89181913 ÷ 255 
The aim is to understand the frequency of 255 in 89181913.

Going ahead to step 1:
255 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 255

Going ahead to step 2:
If we divide 89 by 255, we get 0 and a remainder of 89.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 89, we end up with 89.
Include the next digit (1) from the dividend after 89, then repeat: 891 / 255

Going ahead to step 3:
255 can be fit into 891 3 times, resulting in a remainder of 126.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 765 from 891 and we're left with 126.
Grab the next digit (8) from the dividend, add it to 126, then carry on: 1268 / 255

Step 4:
255 can be fit into 1268 4 times, resulting in a remainder of 248.
Put 4 as the next digit of the answer. 
Result so far: 34.0
Deduct 1020 from 1268 and we're left with 248.
Append the next digit (1) from the dividend to 248 and continue with: 2481 / 255

Step 5:
If we divide 2481 by 255, we get 9 and a remainder of 186.
Put 9 as the next digit of the answer. 
Result so far: 349.0
Subtracting 2295 from 2481 leaves us with 186.
Grab the next digit (9) from the dividend, add it to 186, then carry on: 1869 / 255

Step 6:
1869 divided by 255 is 7 with a remainder of 84.
Use 7 as the next digit of our solution. 
Result so far: 3497.0
Subtracting 1785 from 1869 leaves us with 84.
Grab the next digit (1) from the dividend, add it to 84, then carry on: 841 / 255

Moving on to step 7:
255 goes into 841 3 times with a remainder of 76.
Write down 3 as next digit of the result. 
Result so far: 34973.0
If we take 765 away from 841, we end up with 76.
Bring next digit (3) of the dividend behind the 76 and repeat the process: 763 / 255

Let's proceed to step 8:
255 can be fit into 763 2 times, resulting in a remainder of 253.
Record the quotient 2 as the next digit in the result. 
Result so far: 349732.0
Subtract 510 from 763 to get 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Step 9:
If we divide 2530 by 255, we get 9 and a remainder of 235.
Record the quotient 9 as the next digit in the result. 
Result so far: 349732.9
Subtract 2295 from 2530 to get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Let's proceed to step 10:
255 goes into 2350 9 times with a remainder of 55.
Put 9 as the next digit of the answer. 
Result so far: 349732.99
Subtract 2295 from 2350 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The quotient of the division is 349732.99, and the remainder is 0.055.
