21100 ÷ 24 
We want to divide 21100 by 24.

Moving on to step 1:
24 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 24

On to step 2:
When dividing 21 by 24, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Fetch the next digit (1) from the dividend, attach it to 21 and continue: 211 / 24

Let's proceed to step 3:
When dividing 211 by 24, we get 8 with a remainder of 19.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 192 from 211, we get 19.
Grab the next digit (0) from the dividend, add it to 19, then carry on: 190 / 24

Moving on to step 4:
190 divided by 24 is 7 with a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 87.0
The remainder is 22 after subtracting 168 from 190.
Include the next digit (0) from the dividend after 22, then repeat: 220 / 24

On to step 5:
24 goes into 220 9 times with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 879.0
If we subtract 216 from 220, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 6:
40 divided by 24 is 1 with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 879.1
The remainder is 16 after subtracting 24 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
When dividing 160 by 24, we get 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 879.16
Subtracting 144 from 160 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
24 can be fit into 160 6 times, resulting in a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 879.166
If we take 144 away from 160, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 879.166 with a remainder of 0.0016.
