We look at the division of 553966 by 55 
The aim is to understand the frequency of 55 in 553966.

Advancing to step 1:
55 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 55

On to step 2:
If we divide 55 by 55, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 55 from 55 leaves us with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 55

Let's proceed to step 3:
The number 55 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 55

Going ahead to step 4:
If we divide 39 by 55, we get 0 and a remainder of 39.
The next digit of our result is 0. 
Result so far: 100.0
Deduct 0 from 39 and we're left with 39.
Include the next digit (6) from the dividend after 39, then repeat: 396 / 55

Moving on to step 5:
When dividing 396 by 55, we get 7 with a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 1007.0
If we take 385 away from 396, we end up with 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 55

Going ahead to step 6:
55 can be fit into 116 2 times, resulting in a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 10072.0
Deduct 110 from 116 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
If we divide 60 by 55, we get 1 and a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 10072.1
If we take 55 away from 60, 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.

Let's proceed to step 8:
55 goes into 50 0 times with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 10072.1
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.

Let's proceed to step 9:
When dividing 500 by 55, we get 9 with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 10072.109
The remainder is 5 after subtracting 495 from 500.
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 10:
55 goes into 50 0 times with a remainder of 50.
The next digit of our result is 0. 
Result so far: 10072.109
If we take 0 away from 50, we end up 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.

Step 11:
55 can be fit into 500 9 times, resulting in a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 10072.10909
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.

Step 12:
If we divide 50 by 55, we get 0 and a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 10072.10909
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.

On to step 13:
55 goes into 500 9 times with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 10072.1090909
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.

On to step 14:
55 can be fit into 50 0 times, resulting in a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 10072.1090909
Subtracting 0 from 50 leaves us 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.

The quotient of the division is 10072.1090909, and the remainder is 5e-08.
