499664 ÷ 23 
We want to figure out the number of times 499664 can be divided by 23.

Advancing to step 1:
4 divided by 23 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 23

Let's proceed to step 2:
The number 23 fits into 49 2 times, leaving a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 3 after subtracting 46 from 49.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 23

Going ahead to step 3:
The number 23 fits into 39 1 times, leaving a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we subtract 23 from 39, we get 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 23

Going ahead to step 4:
If we divide 166 by 23, we get 7 and a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 217.0
Subtract 161 from 166 to get 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 23

On to step 5:
23 goes into 56 2 times with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 2172.0
If we take 46 away from 56, we end up with 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 23

Going ahead to step 6:
23 goes into 104 4 times with a remainder of 12.
The next digit of our result is 4. 
Result so far: 21724.0
The remainder is 12 after subtracting 92 from 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
If we divide 120 by 23, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 21724.5
Subtracting 115 from 120 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
23 can be fit into 50 2 times, resulting in a remainder of 4.
The next digit of our result is 2. 
Result so far: 21724.52
Subtracting 46 from 50 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
40 divided by 23 is 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 21724.521
Deduct 23 from 40 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 10:
If we divide 170 by 23, we get 7 and a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 21724.5217
If we subtract 161 from 170, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 11:
23 goes into 90 3 times with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 21724.52173
If we subtract 69 from 90, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 12:
23 can be fit into 210 9 times, resulting in a remainder of 3.
The next digit of our result is 9. 
Result so far: 21724.521739
If we subtract 207 from 210, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 13:
23 goes into 30 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 21724.5217391
Subtracting 23 from 30 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 14:
The number 23 fits into 70 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 21724.52173913
If we take 69 away from 70, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 21724.52173913 and a remainder of 1e-09.
