425290 ÷ 30 
The aim is to understand the frequency of 30 in 425290.

Let's proceed to step 1:
30 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 30

Let's proceed to step 2:
30 goes into 42 1 times with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 30 away from 42, we end up with 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 30

Let's proceed to step 3:
125 divided by 30 is 4 with a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtract 120 from 125 to get 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 30

Step 4:
If we divide 52 by 30, we get 1 and a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 141.0
If we take 30 away from 52, we end up with 22.
Include the next digit (9) from the dividend after 22, then repeat: 229 / 30

Going ahead to step 5:
If we divide 229 by 30, we get 7 and a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 1417.0
If we subtract 210 from 229, we get 19.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 30

Going ahead to step 6:
When dividing 190 by 30, we get 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 14176.0
Subtract 180 from 190 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
When dividing 100 by 30, we get 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 14176.3
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
30 goes into 100 3 times with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 14176.33
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 14176.33 with a balance of 0.01.
