We look at the division of 24123 by 9 
Our goal is to divide 24123 by 9.

Going ahead to step 1:
The number 9 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 9

Step 2:
24 divided by 9 is 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 18 from 24, we get 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 9

Going ahead to step 3:
If we divide 61 by 9, we get 6 and a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Subtract 54 from 61 to get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 9

Going ahead to step 4:
72 divided by 9 is 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 268.0
If we subtract 72 from 72, we get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 9

On to step 5:
The number 9 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 2680.0
If we subtract 0 from 3, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 6:
9 can be fit into 30 3 times, resulting in a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 2680.3
The remainder is 3 after subtracting 27 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
If we divide 30 by 9, we get 3 and a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 2680.33
If we subtract 27 from 30, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

In conclusion, the division gives 2680.33 with a balance of 0.003.
