We look at the division of 320494 by 15 
We want to divide 320494 by 15.

On to step 1:
15 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 15

Step 2:
32 divided by 15 is 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 30 from 32, we get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 15

Going ahead to step 3:
15 can be fit into 20 1 times, resulting in a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Deduct 15 from 20 and we're left with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 15

Moving on to step 4:
54 divided by 15 is 3 with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 213.0
Subtracting 45 from 54 leaves us with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 15

Advancing to step 5:
When dividing 99 by 15, we get 6 with a remainder of 9.
The next digit of our result is 6. 
Result so far: 2136.0
The remainder is 9 after subtracting 90 from 99.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 15

Advancing to step 6:
15 can be fit into 94 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 21366.0
Subtract 90 from 94 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
15 goes into 40 2 times with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 21366.2
If we take 30 away from 40, we end up 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.

Going ahead to step 8:
15 can be fit into 100 6 times, resulting in a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 21366.26
Deduct 90 from 100 and we're left 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 9:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 21366.266
The remainder is 10 after subtracting 90 from 100.
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 result is 21366.266 with a remainder of 0.001.
