We're dividing 844042 by 12 
Let's see how many times 12 fits into 844042.

Step 1:
12 goes into 8 0 times 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 (4) from the dividend to 8 and continue with: 84 / 12

Going ahead to step 2:
The number 12 fits into 84 7 times, leaving a remainder of 0.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 84 from 84 to get 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 12

Going ahead to step 3:
If we divide 4 by 12, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 70.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 12

Moving on to step 4:
The number 12 fits into 40 3 times, leaving a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 703.0
Subtract 36 from 40 to get 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 12

Going ahead to step 5:
When dividing 44 by 12, we get 3 with a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 7033.0
Deduct 36 from 44 and we're left with 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 12

Step 6:
The number 12 fits into 82 6 times, leaving a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 70336.0
If we subtract 72 from 82, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
When dividing 100 by 12, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 70336.8
Subtracting 96 from 100 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.

On to step 8:
12 goes into 40 3 times with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 70336.83
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.

Moving on to step 9:
12 goes into 40 3 times with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 70336.833
Deduct 36 from 40 and we're left 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.

Our division results in 70336.833 with a remaining 0.0004.
