We look at the division of 878684 by 6 
Let's see how many times 6 fits into 878684.

On to step 1:
The number 6 fits into 8 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 2 after subtracting 6 from 8.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 6

Advancing to step 2:
6 goes into 27 4 times with a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 24 from 27 and we're left with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 6

Advancing to step 3:
6 goes into 38 6 times with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 146.0
Subtract 36 from 38 to get 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 6

Going ahead to step 4:
26 divided by 6 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 1464.0
The remainder is 2 after subtracting 24 from 26.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 6

Let's proceed to step 5:
6 can be fit into 28 4 times, resulting in a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 14644.0
If we take 24 away from 28, we end up with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 6

Advancing to step 6:
6 goes into 44 7 times with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 146447.0
Subtract 42 from 44 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
The number 6 fits into 20 3 times, leaving a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 146447.3
If we take 18 away from 20, we end up 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.

Step 8:
6 can be fit into 20 3 times, resulting in a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 146447.33
Deduct 18 from 20 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.

The final result is 146447.33 with a remainder of 0.002.
