We look at the division of 21960 by 24 
We want to divide 21960 by 24.

Step 1:
24 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
Deduct 0 from 2 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 24

Step 2:
21 divided by 24 is 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 24

Let's proceed to step 3:
If we divide 219 by 24, we get 9 and a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 216 away from 219, we end up with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 24

Step 4:
24 can be fit into 36 1 times, resulting in a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
The remainder is 12 after subtracting 24 from 36.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 24

Advancing to step 5:
24 goes into 120 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 915.0
If we take 120 away from 120, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 6:
0 divided by 24 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 915.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
24 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 915.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 915.0 and a remainder of 0.0.
