Let's divide 21549 by 23
We want to divide 21549 by 23.

Moving on to step 1:
23 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 23

Moving on to step 2:
23 can be fit into 21 0 times, resulting in a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 23

On to step 3:
215 divided by 23 is 9 with a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 207 from 215, we get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 23

Step 4:
When dividing 84 by 23, we get 3 with a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 93.0
Deduct 69 from 84 and we're left with 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 23

Going ahead to step 5:
The number 23 fits into 159 6 times, leaving a remainder of 21.
Use 6 as the next digit of our solution. 
Result so far: 936.0
If we take 138 away from 159, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 6:
23 goes into 210 9 times with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 936.9
Subtracting 207 from 210 leaves us 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 7:
When dividing 30 by 23, we get 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 936.91
If we take 23 away from 30, we end up 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.

On to step 8:
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: 936.913
Subtract 69 from 70 to 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.

Advancing to step 9:
23 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 936.913
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.

Step 10:
23 can be fit into 100 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 936.91304
Subtracting 92 from 100 leaves us with 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 11:
23 can be fit into 80 3 times, resulting in a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 936.913043
Subtracting 69 from 80 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 12:
23 goes into 110 4 times with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 936.9130434
Deduct 92 from 110 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 13:
23 can be fit into 180 7 times, resulting in a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 936.91304347
The remainder is 19 after subtracting 161 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Our division results in 936.91304347 with a remaining 1.9e-08.
