We divide 989200 by 30
The aim is to understand the frequency of 30 in 989200.

On to step 1:
9 divided by 30 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 30

Moving on to step 2:
If we divide 98 by 30, we get 3 and a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 90 from 98 and we're left with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 30

Advancing to step 3:
30 goes into 89 2 times with a remainder of 29.
Put 2 as the next digit of the answer. 
Result so far: 32.0
Subtract 60 from 89 to get 29.
Bring next digit (2) of the dividend behind the 29 and repeat the process: 292 / 30

Let's proceed to step 4:
If we divide 292 by 30, we get 9 and a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 329.0
Subtracting 270 from 292 leaves us with 22.
Append the next digit (0) from the dividend to 22 and continue with: 220 / 30

Advancing to step 5:
If we divide 220 by 30, we get 7 and a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 3297.0
Subtracting 210 from 220 leaves us with 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 30

Going ahead to step 6:
30 can be fit into 100 3 times, resulting in a remainder of 10.
The next digit of our result is 3. 
Result so far: 32973.0
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
100 divided by 30 is 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 32973.3
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
When dividing 100 by 30, we get 3 with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 32973.33
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 32973.33 with a remaining 0.01.
