We're dividing 495548 by 66 
The aim is to understand the frequency of 66 in 495548.

Moving on to step 1:
4 divided by 66 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 66

Let's proceed to step 2:
When dividing 49 by 66, we get 0 with a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 49, we end up with 49.
Take the next digit (5) from the dividend and append it to 49, then repeat: 495 / 66

On to step 3:
66 can be fit into 495 7 times, resulting in a remainder of 33.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 33 after subtracting 462 from 495.
Append the next digit (5) from the dividend to 33 and continue with: 335 / 66

On to step 4:
66 can be fit into 335 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 75.0
Subtract 330 from 335 to get 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 66

Advancing to step 5:
66 can be fit into 54 0 times, resulting in a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 750.0
Deduct 0 from 54 and we're left with 54.
Bring next digit (8) of the dividend behind the 54 and repeat the process: 548 / 66

Going ahead to step 6:
66 can be fit into 548 8 times, resulting in a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 7508.0
Subtracting 528 from 548 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
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: 7508.3
Subtracting 198 from 200 leaves us 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.

Advancing to step 8:
20 divided by 66 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 7508.3
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.

On to step 9:
When dividing 200 by 66, we get 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 7508.303
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.

Advancing to step 10:
If we divide 20 by 66, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 7508.303
Deduct 0 from 20 and we're left with 20.
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 11:
66 goes into 200 3 times with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 7508.30303
Subtracting 198 from 200 leaves us 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 12:
20 divided by 66 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 7508.30303
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 13:
200 divided by 66 is 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 7508.3030303
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.

Let's proceed to step 14:
20 divided by 66 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 7508.3030303
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.

Our division results in 7508.3030303 with a remaining 2e-08.
