We look at the division of 734273 by 30 
The aim is to understand the frequency of 30 in 734273.

Going ahead to step 1:
30 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 30

On to step 2:
30 can be fit into 73 2 times, resulting in a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 60 from 73 and we're left with 13.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 30

Advancing to step 3:
30 goes into 134 4 times with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 24.0
Subtracting 120 from 134 leaves us with 14.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 30

Let's proceed to step 4:
When dividing 142 by 30, we get 4 with a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 244.0
If we subtract 120 from 142, we get 22.
Append the next digit (7) from the dividend to 22 and continue with: 227 / 30

Let's proceed to step 5:
If we divide 227 by 30, we get 7 and a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 2447.0
Subtract 210 from 227 to get 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 30

On to step 6:
30 can be fit into 173 5 times, resulting in a remainder of 23.
Put 5 as the next digit of the answer. 
Result so far: 24475.0
Subtracting 150 from 173 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
The number 30 fits into 230 7 times, leaving a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 24475.7
The remainder is 20 after subtracting 210 from 230.
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.
The number 6 becomes the next digit in our result. 
Result so far: 24475.76
Subtract 180 from 200 to get 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 goes into 200 6 times with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 24475.766
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 24475.766 and a remainder of 0.002.
