804274 ÷ 12 
We're looking to find how many times 12 goes into 804274.

On 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
If we take 0 away from 8, we end up with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 12

Advancing to step 2:
If we divide 80 by 12, we get 6 and a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 72 from 80 to get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 12

Let's proceed to step 3:
12 can be fit into 84 7 times, resulting in a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 67.0
If we subtract 84 from 84, we get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 12

Going ahead to step 4:
12 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 670.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 12

Let's proceed to step 5:
27 divided by 12 is 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 6702.0
Subtracting 24 from 27 leaves us with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 12

Going ahead to step 6:
12 goes into 34 2 times with a remainder of 10.
The next digit of our result is 2. 
Result so far: 67022.0
Deduct 24 from 34 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
If we divide 100 by 12, we get 8 and a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 67022.8
The remainder is 4 after subtracting 96 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 67022.83
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
If we divide 40 by 12, we get 3 and a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 67022.833
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 67022.833, and the remainder is 0.0004.
