750672 ÷ 30 
The aim is to understand the frequency of 30 in 750672.

Step 1:
7 divided by 30 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 30

Advancing to step 2:
The number 30 fits into 75 2 times, leaving a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 60 from 75 and we're left with 15.
Fetch the next digit (0) from the dividend, attach it to 15 and continue: 150 / 30

Step 3:
30 goes into 150 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtracting 150 from 150 leaves us with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 30

Let's proceed to step 4:
The number 30 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 250.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 30

Moving on to step 5:
The number 30 fits into 67 2 times, leaving a remainder of 7.
The next digit of our result is 2. 
Result so far: 2502.0
Subtract 60 from 67 to get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 30

Step 6:
The number 30 fits into 72 2 times, leaving a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 25022.0
The remainder is 12 after subtracting 60 from 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
If we divide 120 by 30, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 25022.4
Subtract 120 from 120 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.

Advancing to step 8:
The number 30 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 25022.4
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:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 25022.4
Deduct 0 from 0 and we're left 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.

Our division results in 25022.4 with a remaining 0.0.
