Let's divide 28891 by 9
Our goal is to divide 28891 by 9.

On to step 1:
9 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 9

Advancing to step 2:
If we divide 28 by 9, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 27 from 28 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 9

Advancing to step 3:
9 goes into 18 2 times with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
If we take 18 away from 18, we end up with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 9

Step 4:
9 can be fit into 9 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 321.0
Subtracting 9 from 9 leaves us with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 9

Advancing to step 5:
If we divide 1 by 9, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 3210.0
Deduct 0 from 1 and we're left 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.

Advancing to step 6:
If we divide 10 by 9, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 3210.1
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:
If we divide 10 by 9, we get 1 and a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 3210.11
Deduct 9 from 10 and we're left 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 final outcome is 3210.11, with a leftover of 0.001.
