216636 ÷ 23 
Our goal is to divide 216636 by 23.

Step 1:
2 divided by 23 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 23

Step 2:
23 can be fit into 21 0 times, resulting in a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 23

On to step 3:
If we divide 216 by 23, we get 9 and a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 207 away from 216, we end up with 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 23

Moving on to step 4:
The number 23 fits into 96 4 times, leaving a remainder of 4.
The next digit of our result is 4. 
Result so far: 94.0
Subtract 92 from 96 to get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 23

Step 5:
When dividing 43 by 23, we get 1 with a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 941.0
If we subtract 23 from 43, we get 20.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 23

On to step 6:
When dividing 206 by 23, we get 8 with a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 9418.0
Subtract 184 from 206 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
The number 23 fits into 220 9 times, leaving a remainder of 13.
The next digit of our result is 9. 
Result so far: 9418.9
Deduct 207 from 220 and we're left with 13.
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 8:
23 can be fit into 130 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 9418.95
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.

On to step 9:
When dividing 150 by 23, we get 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 9418.956
Subtracting 138 from 150 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
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: 9418.9565
If we subtract 115 from 120, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 11:
23 goes into 50 2 times with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 9418.95652
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.

Step 12:
When dividing 40 by 23, we get 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 9418.956521
The remainder is 17 after subtracting 23 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 13:
If we divide 170 by 23, we get 7 and a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 9418.9565217
Subtracting 161 from 170 leaves us 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.

Let's proceed to step 14:
If we divide 90 by 23, we get 3 and a remainder of 21.
The next digit of our result is 3. 
Result so far: 9418.95652173
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.

Our division results in 9418.95652173 with a remaining 2.1e-08.
