28221 divided by 9 
We're looking to find how many times 9 goes into 28221.

Going ahead to step 1:
9 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 9

Moving on to step 2:
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: 3.0
Subtracting 27 from 28 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 9

Step 3:
12 divided by 9 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 31.0
If we subtract 9 from 12, we get 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 9

Step 4:
9 goes into 32 3 times with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 313.0
Subtracting 27 from 32 leaves us with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 9

Moving on to step 5:
9 goes into 51 5 times with a remainder of 6.
The next digit of our result is 5. 
Result so far: 3135.0
If we subtract 45 from 51, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 6:
9 can be fit into 60 6 times, resulting in a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 3135.6
If we subtract 54 from 60, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
9 can be fit into 60 6 times, resulting in a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 3135.66
The remainder is 6 after subtracting 54 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

In conclusion, the division gives 3135.66 with a balance of 0.006.
