We're dividing 574682 by 66 
The aim is to understand the frequency of 66 in 574682.

Going ahead to step 1:
66 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 66

Step 2:
The number 66 fits into 57 0 times, leaving a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Take the next digit (4) from the dividend and append it to 57, then repeat: 574 / 66

On to step 3:
The number 66 fits into 574 8 times, leaving a remainder of 46.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 528 from 574 to get 46.
Include the next digit (6) from the dividend after 46, then repeat: 466 / 66

Step 4:
66 can be fit into 466 7 times, resulting in a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
If we subtract 462 from 466, we get 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 66

Let's proceed to step 5:
48 divided by 66 is 0 with a remainder of 48.
Use 0 as the next digit of our solution. 
Result so far: 870.0
The remainder is 48 after subtracting 0 from 48.
Include the next digit (2) from the dividend after 48, then repeat: 482 / 66

Advancing to step 6:
66 goes into 482 7 times with a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 8707.0
The remainder is 20 after subtracting 462 from 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 7:
If we divide 200 by 66, we get 3 and a remainder of 2.
The next digit of our result is 3. 
Result so far: 8707.3
If we subtract 198 from 200, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
66 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 8707.3
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
200 divided by 66 is 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 8707.303
If we take 198 away from 200, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
20 divided by 66 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 8707.303
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
200 divided by 66 is 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 8707.30303
The remainder is 2 after subtracting 198 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 12:
66 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 8707.30303
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
66 can be fit into 200 3 times, resulting in a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 8707.3030303
Deduct 198 from 200 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 14:
66 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 8707.3030303
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 8707.3030303 and a remainder of 2e-08.
