480630 ÷ 30 
The aim is to understand the frequency of 30 in 480630.

Moving on to step 1:
4 divided by 30 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 30

Going ahead to step 2:
30 can be fit into 48 1 times, resulting in a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 30 from 48 and we're left with 18.
Append the next digit (0) from the dividend to 18 and continue with: 180 / 30

Moving on to step 3:
If we divide 180 by 30, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 16.0
If we subtract 180 from 180, we get 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 30

Advancing to step 4:
If we divide 6 by 30, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 160.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 30

Let's proceed to step 5:
63 divided by 30 is 2 with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 1602.0
If we take 60 away from 63, we end up with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 30

On to step 6:
The number 30 fits into 30 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 16021.0
Deduct 30 from 30 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.

Let's proceed to step 7:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 16021.0
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.

Step 8:
30 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 16021.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 16021.0, with a leftover of 0.0.
