We look at the division of 439905 by 30 
We want to divide 439905 by 30.

Let's proceed to step 1:
30 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 30

Let's proceed to step 2:
The number 30 fits into 43 1 times, leaving a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 30 from 43 and we're left with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 30

Moving on to step 3:
When dividing 139 by 30, we get 4 with a remainder of 19.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtracting 120 from 139 leaves us with 19.
Take the next digit (9) from the dividend and append it to 19, then repeat: 199 / 30

Step 4:
30 goes into 199 6 times with a remainder of 19.
Use 6 as the next digit of our solution. 
Result so far: 146.0
Subtracting 180 from 199 leaves us with 19.
Grab the next digit (0) from the dividend, add it to 19, then carry on: 190 / 30

Moving on to step 5:
If we divide 190 by 30, we get 6 and a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 1466.0
If we subtract 180 from 190, we get 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 30

On to step 6:
The number 30 fits into 105 3 times, leaving a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 14663.0
Subtracting 90 from 105 leaves us 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.

Advancing to step 7:
The number 30 fits into 150 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 14663.5
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.

Going ahead to step 8:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 14663.5
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.

On to step 9:
30 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 14663.5
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.

The final result is 14663.5 with a remainder of 0.0.
