We're dividing 72129 by 24 
Let's see how many times 24 fits into 72129.

Going ahead to step 1:
When dividing 7 by 24, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 24

Step 2:
If we divide 72 by 24, we get 3 and a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 72 away from 72, we end up with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 24

Step 3:
1 divided by 24 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
If we subtract 0 from 1, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 24

Going ahead to step 4:
12 divided by 24 is 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 300.0
If we subtract 0 from 12, we get 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 24

Let's proceed to step 5:
The number 24 fits into 129 5 times, leaving a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 3005.0
If we take 120 away from 129, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 6:
90 divided by 24 is 3 with a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 3005.3
If we subtract 72 from 90, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
24 goes into 180 7 times with a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 3005.37
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
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: 3005.375
If we subtract 120 from 120, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
0 divided by 24 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3005.375
Subtract 0 from 0 to get 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 10:
When dividing 0 by 24, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3005.375
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 3005.375 with a remaining 0.0.
