We look at the division of 398684 by 6 
Our goal is to divide 398684 by 6.

Advancing to step 1:
6 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 6

Let's proceed to step 2:
The number 6 fits into 39 6 times, leaving a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 36 away from 39, we end up with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 6

Step 3:
The number 6 fits into 38 6 times, leaving a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 66.0
Deduct 36 from 38 and we're left with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 6

Moving on to step 4:
When dividing 26 by 6, we get 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 664.0
Subtract 24 from 26 to get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 6

Let's proceed to step 5:
28 divided by 6 is 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 6644.0
Deduct 24 from 28 and we're left with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 6

Advancing to step 6:
6 can be fit into 44 7 times, resulting in a remainder of 2.
The next digit of our result is 7. 
Result so far: 66447.0
Subtracting 42 from 44 leaves us 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.

Advancing to step 7:
When dividing 20 by 6, we get 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 66447.3
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.

Let's proceed to step 8:
6 goes into 20 3 times with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 66447.33
Subtract 18 from 20 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.

The final result is 66447.33 with a remainder of 0.002.
