We look at the division of 838446 by 30 
The aim is to understand the frequency of 30 in 838446.

On to step 1:
30 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 30

Advancing to step 2:
83 divided by 30 is 2 with a remainder of 23.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 60 from 83 leaves us with 23.
Take the next digit (8) from the dividend and append it to 23, then repeat: 238 / 30

Step 3:
238 divided by 30 is 7 with a remainder of 28.
Use 7 as the next digit of our solution. 
Result so far: 27.0
Subtracting 210 from 238 leaves us with 28.
Fetch the next digit (4) from the dividend, attach it to 28 and continue: 284 / 30

On to step 4:
30 can be fit into 284 9 times, resulting in a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 279.0
If we take 270 away from 284, we end up with 14.
Bring next digit (4) of the dividend behind the 14 and repeat the process: 144 / 30

On to step 5:
The number 30 fits into 144 4 times, leaving a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 2794.0
If we subtract 120 from 144, we get 24.
Fetch the next digit (6) from the dividend, attach it to 24 and continue: 246 / 30

Moving on to step 6:
30 goes into 246 8 times with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 27948.0
Subtract 240 from 246 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
60 divided by 30 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 27948.2
The remainder is 0 after subtracting 60 from 60.
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:
When dividing 0 by 30, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 27948.2
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:
When dividing 0 by 30, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 27948.2
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.

In conclusion, the division gives 27948.2 with a balance of 0.0.
