We look at the division of 320988 by 15 
We want to divide 320988 by 15.

Advancing to step 1:
15 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 15

Step 2:
When dividing 32 by 15, we get 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 30 from 32, we get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 15

On to step 3:
20 divided by 15 is 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Deduct 15 from 20 and we're left with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 15

On to step 4:
15 can be fit into 59 3 times, resulting in a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 213.0
Subtracting 45 from 59 leaves us with 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 15

On to step 5:
15 goes into 148 9 times with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 2139.0
If we take 135 away from 148, we end up with 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 15

Let's proceed to step 6:
138 divided by 15 is 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 21399.0
Deduct 135 from 138 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
If we divide 30 by 15, we get 2 and a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 21399.2
Deduct 30 from 30 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.

Moving on to step 8:
If we divide 0 by 15, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 21399.2
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.

Moving on to step 9:
If we divide 0 by 15, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 21399.2
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.

Our division results in 21399.2 with a remaining 0.0.
