Let's divide 379904 by 15
We want to figure out the number of times 379904 can be divided by 15.

Going ahead to step 1:
If we divide 3 by 15, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 15

Moving on to step 2:
The number 15 fits into 37 2 times, leaving a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 30 away from 37, we end up with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 15

Moving on to step 3:
When dividing 79 by 15, we get 5 with a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we take 75 away from 79, we end up with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 15

Step 4:
49 divided by 15 is 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 253.0
Subtracting 45 from 49 leaves us with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 15

On to step 5:
15 can be fit into 40 2 times, resulting in a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 2532.0
Subtracting 30 from 40 leaves us with 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 15

On to step 6:
When dividing 104 by 15, we get 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 25326.0
If we subtract 90 from 104, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
15 can be fit into 140 9 times, resulting in a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 25326.9
If we subtract 135 from 140, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
If we divide 50 by 15, we get 3 and a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 25326.93
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
50 divided by 15 is 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 25326.933
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 25326.933 with a remainder of 0.0005.
