12309 ÷ 65 
We want to figure out the number of times 12309 can be divided by 65.

Step 1:
The number 65 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 65

On to step 2:
12 divided by 65 is 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 65

Going ahead to step 3:
The number 65 fits into 123 1 times, leaving a remainder of 58.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 65 away from 123, we end up with 58.
Bring next digit (0) of the dividend behind the 58 and repeat the process: 580 / 65

Moving on to step 4:
65 can be fit into 580 8 times, resulting in a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 18.0
The remainder is 60 after subtracting 520 from 580.
Include the next digit (9) from the dividend after 60, then repeat: 609 / 65

Step 5:
65 can be fit into 609 9 times, resulting in a remainder of 24.
Write down 9 as next digit of the result. 
Result so far: 189.0
Deduct 585 from 609 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 6:
240 divided by 65 is 3 with a remainder of 45.
Record the quotient 3 as the next digit in the result. 
Result so far: 189.3
If we take 195 away from 240, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 7:
65 goes into 450 6 times with a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 189.36
The remainder is 60 after subtracting 390 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
The number 65 fits into 600 9 times, leaving a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 189.369
Deduct 585 from 600 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.

Moving on to step 9:
150 divided by 65 is 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 189.3692
Subtract 130 from 150 to get 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 10:
The number 65 fits into 200 3 times, leaving a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 189.36923
Deduct 195 from 200 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 11:
50 divided by 65 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 189.36923
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 12:
65 can be fit into 500 7 times, resulting in a remainder of 45.
The number 7 becomes the next digit in our result. 
Result so far: 189.3692307
The remainder is 45 after subtracting 455 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 13:
When dividing 450 by 65, we get 6 with a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 189.36923076
Subtracting 390 from 450 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 189.36923076 with a remainder of 6e-08.
