We're dividing 21324 by 23 
We want to figure out the number of times 21324 can be divided by 23.

On to step 1:
23 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 23

Moving on to step 2:
The number 23 fits into 21 0 times, leaving a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 23

Let's proceed to step 3:
If we divide 213 by 23, we get 9 and a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 207 from 213 and we're left with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 23

Moving on to step 4:
62 divided by 23 is 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 92.0
Subtracting 46 from 62 leaves us with 16.
Bring next digit (4) of the dividend behind the 16 and repeat the process: 164 / 23

Advancing to step 5:
23 can be fit into 164 7 times, resulting in a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 927.0
If we subtract 161 from 164, 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 6:
The number 23 fits into 30 1 times, leaving a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 927.1
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.

Moving on to step 7:
23 can be fit into 70 3 times, resulting in a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 927.13
Subtracting 69 from 70 leaves us 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.

Step 8:
23 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 927.13
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
When dividing 100 by 23, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 927.1304
Subtract 92 from 100 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
When dividing 80 by 23, we get 3 with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 927.13043
The remainder is 11 after subtracting 69 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 11:
23 can be fit into 110 4 times, resulting in a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 927.130434
If we subtract 92 from 110, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 12:
When dividing 180 by 23, we get 7 with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 927.1304347
If we take 161 away from 180, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 13:
The number 23 fits into 190 8 times, leaving a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 927.13043478
If we subtract 184 from 190, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 927.13043478, with a leftover of 6e-09.
