678520 ÷ 24 
Our goal is to divide 678520 by 24.

Step 1:
When dividing 6 by 24, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 24

On to step 2:
When dividing 67 by 24, we get 2 with a remainder of 19.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 48 away from 67, we end up with 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 24

Going ahead to step 3:
198 divided by 24 is 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 28.0
If we take 192 away from 198, we end up with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 24

Advancing to step 4:
If we divide 65 by 24, we get 2 and a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 282.0
If we subtract 48 from 65, we get 17.
Append the next digit (2) from the dividend to 17 and continue with: 172 / 24

Advancing to step 5:
When dividing 172 by 24, we get 7 with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 2827.0
The remainder is 4 after subtracting 168 from 172.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 24

Let's proceed to step 6:
If we divide 40 by 24, we get 1 and a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 28271.0
If we subtract 24 from 40, we get 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 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: 28271.6
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.

Step 8:
24 can be fit into 160 6 times, resulting in a remainder of 16.
The next digit of our result is 6. 
Result so far: 28271.66
Deduct 144 from 160 and we're left 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 outcome is 28271.66, with a leftover of 0.016.
