840708 ÷ 12 
We're looking to find how many times 12 goes into 840708.

Moving on to step 1:
12 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 12

Moving on to step 2:
84 divided by 12 is 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 84 from 84 and we're left with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 12

On to step 3:
0 divided by 12 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
Subtracting 0 from 0 leaves us with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 12

Moving on to step 4:
If we divide 7 by 12, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 700.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 12

Going ahead to step 5:
70 divided by 12 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 7005.0
Subtracting 60 from 70 leaves us with 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 12

Advancing to step 6:
12 goes into 108 9 times with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 70059.0
If we subtract 108 from 108, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 70059.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
The number 12 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 70059.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 70059.0 with a remaining 0.0.
