Let's divide 970574 by 66
The aim is to understand the frequency of 66 in 970574.

Moving on to step 1:
If we divide 9 by 66, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 66

Moving on to step 2:
If we divide 97 by 66, we get 1 and a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 66 from 97 leaves us with 31.
Bring next digit (0) of the dividend behind the 31 and repeat the process: 310 / 66

Going ahead to step 3:
66 goes into 310 4 times with a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 46 after subtracting 264 from 310.
Grab the next digit (5) from the dividend, add it to 46, then carry on: 465 / 66

Advancing to step 4:
When dividing 465 by 66, we get 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 147.0
If we subtract 462 from 465, we get 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 66

Advancing to step 5:
When dividing 37 by 66, we get 0 with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 1470.0
Subtract 0 from 37 to get 37.
Bring next digit (4) of the dividend behind the 37 and repeat the process: 374 / 66

Let's proceed to step 6:
374 divided by 66 is 5 with a remainder of 44.
The next digit of our result is 5. 
Result so far: 14705.0
Subtracting 330 from 374 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.

Going ahead to step 7:
The number 66 fits into 440 6 times, leaving a remainder of 44.
The next digit of our result is 6. 
Result so far: 14705.6
Deduct 396 from 440 and we're left 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.

Let's proceed to step 8:
66 can be fit into 440 6 times, resulting in a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 14705.66
The remainder is 44 after subtracting 396 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Our division results in 14705.66 with a remaining 0.044.
