813931 divided by 6 
Let's see how many times 6 fits into 813931.

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
Deduct 6 from 8 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 6

Advancing to step 2:
6 can be fit into 21 3 times, resulting in a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 13.0
The remainder is 3 after subtracting 18 from 21.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 6

Step 3:
6 can be fit into 33 5 times, resulting in a remainder of 3.
The next digit of our result is 5. 
Result so far: 135.0
If we subtract 30 from 33, we get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 6

Moving on to step 4:
If we divide 39 by 6, we get 6 and a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 1356.0
Deduct 36 from 39 and we're left with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 6

Going ahead to step 5:
If we divide 33 by 6, we get 5 and a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 13565.0
Deduct 30 from 33 and we're left with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 6

Step 6:
6 goes into 31 5 times with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 135655.0
Subtracting 30 from 31 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
10 divided by 6 is 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 135655.1
Deduct 6 from 10 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.

Going ahead to step 8:
40 divided by 6 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 135655.16
Subtract 36 from 40 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.

Let's proceed to step 9:
When dividing 40 by 6, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 135655.166
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.

The final result is 135655.166 with a remainder of 0.0004.
