We look at the division of 898748 by 30 
The aim is to understand the frequency of 30 in 898748.

Advancing to step 1:
The number 30 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 30

Let's proceed to step 2:
30 can be fit into 89 2 times, resulting in a remainder of 29.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 60 from 89 to get 29.
Append the next digit (8) from the dividend to 29 and continue with: 298 / 30

Moving on to step 3:
298 divided by 30 is 9 with a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 29.0
If we subtract 270 from 298, we get 28.
Append the next digit (7) from the dividend to 28 and continue with: 287 / 30

Let's proceed to step 4:
When dividing 287 by 30, we get 9 with a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 299.0
Subtract 270 from 287 to get 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 30

Advancing to step 5:
174 divided by 30 is 5 with a remainder of 24.
The number 5 becomes the next digit in our result. 
Result so far: 2995.0
If we take 150 away from 174, we end up with 24.
Include the next digit (8) from the dividend after 24, then repeat: 248 / 30

Step 6:
30 goes into 248 8 times with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 29958.0
If we subtract 240 from 248, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
When dividing 80 by 30, we get 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 29958.2
Subtracting 60 from 80 leaves us 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.

Let's proceed to step 8:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 29958.26
Subtracting 180 from 200 leaves us 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 9:
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: 29958.266
Deduct 180 from 200 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.

The final outcome is 29958.266, with a leftover of 0.002.
