396899 divided by 30 
Our goal is to divide 396899 by 30.

Let's proceed to step 1:
3 divided by 30 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 30

Going ahead to step 2:
If we divide 39 by 30, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 30 from 39 to get 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 30

Going ahead to step 3:
The number 30 fits into 96 3 times, leaving a remainder of 6.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 90 from 96, we get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 30

Let's proceed to step 4:
The number 30 fits into 68 2 times, leaving a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 132.0
Subtract 60 from 68 to get 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 30

On to step 5:
30 can be fit into 89 2 times, resulting in a remainder of 29.
The next digit of our result is 2. 
Result so far: 1322.0
Subtract 60 from 89 to get 29.
Fetch the next digit (9) from the dividend, attach it to 29 and continue: 299 / 30

Advancing to step 6:
When dividing 299 by 30, we get 9 with a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 13229.0
Subtracting 270 from 299 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 7:
290 divided by 30 is 9 with a remainder of 20.
The next digit of our result is 9. 
Result so far: 13229.9
If we subtract 270 from 290, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
The number 30 fits into 200 6 times, leaving a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 13229.96
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
If we divide 200 by 30, we get 6 and a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 13229.966
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 13229.966, with a leftover of 0.002.
