808854 ÷ 12 
We want to divide 808854 by 12.

Step 1:
8 divided by 12 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 12

Step 2:
80 divided by 12 is 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 72 from 80, we get 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 12

Moving on to step 3:
12 can be fit into 88 7 times, resulting in a remainder of 4.
The next digit of our result is 7. 
Result so far: 67.0
Subtracting 84 from 88 leaves us with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 12

Advancing to step 4:
When dividing 48 by 12, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 674.0
The remainder is 0 after subtracting 48 from 48.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 12

Advancing to step 5:
If we divide 5 by 12, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 6740.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 12

Step 6:
54 divided by 12 is 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 67404.0
Subtracting 48 from 54 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.

On to step 7:
12 can be fit into 60 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 67404.5
Deduct 60 from 60 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.

Let's proceed to step 8:
12 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 67404.5
Subtracting 0 from 0 leaves us 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.

Let's proceed to step 9:
When dividing 0 by 12, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 67404.5
Subtracting 0 from 0 leaves us 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.

After the division, we end up with 67404.5 and a remainder of 0.0.
