We're dividing 422847 by 66 
The aim is to understand the frequency of 66 in 422847.

Let's proceed to step 1:
66 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 66

Let's proceed to step 2:
When dividing 42 by 66, we get 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Include the next digit (2) from the dividend after 42, then repeat: 422 / 66

Step 3:
66 can be fit into 422 6 times, resulting in a remainder of 26.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 396 from 422 leaves us with 26.
Append the next digit (8) from the dividend to 26 and continue with: 268 / 66

Advancing to step 4:
If we divide 268 by 66, we get 4 and a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 64.0
The remainder is 4 after subtracting 264 from 268.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 66

Moving on to step 5:
44 divided by 66 is 0 with a remainder of 44.
Use 0 as the next digit of our solution. 
Result so far: 640.0
If we take 0 away from 44, we end up with 44.
Bring next digit (7) of the dividend behind the 44 and repeat the process: 447 / 66

Let's proceed to step 6:
447 divided by 66 is 6 with a remainder of 51.
Record the quotient 6 as the next digit in the result. 
Result so far: 6406.0
Deduct 396 from 447 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 7:
510 divided by 66 is 7 with a remainder of 48.
Write down 7 as next digit of the result. 
Result so far: 6406.7
Deduct 462 from 510 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 8:
When dividing 480 by 66, we get 7 with a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 6406.77
Deduct 462 from 480 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 6406.77 with a remainder of 0.018.
