We're dividing 974897 by 30 
The aim is to understand the frequency of 30 in 974897.

On to step 1:
9 divided by 30 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 30

Advancing to step 2:
30 can be fit into 97 3 times, resulting in a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 90 from 97 to get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 30

Let's proceed to step 3:
30 can be fit into 74 2 times, resulting in a remainder of 14.
The next digit of our result is 2. 
Result so far: 32.0
Subtract 60 from 74 to get 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 30

Let's proceed to step 4:
The number 30 fits into 148 4 times, leaving a remainder of 28.
The next digit of our result is 4. 
Result so far: 324.0
Subtract 120 from 148 to get 28.
Bring next digit (9) of the dividend behind the 28 and repeat the process: 289 / 30

Step 5:
If we divide 289 by 30, we get 9 and a remainder of 19.
The next digit of our result is 9. 
Result so far: 3249.0
If we take 270 away from 289, we end up with 19.
Append the next digit (7) from the dividend to 19 and continue with: 197 / 30

Let's proceed to step 6:
30 can be fit into 197 6 times, resulting in a remainder of 17.
The next digit of our result is 6. 
Result so far: 32496.0
If we take 180 away from 197, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
30 can be fit into 170 5 times, resulting in a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 32496.5
Subtracting 150 from 170 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 goes into 200 6 times with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 32496.56
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:
30 can be fit into 200 6 times, resulting in a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 32496.566
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.

Our division results in 32496.566 with a remaining 0.002.
