We divide 450435 by 30
Let's see how many times 30 fits into 450435.

Step 1:
30 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 30

Advancing to step 2:
30 goes into 45 1 times with a remainder of 15.
Use 1 as the next digit of our solution. 
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

Let's proceed to step 3:
150 divided by 30 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 15.0
The remainder is 0 after subtracting 150 from 150.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 30

Advancing to step 4:
4 divided by 30 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 150.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 30

Advancing to step 5:
If we divide 43 by 30, we get 1 and a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 1501.0
The remainder is 13 after subtracting 30 from 43.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 30

Advancing to step 6:
30 can be fit into 135 4 times, resulting in a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 15014.0
If we take 120 away from 135, we end up 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.

Moving on to step 7:
150 divided by 30 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 15014.5
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:
If we divide 0 by 30, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15014.5
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:
0 divided by 30 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 15014.5
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.

Our division results in 15014.5 with a remaining 0.0.
