We look at the division of 810840 by 24 
Our goal is to divide 810840 by 24.

Let's proceed to step 1:
24 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 24

Step 2:
81 divided by 24 is 3 with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 72 from 81, we get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 24

Moving on to step 3:
24 can be fit into 90 3 times, resulting in a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
The remainder is 18 after subtracting 72 from 90.
Append the next digit (8) from the dividend to 18 and continue with: 188 / 24

Step 4:
When dividing 188 by 24, we get 7 with a remainder of 20.
The next digit of our result is 7. 
Result so far: 337.0
The remainder is 20 after subtracting 168 from 188.
Bring next digit (4) of the dividend behind the 20 and repeat the process: 204 / 24

Advancing to step 5:
204 divided by 24 is 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 3378.0
Subtracting 192 from 204 leaves us with 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 24

Moving on to step 6:
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: 33785.0
Subtract 120 from 120 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.

Going ahead to step 7:
When dividing 0 by 24, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 33785.0
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.

Advancing to step 8:
24 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 33785.0
Deduct 0 from 0 and we're left 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 33785.0, and the remainder is 0.0.
