450299 ÷ 30 
We're looking to find how many times 30 goes into 450299.

Going ahead to 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.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 30

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
The remainder is 15 after subtracting 30 from 45.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 30

Moving on to step 3:
The number 30 fits into 150 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 150 from 150 leaves us with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 30

Let's proceed to step 4:
30 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 150.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 30

Going ahead to step 5:
The number 30 fits into 29 0 times, leaving a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 1500.0
Subtract 0 from 29 to get 29.
Append the next digit (9) from the dividend to 29 and continue with: 299 / 30

Advancing to step 6:
30 goes into 299 9 times with a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 15009.0
Subtracting 270 from 299 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 7:
The number 30 fits into 290 9 times, leaving a remainder of 20.
The next digit of our result is 9. 
Result so far: 15009.9
Deduct 270 from 290 and we're left 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.

On to step 8:
If we divide 200 by 30, we get 6 and a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 15009.96
Deduct 180 from 200 and we're left 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.

Let's proceed to step 9:
200 divided by 30 is 6 with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 15009.966
Subtract 180 from 200 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.

Our division results in 15009.966 with a remaining 0.002.
