Let's divide 408660 by 42
We want to figure out the number of times 408660 can be divided by 42.

Let's proceed to step 1:
The number 42 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 42

Advancing to step 2:
40 divided by 42 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Take the next digit (8) from the dividend and append it to 40, then repeat: 408 / 42

Moving on to step 3:
42 goes into 408 9 times with a remainder of 30.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 378 from 408 to get 30.
Append the next digit (6) from the dividend to 30 and continue with: 306 / 42

Let's proceed to step 4:
42 goes into 306 7 times with a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 97.0
If we take 294 away from 306, we end up with 12.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 42

On to step 5:
The number 42 fits into 126 3 times, leaving a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 973.0
If we subtract 126 from 126, we get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 42

Going ahead to step 6:
The number 42 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 9730.0
Subtract 0 from 0 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.

Advancing to step 7:
When dividing 0 by 42, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9730.0
Subtract 0 from 0 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.

Advancing to step 8:
42 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9730.0
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.

In conclusion, the division gives 9730.0 with a balance of 0.0.
