Let's divide 744925 by 30
The aim is to understand the frequency of 30 in 744925.

On to step 1:
If we divide 7 by 30, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 30

Moving on to step 2:
When dividing 74 by 30, we get 2 with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 60 from 74 and we're left with 14.
Bring next digit (4) of the dividend behind the 14 and repeat the process: 144 / 30

Let's proceed to step 3:
If we divide 144 by 30, we get 4 and a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 24.0
Subtract 120 from 144 to get 24.
Include the next digit (9) from the dividend after 24, then repeat: 249 / 30

Advancing to step 4:
If we divide 249 by 30, we get 8 and a remainder of 9.
The next digit of our result is 8. 
Result so far: 248.0
The remainder is 9 after subtracting 240 from 249.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 30

Step 5:
If we divide 92 by 30, we get 3 and a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 2483.0
Subtract 90 from 92 to get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 30

Advancing to step 6:
If we divide 25 by 30, we get 0 and a remainder of 25.
The next digit of our result is 0. 
Result so far: 24830.0
If we subtract 0 from 25, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 7:
When dividing 250 by 30, we get 8 with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 24830.8
Deduct 240 from 250 and we're left 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.

Let's proceed to step 8:
30 goes into 100 3 times with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 24830.83
If we subtract 90 from 100, we 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.

Moving on to step 9:
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: 24830.833
If we take 90 away from 100, we end up 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.

The final result is 24830.833 with a remainder of 0.001.
