We look at the division of 393910 by 6 
Our goal is to divide 393910 by 6.

Advancing to step 1:
When dividing 3 by 6, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 6

Going ahead to step 2:
When dividing 39 by 6, we get 6 with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 36 from 39, we get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 6

Step 3:
When dividing 33 by 6, we get 5 with a remainder of 3.
The next digit of our result is 5. 
Result so far: 65.0
Subtract 30 from 33 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 6

Advancing to step 4:
6 goes into 39 6 times with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 656.0
Subtract 36 from 39 to get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 6

Step 5:
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: 6565.0
Subtracting 30 from 31 leaves us with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 6

Step 6:
If we divide 10 by 6, we get 1 and a remainder of 4.
The next digit of our result is 1. 
Result so far: 65651.0
If we take 6 away from 10, 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:
40 divided by 6 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 65651.6
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:
If we divide 40 by 6, we get 6 and a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 65651.66
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.

The final result is 65651.66 with a remainder of 0.004.
