We're dividing 439399 by 30 
We want to figure out the number of times 439399 can be divided by 30.

Moving on to step 1:
4 divided by 30 is 0 with 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.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 30

On to step 2:
30 can be fit into 43 1 times, resulting in a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 13 after subtracting 30 from 43.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 30

Advancing to step 3:
If we divide 139 by 30, we get 4 and a remainder of 19.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we take 120 away from 139, we end up with 19.
Append the next digit (3) from the dividend to 19 and continue with: 193 / 30

Step 4:
When dividing 193 by 30, we get 6 with a remainder of 13.
Record the quotient 6 as the next digit in the result. 
Result so far: 146.0
Subtract 180 from 193 to get 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 30

Let's proceed to step 5:
30 can be fit into 139 4 times, resulting in a remainder of 19.
Put 4 as the next digit of the answer. 
Result so far: 1464.0
Subtract 120 from 139 to get 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 30

Moving on to step 6:
30 can be fit into 199 6 times, resulting in a remainder of 19.
The next digit of our result is 6. 
Result so far: 14646.0
The remainder is 19 after subtracting 180 from 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
30 goes into 190 6 times with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 14646.6
The remainder is 10 after subtracting 180 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
30 can be fit into 100 3 times, resulting in a remainder of 10.
The next digit of our result is 3. 
Result so far: 14646.63
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.

Moving on to step 9:
30 goes into 100 3 times with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 14646.633
If we subtract 90 from 100, we 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 quotient of the division is 14646.633, and the remainder is 0.001.
