Let's divide 306397 by 30
Let's see how many times 30 fits into 306397.

Moving on to step 1:
3 divided by 30 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 30

Going ahead to step 2:
30 divided by 30 is 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 30 from 30 and we're left with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 30

Going ahead to step 3:
The number 30 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 30

Step 4:
30 goes into 63 2 times with a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 102.0
If we subtract 60 from 63, we get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 30

Step 5:
30 goes into 39 1 times with a remainder of 9.
The next digit of our result is 1. 
Result so far: 1021.0
Subtract 30 from 39 to get 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 30

Going ahead to step 6:
30 can be fit into 97 3 times, resulting in a remainder of 7.
The next digit of our result is 3. 
Result so far: 10213.0
Deduct 90 from 97 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
The number 30 fits into 70 2 times, leaving a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 10213.2
Subtracting 60 from 70 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.

On to step 8:
If we divide 100 by 30, we get 3 and a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 10213.23
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.

Advancing to step 9:
30 goes into 100 3 times with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 10213.233
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.

After the division, we end up with 10213.233 and a remainder of 0.001.
