We look at the division of 758481 by 30 
The aim is to understand the frequency of 30 in 758481.

Advancing to step 1:
When dividing 7 by 30, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 30

Moving on to step 2:
30 can be fit into 75 2 times, resulting in a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 60 from 75 leaves us with 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 30

Going ahead to step 3:
30 goes into 158 5 times with a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Deduct 150 from 158 and we're left with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 30

On to step 4:
30 can be fit into 84 2 times, resulting in a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 252.0
If we subtract 60 from 84, we get 24.
Grab the next digit (8) from the dividend, add it to 24, then carry on: 248 / 30

Step 5:
30 can be fit into 248 8 times, resulting in a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 2528.0
Subtract 240 from 248 to get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 30

Let's proceed to step 6:
When dividing 81 by 30, we get 2 with a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 25282.0
The remainder is 21 after subtracting 60 from 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
30 can be fit into 210 7 times, resulting in a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 25282.7
The remainder is 0 after subtracting 210 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
When dividing 0 by 30, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 25282.7
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 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 25282.7
The remainder is 0 after subtracting 0 from 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 25282.7, and the remainder is 0.0.
