We're dividing 328456 by 66 
The aim is to understand the frequency of 66 in 328456.

Advancing to step 1:
If we divide 3 by 66, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 66

Moving on to step 2:
The number 66 fits into 32 0 times, leaving a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 32 leaves us with 32.
Append the next digit (8) from the dividend to 32 and continue with: 328 / 66

Let's proceed to step 3:
If we divide 328 by 66, we get 4 and a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 264 from 328 to get 64.
Include the next digit (4) from the dividend after 64, then repeat: 644 / 66

Going ahead to step 4:
644 divided by 66 is 9 with a remainder of 50.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
If we subtract 594 from 644, we get 50.
Fetch the next digit (5) from the dividend, attach it to 50 and continue: 505 / 66

Moving on to step 5:
When dividing 505 by 66, we get 7 with a remainder of 43.
The next digit of our result is 7. 
Result so far: 497.0
If we take 462 away from 505, we end up with 43.
Fetch the next digit (6) from the dividend, attach it to 43 and continue: 436 / 66

Advancing to step 6:
The number 66 fits into 436 6 times, leaving a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 4976.0
Deduct 396 from 436 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 7:
If we divide 400 by 66, we get 6 and a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 4976.6
The remainder is 4 after subtracting 396 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
66 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 4976.6
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
If we divide 400 by 66, we get 6 and a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 4976.606
Subtracting 396 from 400 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
The number 66 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 4976.606
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
66 goes into 400 6 times with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 4976.60606
If we take 396 away from 400, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 12:
The number 66 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 4976.60606
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 13:
The number 66 fits into 400 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 4976.6060606
Subtracting 396 from 400 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
66 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 4976.6060606
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 4976.6060606 with a remainder of 4e-08.
