We look at the division of 855166 by 6 
We want to figure out the number of times 855166 can be divided by 6.

On to step 1:
6 can be fit into 8 1 times, resulting in a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 6 from 8 leaves us with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 6

Going ahead to step 2:
If we divide 25 by 6, we get 4 and a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 14.0
Deduct 24 from 25 and we're left with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 6

Going ahead to step 3:
When dividing 15 by 6, we get 2 with a remainder of 3.
The next digit of our result is 2. 
Result so far: 142.0
Deduct 12 from 15 and we're left with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 6

On to step 4:
The number 6 fits into 31 5 times, leaving a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 1425.0
The remainder is 1 after subtracting 30 from 31.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 6

Going ahead to step 5:
16 divided by 6 is 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 14252.0
If we take 12 away from 16, we end up with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 6

Advancing to step 6:
If we divide 46 by 6, we get 7 and a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 142527.0
Subtract 42 from 46 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.

Step 7:
The number 6 fits into 40 6 times, leaving a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 142527.6
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.

Moving on to step 8:
40 divided by 6 is 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 142527.66
The remainder is 4 after subtracting 36 from 40.
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 142527.66 with a remaining 0.004.
