499560 divided by 23 
We want to divide 499560 by 23.

Step 1:
The number 23 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 23

Going ahead to step 2:
If we divide 49 by 23, we get 2 and a remainder of 3.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 46 from 49 leaves us with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 23

On to step 3:
When dividing 39 by 23, we get 1 with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we subtract 23 from 39, we get 16.
Grab the next digit (5) from the dividend, add it to 16, then carry on: 165 / 23

Let's proceed to step 4:
23 goes into 165 7 times with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 217.0
The remainder is 4 after subtracting 161 from 165.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 23

Let's proceed to step 5:
If we divide 46 by 23, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2172.0
Subtracting 46 from 46 leaves us with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 23

Going ahead to step 6:
23 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 21720.0
If we subtract 0 from 0, 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.

Moving on to step 7:
0 divided by 23 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 21720.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
23 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 21720.0
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 final result is 21720.0 with a remainder of 0.0.
