450850 divided by 30 
We want to divide 450850 by 30.

Step 1:
If we divide 4 by 30, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 30

Let's proceed to step 2:
45 divided by 30 is 1 with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 30 from 45 to get 15.
Fetch the next digit (0) from the dividend, attach it to 15 and continue: 150 / 30

Let's proceed 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.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 30

Let's proceed to step 4:
When dividing 8 by 30, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 150.0
Subtract 0 from 8 to get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 30

Advancing to step 5:
When dividing 85 by 30, we get 2 with a remainder of 25.
Record the quotient 2 as the next digit in the result. 
Result so far: 1502.0
The remainder is 25 after subtracting 60 from 85.
Bring next digit (0) of the dividend behind the 25 and repeat the process: 250 / 30

Advancing to step 6:
If we divide 250 by 30, we get 8 and a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 15028.0
Deduct 240 from 250 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
If we divide 100 by 30, we get 3 and a remainder of 10.
The next digit of our result is 3. 
Result so far: 15028.3
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
The number 30 fits into 100 3 times, leaving a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 15028.33
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 15028.33, with a leftover of 0.01.
