We look at the division of 383397 by 30 
Our goal is to divide 383397 by 30.

On to step 1:
The number 30 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 30

Advancing to step 2:
30 goes into 38 1 times with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 30 from 38 to get 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 30

Advancing to step 3:
30 goes into 83 2 times with a remainder of 23.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 60 away from 83, we end up with 23.
Take the next digit (3) from the dividend and append it to 23, then repeat: 233 / 30

On to step 4:
The number 30 fits into 233 7 times, leaving a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 127.0
If we take 210 away from 233, we end up with 23.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 30

Moving on to step 5:
The number 30 fits into 239 7 times, leaving a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 1277.0
If we subtract 210 from 239, we get 29.
Bring next digit (7) of the dividend behind the 29 and repeat the process: 297 / 30

On to step 6:
The number 30 fits into 297 9 times, leaving a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 12779.0
If we subtract 270 from 297, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 7:
If we divide 270 by 30, we get 9 and a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 12779.9
Deduct 270 from 270 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.

Advancing to step 8:
The number 30 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 12779.9
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:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12779.9
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.

In conclusion, the division gives 12779.9 with a balance of 0.0.
