. 
Result so far: 27.0
If we take 1785 away from 1950, we end up with 165.
Bring next digit (4) of the dividend behind the 165 and repeat the process: 1654 / 255

Advancing to step 5:
The number 255 fits into 1654 6 times, leaving a remainder of 124.
Use 6 as the next digit of our solution. 
Result so far: 276.0
Subtracting 1530 from 1654 leaves us with 124.
Take the next digit (8) from the dividend and append it to 124, then repeat: 1248 / 255

Moving on to step 6:
255 goes into 1248 4 times with a remainder of 228.
Write down 4 as next digit of the result. 
Result so far: 2764.0
If we take 1020 away from 1248, we end up with 228.
Bring next digit (6) of the dividend behind the 228 and repeat the process: 2286 / 255

Step 7:
When dividing 2286 by 255, we get 8 with a remainder of 246.
Record the quotient 8 as the next digit in the result. 
Result so far: 27648.0
Subtracting 2040 from 2286 leaves us with 246.
Bring next digit (6) of the dividend behind the 246 and repeat the process: 2466 / 255

Let's proceed to step 8:
The number 255 fits into 2466 9 times, leaving a remainder of 171.
Write down 9 as next digit of the result. 
Result so far: 276489.0
If we take 2295 away from 2466, we end up with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Going ahead to step 9:
1710 divided by 255 is 6 with a remainder of 180.
The next digit of our result is 6. 
Result so far: 276489.6
Subtract 1530 from 1710 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 10:
When dividing 1800 by 255, we get 7 with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 276489.67
The remainder is 15 after subtracting 1785 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
When dividing 150 by 255, we get 0 with a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 276489.67
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 12:
When dividing 1500 by 255, we get 5 with a remainder of 225.
Write down 5 as next digit of the result. 
Result so far: 276489.6705
Subtracting 1275 from 1500 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Going ahead to step 13:
255 can be fit into 2250 8 times, resulting in a remainder of 210.
The number 8 becomes the next digit in our result. 
Result so far: 276489.67058
If we subtract 2040 from 2250, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 14:
If we divide 2100 by 255, we get 8 and a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 276489.670588
Subtracting 2040 from 2100 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 276489.670588 with a remainder of 6e-06.
