841300 divided by 12 
We're looking to find how many times 12 goes into 841300.

Step 1:
12 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 12

Going ahead to step 2:
84 divided by 12 is 7 with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 84 from 84 to get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 12

Let's proceed to step 3:
12 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
Subtract 0 from 1 to get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 12

On to step 4:
The number 12 fits into 13 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 701.0
Subtract 12 from 13 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 12

Going ahead to step 5:
When dividing 10 by 12, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 7010.0
The remainder is 10 after subtracting 0 from 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 12

Step 6:
The number 12 fits into 100 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 70108.0
If we subtract 96 from 100, 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.

On to step 7:
When dividing 40 by 12, we get 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 70108.3
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.

Moving on to step 8:
12 goes into 40 3 times with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 70108.33
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.

After the division, we end up with 70108.33 and a remainder of 0.004.
