We look at the division of 406891 by 6 
Let's see how many times 6 fits into 406891.

Let's proceed to step 1:
6 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 6

Let's proceed to step 2:
When dividing 40 by 6, we get 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 36 from 40 leaves us with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 6

Going ahead to step 3:
6 can be fit into 46 7 times, resulting in a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 67.0
Deduct 42 from 46 and we're left with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 6

Step 4:
6 can be fit into 48 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 678.0
If we take 48 away from 48, we end up with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 6

Step 5:
The number 6 fits into 9 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 6781.0
Subtract 6 from 9 to get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 6

Step 6:
6 can be fit into 31 5 times, resulting in a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 67815.0
The remainder is 1 after subtracting 30 from 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
The number 6 fits into 10 1 times, leaving a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 67815.1
Subtract 6 from 10 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.

Advancing to step 8:
6 goes into 40 6 times with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 67815.16
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.

Step 9:
When dividing 40 by 6, we get 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 67815.166
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.

After the division, we end up with 67815.166 and a remainder of 0.0004.
