450220 divided by 30 
The aim is to understand the frequency of 30 in 450220.

Advancing to step 1:
When dividing 4 by 30, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 30

On to step 2:
30 can be fit into 45 1 times, resulting in a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 30 from 45, we get 15.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 30

Let's proceed to step 3:
30 goes into 150 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 150 from 150, we get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 30

Step 4:
30 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 150.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 30

Step 5:
30 can be fit into 22 0 times, resulting in a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 1500.0
The remainder is 22 after subtracting 0 from 22.
Include the next digit (0) from the dividend after 22, then repeat: 220 / 30

Moving on to step 6:
The number 30 fits into 220 7 times, leaving a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 15007.0
Subtract 210 from 220 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.

Advancing to step 7:
100 divided by 30 is 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 15007.3
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
30 can be fit into 100 3 times, resulting in a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 15007.33
If we subtract 90 from 100, we 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.

The quotient of the division is 15007.33, and the remainder is 0.01.
