We're dividing 499716 by 21 
We want to divide 499716 by 21.

Let's proceed to step 1:
21 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 21

Let's proceed to step 2:
21 goes into 49 2 times with a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 42 from 49, we get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 21

Let's proceed to step 3:
79 divided by 21 is 3 with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
If we take 63 away from 79, we end up with 16.
Append the next digit (7) from the dividend to 16 and continue with: 167 / 21

Step 4:
21 can be fit into 167 7 times, resulting in a remainder of 20.
The next digit of our result is 7. 
Result so far: 237.0
The remainder is 20 after subtracting 147 from 167.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 21

Let's proceed to step 5:
21 goes into 201 9 times with a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 2379.0
The remainder is 12 after subtracting 189 from 201.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 21

Going ahead to step 6:
When dividing 126 by 21, we get 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 23796.0
Subtract 126 from 126 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.

Let's proceed to step 7:
When dividing 0 by 21, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 23796.0
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.

Moving on to step 8:
0 divided by 21 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 23796.0
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 23796.0 with a remaining 0.0.
