809237 ÷ 12 
We're looking to find how many times 12 goes into 809237.

Advancing to step 1:
12 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 12

Step 2:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 72 from 80, we get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 12

Let's proceed to step 3:
89 divided by 12 is 7 with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 67.0
Subtracting 84 from 89 leaves us with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 12

Step 4:
52 divided by 12 is 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 674.0
If we subtract 48 from 52, we get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 12

Let's proceed to step 5:
12 can be fit into 43 3 times, resulting in a remainder of 7.
The next digit of our result is 3. 
Result so far: 6743.0
The remainder is 7 after subtracting 36 from 43.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 12

On to step 6:
The number 12 fits into 77 6 times, leaving a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 67436.0
If we subtract 72 from 77, 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.

Step 7:
50 divided by 12 is 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 67436.4
Subtracting 48 from 50 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.

Let's proceed to step 8:
20 divided by 12 is 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 67436.41
Deduct 12 from 20 and we're left 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.

On to step 9:
12 goes into 80 6 times with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 67436.416
Deduct 72 from 80 and we're left 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.

Going ahead to step 10:
If we divide 80 by 12, we get 6 and a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 67436.4166
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 67436.4166 with a balance of 8e-05.
