47997 divided by 66 
The aim is to understand the frequency of 66 in 47997.

Step 1:
The number 66 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 66

Advancing to step 2:
47 divided by 66 is 0 with a remainder of 47.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 47, we end up with 47.
Bring next digit (9) of the dividend behind the 47 and repeat the process: 479 / 66

Moving on to step 3:
479 divided by 66 is 7 with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 17 after subtracting 462 from 479.
Bring next digit (9) of the dividend behind the 17 and repeat the process: 179 / 66

On to step 4:
179 divided by 66 is 2 with a remainder of 47.
The next digit of our result is 2. 
Result so far: 72.0
Deduct 132 from 179 and we're left with 47.
Include the next digit (7) from the dividend after 47, then repeat: 477 / 66

Let's proceed to step 5:
When dividing 477 by 66, we get 7 with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 727.0
The remainder is 15 after subtracting 462 from 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 6:
The number 66 fits into 150 2 times, leaving a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 727.2
Subtract 132 from 150 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
66 can be fit into 180 2 times, resulting in a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 727.22
Subtract 132 from 180 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final result is 727.22 with a remainder of 0.048.
