We're dividing 303489 by 55 
The aim is to understand the frequency of 55 in 303489.

Going ahead to step 1:
3 divided by 55 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 55

Let's proceed to step 2:
30 divided by 55 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Append the next digit (3) from the dividend to 30 and continue with: 303 / 55

Advancing to step 3:
When dividing 303 by 55, we get 5 with a remainder of 28.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 275 from 303 leaves us with 28.
Append the next digit (4) from the dividend to 28 and continue with: 284 / 55

Moving on to step 4:
284 divided by 55 is 5 with a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
If we subtract 275 from 284, we get 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 55

Moving on to step 5:
If we divide 98 by 55, we get 1 and a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 551.0
Deduct 55 from 98 and we're left with 43.
Append the next digit (9) from the dividend to 43 and continue with: 439 / 55

Let's proceed to step 6:
55 can be fit into 439 7 times, resulting in a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 5517.0
If we subtract 385 from 439, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 7:
If we divide 540 by 55, we get 9 and a remainder of 45.
Use 9 as the next digit of our solution. 
Result so far: 5517.9
The remainder is 45 after subtracting 495 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 8:
The number 55 fits into 450 8 times, leaving a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 5517.98
If we subtract 440 from 450, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
When dividing 100 by 55, we get 1 with a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 5517.981
Subtract 55 from 100 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 10:
55 can be fit into 450 8 times, resulting in a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 5517.9818
The remainder is 10 after subtracting 440 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
When dividing 100 by 55, we get 1 with a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 5517.98181
Deduct 55 from 100 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 12:
55 can be fit into 450 8 times, resulting in a remainder of 10.
The next digit of our result is 8. 
Result so far: 5517.981818
If we subtract 440 from 450, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 13:
The number 55 fits into 100 1 times, leaving a remainder of 45.
The next digit of our result is 1. 
Result so far: 5517.9818181
If we subtract 55 from 100, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 14:
450 divided by 55 is 8 with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 5517.98181818
Subtracting 440 from 450 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 5517.98181818 with a remainder of 1e-08.
