We're dividing 129672 by 24 
Let's see how many times 24 fits into 129672.

Going ahead to step 1:
1 divided by 24 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
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

Advancing to step 2:
If we divide 12 by 24, we get 0 and a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 24

Moving on to step 3:
The number 24 fits into 129 5 times, leaving a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 120 from 129 and we're left with 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 24

On to step 4:
24 can be fit into 96 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 54.0
Subtracting 96 from 96 leaves us with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 24

Going ahead to step 5:
7 divided by 24 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 540.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 24

Let's proceed to step 6:
24 can be fit into 72 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 5403.0
If we subtract 72 from 72, 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.

On to step 7:
The number 24 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5403.0
Subtracting 0 from 0 leaves us 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.

Going ahead to step 8:
The number 24 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5403.0
If we take 0 away from 0, 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.

The quotient of the division is 5403.0, and the remainder is 0.0.
