We're dividing 726918 by 30 
The aim is to understand the frequency of 30 in 726918.

Let's proceed to step 1:
7 divided by 30 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 30

Moving on to step 2:
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: 2.0
Subtracting 60 from 72 leaves us with 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 30

Moving on to step 3:
If we divide 126 by 30, we get 4 and a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 24.0
Deduct 120 from 126 and we're left with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 30

Going ahead to step 4:
If we divide 69 by 30, we get 2 and a remainder of 9.
The next digit of our result is 2. 
Result so far: 242.0
Deduct 60 from 69 and we're left with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 30

Let's proceed to step 5:
30 can be fit into 91 3 times, resulting in a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 2423.0
Deduct 90 from 91 and we're left with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 30

Going ahead to step 6:
When dividing 18 by 30, we get 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 24230.0
Subtract 0 from 18 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
180 divided by 30 is 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 24230.6
If we take 180 away from 180, we end up 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.

Advancing 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: 24230.6
If we take 0 away from 0, we end up 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.

On to step 9:
If we divide 0 by 30, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 24230.6
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.

After the division, we end up with 24230.6 and a remainder of 0.0.
