We divide 304644 by 30
The aim is to understand the frequency of 30 in 304644.

Step 1:
3 divided by 30 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 30

Moving on to step 2:
If we divide 30 by 30, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 30 away from 30, we end up with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 30

Step 3:
If we divide 4 by 30, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 30

Let's proceed to step 4:
If we divide 46 by 30, we get 1 and a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 101.0
If we take 30 away from 46, we end up with 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 30

Advancing to step 5:
When dividing 164 by 30, we get 5 with a remainder of 14.
The next digit of our result is 5. 
Result so far: 1015.0
Deduct 150 from 164 and we're left with 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 30

Advancing to step 6:
30 can be fit into 144 4 times, resulting in a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 10154.0
Deduct 120 from 144 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 7:
30 goes into 240 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 10154.8
Deduct 240 from 240 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.

Step 8:
30 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10154.8
If we subtract 0 from 0, we 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.

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: 10154.8
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.

After the division, we end up with 10154.8 and a remainder of 0.0.
