We're dividing 561685 by 55 
The aim is to understand the frequency of 55 in 561685.

Let's proceed to step 1:
When dividing 5 by 55, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 55

Going ahead to step 2:
55 goes into 56 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 1 after subtracting 55 from 56.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 55

Moving on to step 3:
11 divided by 55 is 0 with a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 11 and we're left with 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 55

Advancing to step 4:
55 can be fit into 116 2 times, resulting in a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
Deduct 110 from 116 and we're left with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 55

Step 5:
The number 55 fits into 68 1 times, leaving a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1021.0
Deduct 55 from 68 and we're left with 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 55

Advancing to step 6:
When dividing 135 by 55, we get 2 with a remainder of 25.
Put 2 as the next digit of the answer. 
Result so far: 10212.0
If we subtract 110 from 135, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 7:
The number 55 fits into 250 4 times, leaving a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 10212.4
The remainder is 30 after subtracting 220 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
300 divided by 55 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 10212.45
Subtracting 275 from 300 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
The number 55 fits into 250 4 times, leaving a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 10212.454
Subtract 220 from 250 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
55 goes into 300 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 10212.4545
Subtracting 275 from 300 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 11:
The number 55 fits into 250 4 times, leaving a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 10212.45454
If we take 220 away from 250, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 12:
300 divided by 55 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 10212.454545
The remainder is 25 after subtracting 275 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 13:
When dividing 250 by 55, we get 4 with a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 10212.4545454
If we subtract 220 from 250, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 14:
When dividing 300 by 55, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 10212.45454545
Subtract 275 from 300 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 10212.45454545 with a remaining 2.5e-08.
