We're dividing 320997 by 15 
Let's see how many times 15 fits into 320997.

Going ahead to step 1:
When dividing 3 by 15, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 15

Going ahead to step 2:
15 can be fit into 32 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 30 from 32 to get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 15

Let's proceed to step 3:
If we divide 20 by 15, we get 1 and a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtracting 15 from 20 leaves us with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 15

Step 4:
When dividing 59 by 15, we get 3 with a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 213.0
The remainder is 14 after subtracting 45 from 59.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 15

Step 5:
If we divide 149 by 15, we get 9 and a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 2139.0
If we subtract 135 from 149, we get 14.
Append the next digit (7) from the dividend to 14 and continue with: 147 / 15

Moving on to step 6:
147 divided by 15 is 9 with a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 21399.0
If we take 135 away from 147, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
If we divide 120 by 15, we get 8 and a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 21399.8
Subtract 120 from 120 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.

Advancing to step 8:
15 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 21399.8
If we take 0 away from 0, we end up 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.

Step 9:
If we divide 0 by 15, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 21399.8
The remainder is 0 after subtracting 0 from 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 21399.8 with a balance of 0.0.
