243920 divided by 23 
Let's see how many times 23 fits into 243920.

Going ahead to step 1:
23 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 23

Going ahead to step 2:
23 goes into 24 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 23 from 24 leaves us with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 23

Going ahead to step 3:
23 can be fit into 13 0 times, resulting in a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 13 and we're left with 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 23

Let's proceed to step 4:
The number 23 fits into 139 6 times, leaving a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 106.0
If we subtract 138 from 139, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 23

Advancing to step 5:
23 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 1060.0
The remainder is 12 after subtracting 0 from 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 23

On to step 6:
23 can be fit into 120 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 10605.0
The remainder is 5 after subtracting 115 from 120.
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 7:
The number 23 fits into 50 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 10605.2
Deduct 46 from 50 and we're left 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.

Let's proceed to step 8:
When dividing 40 by 23, we get 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 10605.21
If we take 23 away from 40, we end up 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.

On to step 9:
23 goes into 170 7 times with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 10605.217
If we take 161 away from 170, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 10:
23 can be fit into 90 3 times, resulting in a remainder of 21.
The next digit of our result is 3. 
Result so far: 10605.2173
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.

On to step 11:
210 divided by 23 is 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 10605.21739
If we take 207 away from 210, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 12:
23 can be fit into 30 1 times, resulting in a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 10605.217391
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.

Step 13:
23 goes into 70 3 times with a remainder of 1.
The next digit of our result is 3. 
Result so far: 10605.2173913
If we subtract 69 from 70, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 14:
23 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 10605.2173913
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 10605.2173913 with a remainder of 1e-08.
