We look at the division of 459135 by 30 
We're looking to find how many times 30 goes into 459135.

Step 1:
30 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 30

Moving on to step 2:
When dividing 45 by 30, we get 1 with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 30 from 45 leaves us with 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 30

On to step 3:
If we divide 159 by 30, we get 5 and a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 150 from 159 to get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 30

Moving on to step 4:
When dividing 91 by 30, we get 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 153.0
Deduct 90 from 91 and we're left with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 30

Step 5:
The number 30 fits into 13 0 times, leaving a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 1530.0
The remainder is 13 after subtracting 0 from 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 30

Advancing to step 6:
30 goes into 135 4 times with a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 15304.0
Deduct 120 from 135 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
The number 30 fits into 150 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 15304.5
Deduct 150 from 150 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.

Advancing to step 8:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 15304.5
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.

Advancing to step 9:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15304.5
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 outcome is 15304.5, with a leftover of 0.0.
