We look at the division of 848664 by 30 
The aim is to understand the frequency of 30 in 848664.

Step 1:
30 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 30

Let's proceed to step 2:
If we divide 84 by 30, we get 2 and a remainder of 24.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 60 from 84, we get 24.
Fetch the next digit (8) from the dividend, attach it to 24 and continue: 248 / 30

Going ahead to step 3:
When dividing 248 by 30, we get 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 28.0
Subtracting 240 from 248 leaves us with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 30

Let's proceed to step 4:
30 can be fit into 86 2 times, resulting in a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 282.0
If we subtract 60 from 86, we get 26.
Take the next digit (6) from the dividend and append it to 26, then repeat: 266 / 30

On to step 5:
30 can be fit into 266 8 times, resulting in a remainder of 26.
The next digit of our result is 8. 
Result so far: 2828.0
Subtract 240 from 266 to get 26.
Append the next digit (4) from the dividend to 26 and continue with: 264 / 30

On to step 6:
The number 30 fits into 264 8 times, leaving a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 28288.0
Deduct 240 from 264 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 7:
30 goes into 240 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 28288.8
If we subtract 240 from 240, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
30 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 28288.8
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
If we divide 0 by 30, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 28288.8
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 28288.8 with a remaining 0.0.
