We're dividing 529269 by 66 
The aim is to understand the frequency of 66 in 529269.

Moving on to step 1:
When dividing 5 by 66, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 66

Step 2:
52 divided by 66 is 0 with a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Append the next digit (9) from the dividend to 52 and continue with: 529 / 66

Let's proceed to step 3:
66 can be fit into 529 8 times, resulting in a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 1 after subtracting 528 from 529.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 66

Advancing to step 4:
The number 66 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 80.0
Subtracting 0 from 12 leaves us with 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 66

Step 5:
66 goes into 126 1 times with a remainder of 60.
Write down 1 as next digit of the result. 
Result so far: 801.0
Subtract 66 from 126 to get 60.
Take the next digit (9) from the dividend and append it to 60, then repeat: 609 / 66

Advancing to step 6:
609 divided by 66 is 9 with a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 8019.0
If we take 594 away from 609, 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 7:
66 goes into 150 2 times with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 8019.2
The remainder is 18 after subtracting 132 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 8:
If we divide 180 by 66, we get 2 and a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 8019.22
The remainder is 48 after subtracting 132 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 8019.22 and a remainder of 0.048.
