We look at the division of 997437 by 30 
The aim is to understand the frequency of 30 in 997437.

Advancing to step 1:
30 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 30

Step 2:
30 can be fit into 99 3 times, resulting in a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 9 after subtracting 90 from 99.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 30

Moving on to step 3:
The number 30 fits into 97 3 times, leaving a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 33.0
If we subtract 90 from 97, we get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 30

On to step 4:
74 divided by 30 is 2 with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 332.0
Subtracting 60 from 74 leaves us with 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 30

Moving on to step 5:
30 goes into 143 4 times with a remainder of 23.
Write down 4 as next digit of the result. 
Result so far: 3324.0
If we take 120 away from 143, we end up with 23.
Include the next digit (7) from the dividend after 23, then repeat: 237 / 30

Advancing to step 6:
30 can be fit into 237 7 times, resulting in a remainder of 27.
The next digit of our result is 7. 
Result so far: 33247.0
Subtract 210 from 237 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 7:
When dividing 270 by 30, we get 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 33247.9
Subtract 270 from 270 to 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.

Going ahead to step 8:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 33247.9
Subtract 0 from 0 to 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.

Moving on to step 9:
If we divide 0 by 30, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 33247.9
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 33247.9, and the remainder is 0.0.
