We divide 249804 by 30
The aim is to understand the frequency of 30 in 249804.

Let's proceed to step 1:
If we divide 2 by 30, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 30

Advancing to step 2:
If we divide 24 by 30, we get 0 and a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 24 to get 24.
Bring next digit (9) of the dividend behind the 24 and repeat the process: 249 / 30

On to step 3:
When dividing 249 by 30, we get 8 with a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 240 from 249 leaves us with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 30

Step 4:
The number 30 fits into 98 3 times, leaving a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 83.0
If we take 90 away from 98, we end up with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 30

Going ahead to step 5:
30 can be fit into 80 2 times, resulting in a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 832.0
Deduct 60 from 80 and we're left with 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 30

Going ahead to step 6:
The number 30 fits into 204 6 times, leaving a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 8326.0
If we subtract 180 from 204, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 7:
The number 30 fits into 240 8 times, leaving a remainder of 0.
The next digit of our result is 8. 
Result so far: 8326.8
Subtract 240 from 240 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.

Going ahead to step 8:
30 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 8326.8
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.

Advancing to step 9:
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: 8326.8
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.

After the division, we end up with 8326.8 and a remainder of 0.0.
