We look at the division of 993243 by 55 
The aim is to understand the frequency of 55 in 993243.

On to step 1:
When dividing 9 by 55, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 55

Moving on to step 2:
55 goes into 99 1 times with a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 44 after subtracting 55 from 99.
Append the next digit (3) from the dividend to 44 and continue with: 443 / 55

On to step 3:
When dividing 443 by 55, we get 8 with a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtract 440 from 443 to get 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 55

Step 4:
55 can be fit into 32 0 times, resulting in a remainder of 32.
The number 0 becomes the next digit in our result. 
Result so far: 180.0
Subtract 0 from 32 to get 32.
Include the next digit (4) from the dividend after 32, then repeat: 324 / 55

Step 5:
55 can be fit into 324 5 times, resulting in a remainder of 49.
The number 5 becomes the next digit in our result. 
Result so far: 1805.0
If we subtract 275 from 324, we get 49.
Include the next digit (3) from the dividend after 49, then repeat: 493 / 55

Advancing to step 6:
The number 55 fits into 493 8 times, leaving a remainder of 53.
Write down 8 as next digit of the result. 
Result so far: 18058.0
If we take 440 away from 493, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 7:
55 goes into 530 9 times with a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 18058.9
The remainder is 35 after subtracting 495 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 8:
If we divide 350 by 55, we get 6 and a remainder of 20.
The next digit of our result is 6. 
Result so far: 18058.96
If we subtract 330 from 350, 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 9:
If we divide 200 by 55, we get 3 and a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 18058.963
Deduct 165 from 200 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 10:
55 goes into 350 6 times with a remainder of 20.
The next digit of our result is 6. 
Result so far: 18058.9636
If we subtract 330 from 350, 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 11:
55 can be fit into 200 3 times, resulting in a remainder of 35.
The next digit of our result is 3. 
Result so far: 18058.96363
Subtract 165 from 200 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.

Going ahead to step 12:
350 divided by 55 is 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 18058.963636
If we take 330 away from 350, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
55 can be fit into 200 3 times, resulting in a remainder of 35.
Write down 3 as next digit of the result. 
Result so far: 18058.9636363
Subtracting 165 from 200 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 14:
The number 55 fits into 350 6 times, leaving a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 18058.96363636
If we take 330 away from 350, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 18058.96363636 and a remainder of 2e-08.
