We look at the division of 661146 by 55 
The aim is to understand the frequency of 55 in 661146.

Step 1:
6 divided by 55 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 55

Going ahead to step 2:
66 divided by 55 is 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 55 from 66 to get 11.
Append the next digit (1) from the dividend to 11 and continue with: 111 / 55

Moving on to step 3:
55 goes into 111 2 times with a remainder of 1.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 110 from 111 to get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 55

Moving on to step 4:
If we divide 11 by 55, we get 0 and a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 120.0
If we take 0 away from 11, we end up with 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 55

Let's proceed to step 5:
When dividing 114 by 55, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 1202.0
If we take 110 away from 114, we end up with 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 55

Let's proceed to step 6:
46 divided by 55 is 0 with a remainder of 46.
The next digit of our result is 0. 
Result so far: 12020.0
If we subtract 0 from 46, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 7:
If we divide 460 by 55, we get 8 and a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 12020.8
If we subtract 440 from 460, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
200 divided by 55 is 3 with a remainder of 35.
Write down 3 as next digit of the result. 
Result so far: 12020.83
Deduct 165 from 200 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 9:
55 can be fit into 350 6 times, resulting in a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 12020.836
Subtracting 330 from 350 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
55 goes into 200 3 times with a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 12020.8363
The remainder is 35 after subtracting 165 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 11:
350 divided by 55 is 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 12020.83636
The remainder is 20 after subtracting 330 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
If we divide 200 by 55, we get 3 and a remainder of 35.
The next digit of our result is 3. 
Result so far: 12020.836363
Subtracting 165 from 200 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 13:
55 goes into 350 6 times with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 12020.8363636
If we take 330 away from 350, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
The number 55 fits into 200 3 times, leaving a remainder of 35.
Put 3 as the next digit of the answer. 
Result so far: 12020.83636363
Deduct 165 from 200 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The quotient of the division is 12020.83636363, and the remainder is 3.5e-08.
