We're dividing 175566 by 66 
The aim is to understand the frequency of 66 in 175566.

Let's proceed to step 1:
The number 66 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 66

Moving on to step 2:
The number 66 fits into 17 0 times, leaving a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Grab the next digit (5) from the dividend, add it to 17, then carry on: 175 / 66

Let's proceed to step 3:
66 can be fit into 175 2 times, resulting in a remainder of 43.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 132 from 175 to get 43.
Include the next digit (5) from the dividend after 43, then repeat: 435 / 66

Moving on to step 4:
66 can be fit into 435 6 times, resulting in a remainder of 39.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
If we subtract 396 from 435, we get 39.
Append the next digit (6) from the dividend to 39 and continue with: 396 / 66

Advancing to step 5:
396 divided by 66 is 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 266.0
If we subtract 396 from 396, we get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 66

Going ahead to step 6:
When dividing 6 by 66, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 2660.0
If we subtract 0 from 6, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
If we divide 60 by 66, we get 0 and a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 2660.0
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
If we divide 600 by 66, we get 9 and a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 2660.09
If we take 594 away from 600, we end up 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.

Moving on to step 9:
66 goes into 60 0 times with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 2660.09
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
66 goes into 600 9 times with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 2660.0909
The remainder is 6 after subtracting 594 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 11:
When dividing 60 by 66, we get 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 2660.0909
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 12:
600 divided by 66 is 9 with a remainder of 6.
The next digit of our result is 9. 
Result so far: 2660.090909
If we subtract 594 from 600, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
66 goes into 60 0 times with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 2660.090909
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 14:
When dividing 600 by 66, we get 9 with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 2660.09090909
If we subtract 594 from 600, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 2660.09090909, and the remainder is 6e-09.
