Let's divide 803321 by 12
Let's see how many times 12 fits into 803321.

On to step 1:
If we divide 8 by 12, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 12

Going ahead to step 2:
If we divide 80 by 12, we get 6 and a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 72 from 80 to get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 12

Let's proceed to step 3:
12 can be fit into 83 6 times, resulting in a remainder of 11.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
If we take 72 away from 83, we end up with 11.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 12

Moving on to step 4:
12 can be fit into 113 9 times, resulting in a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 669.0
If we subtract 108 from 113, we get 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 12

Moving on to step 5:
The number 12 fits into 52 4 times, leaving a remainder of 4.
The next digit of our result is 4. 
Result so far: 6694.0
If we take 48 away from 52, we end up with 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 12

On to step 6:
12 can be fit into 41 3 times, resulting in a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 66943.0
Deduct 36 from 41 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.

Step 7:
50 divided by 12 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 66943.4
Deduct 48 from 50 and we're left 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.

Going ahead to step 8:
If we divide 20 by 12, we get 1 and a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 66943.41
If we subtract 12 from 20, 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.

Let's proceed to step 9:
12 goes into 80 6 times with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 66943.416
Subtracting 72 from 80 leaves us 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.

Let's proceed to step 10:
The number 12 fits into 80 6 times, leaving a remainder of 8.
The next digit of our result is 6. 
Result so far: 66943.4166
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 66943.4166, and the remainder is 8e-05.
