We divide 801409 by 12
Let's see how many times 12 fits into 801409.

On to step 1:
If we divide 8 by 12, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 12

Step 2:
If we divide 80 by 12, we get 6 and a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 72 away from 80, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 12

Advancing to step 3:
The number 12 fits into 81 6 times, leaving a remainder of 9.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
The remainder is 9 after subtracting 72 from 81.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 12

Advancing to step 4:
12 goes into 94 7 times with a remainder of 10.
The next digit of our result is 7. 
Result so far: 667.0
If we subtract 84 from 94, we get 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 12

Let's proceed to step 5:
12 can be fit into 100 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 6678.0
If we subtract 96 from 100, we get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 12

Moving on to step 6:
12 goes into 49 4 times with a remainder of 1.
The next digit of our result is 4. 
Result so far: 66784.0
The remainder is 1 after subtracting 48 from 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
If we divide 10 by 12, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 66784.0
Subtracting 0 from 10 leaves us 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.

On to step 8:
The number 12 fits into 100 8 times, leaving a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 66784.08
If we take 96 away from 100, 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.

Going ahead to step 9:
If we divide 40 by 12, we get 3 and a remainder of 4.
The next digit of our result is 3. 
Result so far: 66784.083
Subtracting 36 from 40 leaves us 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.

Step 10:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 66784.0833
Subtract 36 from 40 to 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.

After the division, we end up with 66784.0833 and a remainder of 4e-05.
