We look at the division of 55180 by 55 
The aim is to understand the frequency of 55 in 55180.

Going ahead to step 1:
The number 55 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 55

Advancing to step 2:
The number 55 fits into 55 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 55 from 55 and we're left with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 55

Step 3:
The number 55 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 55

Let's proceed to step 4:
When dividing 18 by 55, we get 0 with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 100.0
Deduct 0 from 18 and we're left with 18.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 55

Moving on to step 5:
If we divide 180 by 55, we get 3 and a remainder of 15.
The next digit of our result is 3. 
Result so far: 1003.0
Subtract 165 from 180 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 6:
150 divided by 55 is 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 1003.2
Subtract 110 from 150 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 7:
The number 55 fits into 400 7 times, leaving a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 1003.27
The remainder is 15 after subtracting 385 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 8:
If we divide 150 by 55, we get 2 and a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 1003.272
Subtract 110 from 150 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
When dividing 400 by 55, we get 7 with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 1003.2727
Subtracting 385 from 400 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 10:
The number 55 fits into 150 2 times, leaving a remainder of 40.
The next digit of our result is 2. 
Result so far: 1003.27272
If we subtract 110 from 150, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
55 can be fit into 400 7 times, resulting in a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 1003.272727
If we take 385 away from 400, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 12:
150 divided by 55 is 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 1003.2727272
If we take 110 away from 150, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
When dividing 400 by 55, we get 7 with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 1003.27272727
The remainder is 15 after subtracting 385 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 1003.27272727 with a remaining 1.5e-08.
