Let's divide 516821 by 24
Our goal is to divide 516821 by 24.

Let's proceed to step 1:
The number 24 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 24

Step 2:
When dividing 51 by 24, we get 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 48 from 51, we get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 24

On to step 3:
If we divide 36 by 24, we get 1 and a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we take 24 away from 36, we end up with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 24

Moving on to step 4:
24 can be fit into 128 5 times, resulting in a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 215.0
If we subtract 120 from 128, we get 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 24

On to step 5:
If we divide 82 by 24, we get 3 and a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 2153.0
Deduct 72 from 82 and we're left with 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 24

Moving on to step 6:
If we divide 101 by 24, we get 4 and a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 21534.0
Subtract 96 from 101 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
When dividing 50 by 24, we get 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 21534.2
The remainder is 2 after subtracting 48 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
20 divided by 24 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 21534.2
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
If we divide 200 by 24, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 21534.208
Subtracting 192 from 200 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
24 can be fit into 80 3 times, resulting in a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 21534.2083
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
The number 24 fits into 80 3 times, leaving a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 21534.20833
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 21534.20833 with a remainder of 8e-06.
