We divide 459912 by 30
We want to figure out the number of times 459912 can be divided by 30.

Step 1:
4 divided by 30 is 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.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 30

Going ahead to step 2:
30 can be fit into 45 1 times, resulting in a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 30 from 45 and we're left with 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 30

Advancing to step 3:
159 divided by 30 is 5 with a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 150 from 159, we get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 30

Going ahead to step 4:
30 can be fit into 99 3 times, resulting in a remainder of 9.
The next digit of our result is 3. 
Result so far: 153.0
Deduct 90 from 99 and we're left with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 30

Advancing to step 5:
The number 30 fits into 91 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 1533.0
If we take 90 away from 91, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 30

Going ahead to step 6:
30 can be fit into 12 0 times, resulting in a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 15330.0
Subtract 0 from 12 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
120 divided by 30 is 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 15330.4
Subtracting 120 from 120 leaves us 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 8:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15330.4
If we subtract 0 from 0, we 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.

Step 9:
When dividing 0 by 30, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15330.4
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.

The final result is 15330.4 with a remainder of 0.0.
