20989 ÷ 9 
Our goal is to divide 20989 by 9.

Advancing to step 1:
If we divide 2 by 9, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 9

Step 2:
When dividing 20 by 9, 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 18 from 20, we get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 9

Step 3:
When dividing 29 by 9, we get 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 23.0
Deduct 27 from 29 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 9

Moving on to step 4:
The number 9 fits into 28 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 233.0
The remainder is 1 after subtracting 27 from 28.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 9

Let's proceed to step 5:
9 goes into 19 2 times with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2332.0
If we take 18 away from 19, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 6:
The number 9 fits into 10 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 2332.1
If we take 9 away from 10, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
9 can be fit into 10 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 2332.11
Subtracting 9 from 10 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 2332.11, and the remainder is 0.001.
