972620 ÷ 66 
The aim is to understand the frequency of 66 in 972620.

Going ahead to step 1:
When dividing 9 by 66, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 66

Advancing to step 2:
If we divide 97 by 66, we get 1 and a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 66 from 97, we get 31.
Fetch the next digit (2) from the dividend, attach it to 31 and continue: 312 / 66

Step 3:
66 can be fit into 312 4 times, resulting in a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we take 264 away from 312, we end up with 48.
Bring next digit (6) of the dividend behind the 48 and repeat the process: 486 / 66

On to step 4:
If we divide 486 by 66, we get 7 and a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 147.0
Subtracting 462 from 486 leaves us with 24.
Fetch the next digit (2) from the dividend, attach it to 24 and continue: 242 / 66

Let's proceed to step 5:
If we divide 242 by 66, we get 3 and a remainder of 44.
The number 3 becomes the next digit in our result. 
Result so far: 1473.0
The remainder is 44 after subtracting 198 from 242.
Append the next digit (0) from the dividend to 44 and continue with: 440 / 66

Advancing to step 6:
The number 66 fits into 440 6 times, leaving a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 14736.0
If we subtract 396 from 440, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 7:
66 can be fit into 440 6 times, resulting in a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 14736.6
If we subtract 396 from 440, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 8:
When dividing 440 by 66, we get 6 with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 14736.66
Subtracting 396 from 440 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

In conclusion, the division gives 14736.66 with a balance of 0.044.
