We look at the division of 165407 by 55 
The aim is to understand the frequency of 55 in 165407.

Step 1:
The number 55 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 55

Advancing to step 2:
If we divide 16 by 55, we get 0 and a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Include the next digit (5) from the dividend after 16, then repeat: 165 / 55

Let's proceed to step 3:
If we divide 165 by 55, we get 3 and a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 165 from 165 to get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 55

Going ahead to step 4:
55 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 30.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 55

Going ahead to step 5:
The number 55 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 300.0
Subtract 0 from 40 to get 40.
Grab the next digit (7) from the dividend, add it to 40, then carry on: 407 / 55

Let's proceed to step 6:
407 divided by 55 is 7 with a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 3007.0
Deduct 385 from 407 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
55 can be fit into 220 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 3007.4
Subtract 220 from 220 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
The number 55 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3007.4
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
If we divide 0 by 55, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3007.4
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 3007.4 with a remaining 0.0.
