We look at the division of 393648 by 96 
We're looking to find how many times 96 goes into 393648.

Advancing to step 1:
The number 96 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 96

Step 2:
When dividing 39 by 96, we get 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 96

On to step 3:
96 can be fit into 393 4 times, resulting in a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 384 from 393, we get 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 96

Let's proceed to step 4:
When dividing 96 by 96, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 41.0
The remainder is 0 after subtracting 96 from 96.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 96

On to step 5:
When dividing 4 by 96, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 410.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 96

Advancing to step 6:
48 divided by 96 is 0 with a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 4100.0
If we subtract 0 from 48, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 7:
96 goes into 480 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 4100.5
If we subtract 480 from 480, we 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.

On to step 8:
96 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 4100.5
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.

Moving on to step 9:
The number 96 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4100.5
If we subtract 0 from 0, we 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.

The final outcome is 4100.5, with a leftover of 0.0.
