391204 divided by 55 
The aim is to understand the frequency of 55 in 391204.

Let's proceed to step 1:
If we divide 3 by 55, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 55

Step 2:
55 goes into 39 0 times with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Grab the next digit (1) from the dividend, add it to 39, then carry on: 391 / 55

Going ahead to step 3:
55 can be fit into 391 7 times, resulting in a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 385 from 391, we get 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 55

On to step 4:
The number 55 fits into 62 1 times, leaving a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
If we take 55 away from 62, we end up with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 55

Moving on to step 5:
70 divided by 55 is 1 with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 711.0
If we subtract 55 from 70, we get 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 55

Let's proceed to step 6:
The number 55 fits into 154 2 times, leaving a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 7112.0
The remainder is 44 after subtracting 110 from 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 7:
The number 55 fits into 440 8 times, leaving a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 7112.8
The remainder is 0 after subtracting 440 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
55 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 7112.8
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.

Step 9:
When dividing 0 by 55, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7112.8
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.

Our division results in 7112.8 with a remaining 0.0.
