We look at the division of 458582 by 30 
We're looking to find how many times 30 goes into 458582.

Step 1:
30 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 30

On to step 2:
30 can be fit into 45 1 times, resulting in a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 30 from 45 to get 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 30

Going ahead to step 3:
The number 30 fits into 158 5 times, leaving a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we take 150 away from 158, we end up with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 30

Moving on to step 4:
If we divide 85 by 30, we get 2 and a remainder of 25.
Use 2 as the next digit of our solution. 
Result so far: 152.0
The remainder is 25 after subtracting 60 from 85.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 30

Moving on to step 5:
The number 30 fits into 258 8 times, leaving a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 1528.0
Deduct 240 from 258 and we're left with 18.
Take the next digit (2) from the dividend and append it to 18, then repeat: 182 / 30

Step 6:
The number 30 fits into 182 6 times, leaving a remainder of 2.
The next digit of our result is 6. 
Result so far: 15286.0
Subtract 180 from 182 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
When dividing 20 by 30, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 15286.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
200 divided by 30 is 6 with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 15286.06
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
The number 30 fits into 200 6 times, leaving a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 15286.066
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 15286.066, and the remainder is 0.002.
