20688 ÷ 23 
We want to divide 20688 by 23.

Advancing to step 1:
If we divide 2 by 23, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 23

Going ahead to step 2:
23 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Bring next digit (6) of the dividend behind the 20 and repeat the process: 206 / 23

Going ahead to step 3:
206 divided by 23 is 8 with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 184 away from 206, we end up with 22.
Include the next digit (8) from the dividend after 22, then repeat: 228 / 23

Advancing to step 4:
23 can be fit into 228 9 times, resulting in a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
If we subtract 207 from 228, we get 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 23

Let's proceed to step 5:
If we divide 218 by 23, we get 9 and a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 899.0
The remainder is 11 after subtracting 207 from 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 6:
23 can be fit into 110 4 times, resulting in a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 899.4
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.

Advancing to step 7:
The number 23 fits into 180 7 times, leaving a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 899.47
Deduct 161 from 180 and we're left 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 8:
190 divided by 23 is 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 899.478
Subtracting 184 from 190 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
The number 23 fits into 60 2 times, leaving a remainder of 14.
The next digit of our result is 2. 
Result so far: 899.4782
Subtract 46 from 60 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
If we divide 140 by 23, we get 6 and a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 899.47826
Subtract 138 from 140 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
23 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 899.47826
Deduct 0 from 20 and we're left with 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 12:
200 divided by 23 is 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 899.4782608
The remainder is 16 after subtracting 184 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
160 divided by 23 is 6 with a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 899.47826086
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.

Our division results in 899.47826086 with a remaining 2.2e-08.
