266009 ÷ 23 
We want to figure out the number of times 266009 can be divided by 23.

On to step 1:
When dividing 2 by 23, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 23

Moving on to step 2:
If we divide 26 by 23, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 23 from 26, we get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 23

Going ahead to step 3:
The number 23 fits into 36 1 times, leaving a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 13 after subtracting 23 from 36.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 23

Going ahead to step 4:
When dividing 130 by 23, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 115.0
Deduct 115 from 130 and we're left with 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 23

Step 5:
If we divide 150 by 23, we get 6 and a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 1156.0
If we take 138 away from 150, we end up with 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 23

Step 6:
23 goes into 129 5 times with a remainder of 14.
The next digit of our result is 5. 
Result so far: 11565.0
If we take 115 away from 129, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
23 can be fit into 140 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 11565.6
Subtracting 138 from 140 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
23 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 11565.6
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
The number 23 fits into 200 8 times, leaving a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 11565.608
Subtract 184 from 200 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
If we divide 160 by 23, we get 6 and a remainder of 22.
The next digit of our result is 6. 
Result so far: 11565.6086
Subtracting 138 from 160 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 11:
When dividing 220 by 23, we get 9 with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 11565.60869
If we subtract 207 from 220, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 12:
23 goes into 130 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 11565.608695
Deduct 115 from 130 and we're left 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.

Step 13:
When dividing 150 by 23, we get 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 11565.6086956
If we take 138 away from 150, we end up 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 14:
23 goes into 120 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 11565.60869565
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.

The final outcome is 11565.60869565, with a leftover of 5e-09.
