We look at the division of 90689536 by 455 
The aim is to understand the frequency of 455 in 90689536.

Let's proceed to step 1:
If we divide 9 by 455, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 455

Going ahead to step 2:
90 divided by 455 is 0 with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Grab the next digit (6) from the dividend, add it to 90, then carry on: 906 / 455

Moving on to step 3:
455 can be fit into 906 1 times, resulting in a remainder of 451.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 455 from 906, we get 451.
Take the next digit (8) from the dividend and append it to 451, then repeat: 4518 / 455

On to step 4:
If we divide 4518 by 455, we get 9 and a remainder of 423.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we subtract 4095 from 4518, we get 423.
Append the next digit (9) from the dividend to 423 and continue with: 4239 / 455

On to step 5:
455 goes into 4239 9 times with a remainder of 144.
Record the quotient 9 as the next digit in the result. 
Result so far: 199.0
Subtracting 4095 from 4239 leaves us with 144.
Bring next digit (5) of the dividend behind the 144 and repeat the process: 1445 / 455

Advancing to step 6:
The number 455 fits into 1445 3 times, leaving a remainder of 80.
The next digit of our result is 3. 
Result so far: 1993.0
Subtract 1365 from 1445 to get 80.
Grab the next digit (3) from the dividend, add it to 80, then carry on: 803 / 455

Moving on to step 7:
803 divided by 455 is 1 with a remainder of 348.
The number 1 becomes the next digit in our result. 
Result so far: 19931.0
If we subtract 455 from 803, we get 348.
Grab the next digit (6) from the dividend, add it to 348, then carry on: 3486 / 455

Going ahead to step 8:
3486 divided by 455 is 7 with a remainder of 301.
Put 7 as the next digit of the answer. 
Result so far: 199317.0
The remainder is 301 after subtracting 3185 from 3486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Moving on to step 9:
If we divide 3010 by 455, we get 6 and a remainder of 280.
Put 6 as the next digit of the answer. 
Result so far: 199317.6
Subtract 2730 from 3010 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 10:
2800 divided by 455 is 6 with a remainder of 70.
Record the quotient 6 as the next digit in the result. 
Result so far: 199317.66
Subtract 2730 from 2800 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 199317.66 with a remaining 0.07.
