We look at the division of 3840 by 1 
We want to figure out the number of times 3840 can be divided by 1.

Step 1:
1 can be fit into 3 3 times, resulting in a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 3 from 3, we get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 1

Going ahead to step 2:
1 goes into 8 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 38.0
Subtract 8 from 8 to get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

Let's proceed to step 3:
4 divided by 1 is 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 384.0
Subtracting 4 from 4 leaves us with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 1

Advancing to step 4:
1 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3840.0
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 5:
1 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3840.0
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.

Going ahead to step 6:
When dividing 0 by 1, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3840.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 3840.0 with a remaining 0.0.
