Let's divide 4621209 by 30
The aim is to understand the frequency of 30 in 4621209.

Going ahead to step 1:
30 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 30

Going ahead to step 2:
46 divided by 30 is 1 with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 30 from 46 and we're left with 16.
Include the next digit (2) from the dividend after 16, then repeat: 162 / 30

On to step 3:
The number 30 fits into 162 5 times, leaving a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 150 from 162 to get 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 30

On to step 4:
The number 30 fits into 121 4 times, leaving a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 154.0
If we subtract 120 from 121, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 30

Moving on to step 5:
12 divided by 30 is 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 1540.0
If we subtract 0 from 12, we get 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 30

Step 6:
30 can be fit into 120 4 times, resulting in a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 15404.0
If we subtract 120 from 120, we get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 30

Step 7:
The number 30 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 154040.0
The remainder is 9 after subtracting 0 from 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 8:
30 can be fit into 90 3 times, resulting in a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 154040.3
Deduct 90 from 90 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.

Going ahead to step 9:
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: 154040.3
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.

Step 10:
If we divide 0 by 30, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 154040.3
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.

In conclusion, the division gives 154040.3 with a balance of 0.0.
