We divide 393660 by 10
We want to divide 393660 by 10.

Moving on to step 1:
3 divided by 10 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 10

Step 2:
If we divide 39 by 10, we get 3 and a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 30 from 39 leaves us with 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 10

Advancing to step 3:
93 divided by 10 is 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 39.0
The remainder is 3 after subtracting 90 from 93.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 10

Going ahead to step 4:
10 can be fit into 36 3 times, resulting in a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 393.0
If we subtract 30 from 36, we get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 10

Advancing to step 5:
The number 10 fits into 66 6 times, leaving a remainder of 6.
The next digit of our result is 6. 
Result so far: 3936.0
If we subtract 60 from 66, we get 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 10

Moving on to step 6:
10 can be fit into 60 6 times, resulting in a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 39366.0
Subtract 60 from 60 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
0 divided by 10 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 39366.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
If we divide 0 by 10, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 39366.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 39366.0 with a balance of 0.0.
