We're dividing 664976 by 30 
The aim is to understand the frequency of 30 in 664976.

Step 1:
30 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 30

Step 2:
30 goes into 66 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 60 away from 66, we end up with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 30

Moving on to step 3:
When dividing 64 by 30, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtracting 60 from 64 leaves us with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 30

Going ahead to step 4:
30 goes into 49 1 times with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 221.0
If we take 30 away from 49, we end up with 19.
Grab the next digit (7) from the dividend, add it to 19, then carry on: 197 / 30

Let's proceed to step 5:
If we divide 197 by 30, we get 6 and a remainder of 17.
Put 6 as the next digit of the answer. 
Result so far: 2216.0
Subtracting 180 from 197 leaves us with 17.
Append the next digit (6) from the dividend to 17 and continue with: 176 / 30

Let's proceed to step 6:
The number 30 fits into 176 5 times, leaving a remainder of 26.
The next digit of our result is 5. 
Result so far: 22165.0
If we take 150 away from 176, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 7:
30 goes into 260 8 times with a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 22165.8
Deduct 240 from 260 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.

Advancing to step 8:
When dividing 200 by 30, we get 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 22165.86
If we subtract 180 from 200, 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.

Moving on to step 9:
200 divided by 30 is 6 with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 22165.866
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 22165.866 with a remainder of 0.002.
