We look at the division of 450474 by 30 
We want to divide 450474 by 30.

Going ahead to step 1:
4 divided by 30 is 0 with 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.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 30

Let's proceed to step 2:
45 divided by 30 is 1 with 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.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 30

Going ahead to step 3:
If we divide 150 by 30, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 150 from 150 leaves us with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 30

Step 4:
The number 30 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 150.0
If we subtract 0 from 4, we get 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 30

Step 5:
47 divided by 30 is 1 with a remainder of 17.
The next digit of our result is 1. 
Result so far: 1501.0
Subtract 30 from 47 to get 17.
Include the next digit (4) from the dividend after 17, then repeat: 174 / 30

Step 6:
30 goes into 174 5 times with a remainder of 24.
Write down 5 as next digit of the result. 
Result so far: 15015.0
If we take 150 away from 174, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
30 goes into 240 8 times with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 15015.8
The remainder is 0 after subtracting 240 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On 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: 15015.8
Subtract 0 from 0 to 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.

Moving on to step 9:
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: 15015.8
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.

The final outcome is 15015.8, with a leftover of 0.0.
