240099 ÷ 23 
We're looking to find how many times 23 goes into 240099.

Going ahead to step 1:
If we divide 2 by 23, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 23

Advancing to step 2:
23 goes into 24 1 times with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 23 from 24 leaves us with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 23

Step 3:
23 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 10, we end up with 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 23

On to step 4:
When dividing 100 by 23, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 104.0
Subtract 92 from 100 to get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 23

Going ahead to step 5:
The number 23 fits into 89 3 times, leaving a remainder of 20.
The next digit of our result is 3. 
Result so far: 1043.0
If we subtract 69 from 89, we get 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 23

Let's proceed to step 6:
The number 23 fits into 209 9 times, leaving a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 10439.0
Subtracting 207 from 209 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
23 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 10439.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
23 goes into 200 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 10439.08
Subtracting 184 from 200 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
23 can be fit into 160 6 times, resulting in a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 10439.086
The remainder is 22 after subtracting 138 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 10:
If we divide 220 by 23, we get 9 and a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 10439.0869
The remainder is 13 after subtracting 207 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 11:
23 goes into 130 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 10439.08695
Subtracting 115 from 130 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 12:
When dividing 150 by 23, we get 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 10439.086956
Subtract 138 from 150 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 13:
23 goes into 120 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 10439.0869565
Deduct 115 from 120 and we're left 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.

On to step 14:
23 goes into 50 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 10439.08695652
If we take 46 away from 50, we end up 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.

Our division results in 10439.08695652 with a remaining 4e-09.
