28210 ÷ 99 
We want to divide 28210 by 99.

Going ahead to step 1:
If we divide 2 by 99, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 99

Going ahead to step 2:
28 divided by 99 is 0 with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Append the next digit (2) from the dividend to 28 and continue with: 282 / 99

Let's proceed to step 3:
282 divided by 99 is 2 with a remainder of 84.
The next digit of our result is 2. 
Result so far: 2.0
If we take 198 away from 282, we end up with 84.
Fetch the next digit (1) from the dividend, attach it to 84 and continue: 841 / 99

On to step 4:
841 divided by 99 is 8 with a remainder of 49.
The next digit of our result is 8. 
Result so far: 28.0
The remainder is 49 after subtracting 792 from 841.
Take the next digit (0) from the dividend and append it to 49, then repeat: 490 / 99

Let's proceed to step 5:
99 goes into 490 4 times with a remainder of 94.
The next digit of our result is 4. 
Result so far: 284.0
The remainder is 94 after subtracting 396 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 6:
940 divided by 99 is 9 with a remainder of 49.
Put 9 as the next digit of the answer. 
Result so far: 284.9
If we take 891 away from 940, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 7:
The number 99 fits into 490 4 times, leaving a remainder of 94.
The number 4 becomes the next digit in our result. 
Result so far: 284.94
If we subtract 396 from 490, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 8:
99 can be fit into 940 9 times, resulting in a remainder of 49.
The number 9 becomes the next digit in our result. 
Result so far: 284.949
The remainder is 49 after subtracting 891 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 9:
99 goes into 490 4 times with a remainder of 94.
The number 4 becomes the next digit in our result. 
Result so far: 284.9494
Subtract 396 from 490 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 10:
If we divide 940 by 99, we get 9 and a remainder of 49.
Put 9 as the next digit of the answer. 
Result so far: 284.94949
Deduct 891 from 940 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 11:
490 divided by 99 is 4 with a remainder of 94.
Put 4 as the next digit of the answer. 
Result so far: 284.949494
If we subtract 396 from 490, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 12:
The number 99 fits into 940 9 times, leaving a remainder of 49.
The next digit of our result is 9. 
Result so far: 284.9494949
Deduct 891 from 940 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 13:
490 divided by 99 is 4 with a remainder of 94.
The number 4 becomes the next digit in our result. 
Result so far: 284.94949494
If we subtract 396 from 490, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

After the division, we end up with 284.94949494 and a remainder of 9.4e-08.
