808311 ÷ 12 
We want to figure out the number of times 808311 can be divided by 12.

Going ahead to step 1:
12 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 12

Moving on to step 2:
12 goes into 80 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 72 away from 80, we end up with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 12

Advancing to step 3:
When dividing 88 by 12, we get 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 67.0
Subtracting 84 from 88 leaves us with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 12

Let's proceed to step 4:
12 can be fit into 43 3 times, resulting in a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 673.0
The remainder is 7 after subtracting 36 from 43.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 12

Step 5:
12 can be fit into 71 5 times, resulting in a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 6735.0
Subtract 60 from 71 to get 11.
Append the next digit (1) from the dividend to 11 and continue with: 111 / 12

Let's proceed to step 6:
111 divided by 12 is 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 67359.0
The remainder is 3 after subtracting 108 from 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
12 can be fit into 30 2 times, resulting in a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 67359.2
Deduct 24 from 30 and we're left 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.

Moving on to step 8:
If we divide 60 by 12, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 67359.25
If we subtract 60 from 60, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 67359.25
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 67359.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 67359.25 with a remainder of 0.0.
