We look at the division of 804480 by 55 
The aim is to understand the frequency of 55 in 804480.

Step 1:
55 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 55

Let's proceed to step 2:
If we divide 80 by 55, we get 1 and a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 55 away from 80, we end up with 25.
Bring next digit (4) of the dividend behind the 25 and repeat the process: 254 / 55

On to step 3:
254 divided by 55 is 4 with a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 220 from 254 leaves us with 34.
Fetch the next digit (4) from the dividend, attach it to 34 and continue: 344 / 55

Moving on to step 4:
The number 55 fits into 344 6 times, leaving a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 146.0
Deduct 330 from 344 and we're left with 14.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 55

On to step 5:
55 goes into 148 2 times with a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 1462.0
If we subtract 110 from 148, we get 38.
Include the next digit (0) from the dividend after 38, then repeat: 380 / 55

Step 6:
The number 55 fits into 380 6 times, leaving a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 14626.0
If we subtract 330 from 380, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 7:
55 can be fit into 500 9 times, resulting in a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 14626.9
If we subtract 495 from 500, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
50 divided by 55 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 14626.9
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
55 can be fit into 500 9 times, resulting in a remainder of 5.
The next digit of our result is 9. 
Result so far: 14626.909
If we take 495 away from 500, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
55 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 14626.909
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 11:
The number 55 fits into 500 9 times, leaving a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 14626.90909
Subtract 495 from 500 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 12:
The number 55 fits into 50 0 times, leaving a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 14626.90909
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 13:
55 can be fit into 500 9 times, resulting in a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 14626.9090909
Deduct 495 from 500 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 14:
When dividing 50 by 55, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 14626.9090909
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 14626.9090909 with a remainder of 5e-08.
