Let's divide 99439 by 30
We want to divide 99439 by 30.

Going ahead to step 1:
30 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 30

Moving on to step 2:
The number 30 fits into 99 3 times, leaving a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 90 away from 99, we end up with 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 30

Going ahead to step 3:
The number 30 fits into 94 3 times, leaving a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 33.0
If we subtract 90 from 94, we get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 30

Let's proceed to step 4:
The number 30 fits into 43 1 times, leaving a remainder of 13.
The next digit of our result is 1. 
Result so far: 331.0
If we take 30 away from 43, we end up with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 30

Going ahead to step 5:
If we divide 139 by 30, we get 4 and a remainder of 19.
The number 4 becomes the next digit in our result. 
Result so far: 3314.0
If we subtract 120 from 139, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 6:
The number 30 fits into 190 6 times, leaving a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 3314.6
Subtracting 180 from 190 leaves us 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.

Moving on to step 7:
30 goes into 100 3 times with a remainder of 10.
The next digit of our result is 3. 
Result so far: 3314.63
Subtracting 90 from 100 leaves us 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.

Moving on 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: 3314.633
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 final outcome is 3314.633, with a leftover of 0.001.
