Let's divide 857986 by 6
Let's see how many times 6 fits into 857986.

Advancing to step 1:
8 divided by 6 is 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 2 after subtracting 6 from 8.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 6

Advancing to step 2:
6 goes into 25 4 times with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtract 24 from 25 to get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 6

Step 3:
When dividing 17 by 6, we get 2 with a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 142.0
If we take 12 away from 17, we end up with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 6

Moving on to step 4:
6 goes into 59 9 times with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 1429.0
If we take 54 away from 59, we end up with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 6

Step 5:
6 can be fit into 58 9 times, resulting in a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 14299.0
Subtracting 54 from 58 leaves us with 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 6

Step 6:
If we divide 46 by 6, we get 7 and a remainder of 4.
The next digit of our result is 7. 
Result so far: 142997.0
If we take 42 away from 46, 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.

Advancing to step 7:
If we divide 40 by 6, we get 6 and a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 142997.6
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.

Step 8:
The number 6 fits into 40 6 times, leaving a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 142997.66
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 142997.66 with a remaining 0.004.
