We're dividing 70961369 by 255 
The aim is to understand the frequency of 255 in 70961369.

Going ahead to step 1:
The number 255 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 255

Step 2:
255 goes into 70 0 times with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Grab the next digit (9) from the dividend, add it to 70, then carry on: 709 / 255

Advancing to step 3:
255 goes into 709 2 times with a remainder of 199.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 510 from 709 leaves us with 199.
Grab the next digit (6) from the dividend, add it to 199, then carry on: 1996 / 255

On to step 4:
255 can be fit into 1996 7 times, resulting in a remainder of 211.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Deduct 1785 from 1996 and we're left with 211.
Take the next digit (1) from the dividend and append it to 211, then repeat: 2111 / 255

Advancing to step 5:
255 goes into 2111 8 times with a remainder of 71.
The number 8 becomes the next digit in our result. 
Result so far: 278.0
The remainder is 71 after subtracting 2040 from 2111.
Bring next digit (3) of the dividend behind the 71 and repeat the process: 713 / 255

Advancing to step 6:
255 goes into 713 2 times with a remainder of 203.
The number 2 becomes the next digit in our result. 
Result so far: 2782.0
Subtract 510 from 713 to get 203.
Include the next digit (6) from the dividend after 203, then repeat: 2036 / 255

Let's proceed to step 7:
255 can be fit into 2036 7 times, resulting in a remainder of 251.
Put 7 as the next digit of the answer. 
Result so far: 27827.0
If we subtract 1785 from 2036, we get 251.
Grab the next digit (9) from the dividend, add it to 251, then carry on: 2519 / 255

Going ahead to step 8:
255 goes into 2519 9 times with a remainder of 224.
Put 9 as the next digit of the answer. 
Result so far: 278279.0
If we subtract 2295 from 2519, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Let's proceed to step 9:
The number 255 fits into 2240 8 times, leaving a remainder of 200.
Put 8 as the next digit of the answer. 
Result so far: 278279.8
If we take 2040 away from 2240, 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.

Advancing to step 10:
2000 divided by 255 is 7 with a remainder of 215.
Record the quotient 7 as the next digit in the result. 
Result so far: 278279.87
The remainder is 215 after subtracting 1785 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Step 11:
The number 255 fits into 2150 8 times, leaving a remainder of 110.
The next digit of our result is 8. 
Result so far: 278279.878
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.

Step 12:
1100 divided by 255 is 4 with a remainder of 80.
Record the quotient 4 as the next digit in the result. 
Result so far: 278279.8784
Subtracting 1020 from 1100 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
255 can be fit into 800 3 times, resulting in a remainder of 35.
Record the quotient 3 as the next digit in the result. 
Result so far: 278279.87843
Subtract 765 from 800 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 14:
If we divide 350 by 255, we get 1 and a remainder of 95.
Use 1 as the next digit of our solution. 
Result so far: 278279.878431
If we subtract 255 from 350, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 15:
When dividing 950 by 255, we get 3 with a remainder of 185.
The next digit of our result is 3. 
Result so far: 278279.8784313
Subtract 765 from 950 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Going ahead to step 16:
The number 255 fits into 1850 7 times, leaving a remainder of 65.
Use 7 as the next digit of our solution. 
Result so far: 278279.87843137
If we take 1785 away from 1850, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Our division results in 278279.87843137 with a remaining 6.5e-08.
