548511 ÷ 55 
The aim is to understand the frequency of 55 in 548511.

Going ahead to step 1:
5 divided by 55 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 55

Step 2:
54 divided by 55 is 0 with a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Append the next digit (8) from the dividend to 54 and continue with: 548 / 55

Going ahead to step 3:
548 divided by 55 is 9 with a remainder of 53.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 495 from 548 leaves us with 53.
Include the next digit (5) from the dividend after 53, then repeat: 535 / 55

Step 4:
55 can be fit into 535 9 times, resulting in a remainder of 40.
Put 9 as the next digit of the answer. 
Result so far: 99.0
Subtracting 495 from 535 leaves us with 40.
Append the next digit (1) from the dividend to 40 and continue with: 401 / 55

Step 5:
401 divided by 55 is 7 with a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 997.0
Subtract 385 from 401 to get 16.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 55

Moving on to step 6:
If we divide 161 by 55, we get 2 and a remainder of 51.
The number 2 becomes the next digit in our result. 
Result so far: 9972.0
If we take 110 away from 161, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 7:
The number 55 fits into 510 9 times, leaving a remainder of 15.
The next digit of our result is 9. 
Result so far: 9972.9
The remainder is 15 after subtracting 495 from 510.
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 8:
55 goes into 150 2 times with a remainder of 40.
The next digit of our result is 2. 
Result so far: 9972.92
Deduct 110 from 150 and we're left 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.

Let's proceed to step 9:
400 divided by 55 is 7 with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 9972.927
Subtract 385 from 400 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.

Advancing to step 10:
When dividing 150 by 55, we get 2 with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 9972.9272
Subtracting 110 from 150 leaves us 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.

Moving on 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: 9972.92727
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:
55 can be fit into 150 2 times, resulting in a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 9972.927272
Deduct 110 from 150 and we're left 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.

Moving on to step 13:
When dividing 400 by 55, we get 7 with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 9972.9272727
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.

Let's proceed to step 14:
When dividing 150 by 55, we get 2 with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 9972.92727272
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.

The final outcome is 9972.92727272, with a leftover of 4e-08.
