Let's divide 54305 by 15
We want to figure out the number of times 54305 can be divided by 15.

Step 1:
15 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 15

On to step 2:
15 can be fit into 54 3 times, resulting in a remainder of 9.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 45 from 54, we get 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 15

Moving on to step 3:
The number 15 fits into 93 6 times, leaving a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 36.0
If we take 90 away from 93, we end up with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 15

On to step 4:
30 divided by 15 is 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 362.0
The remainder is 0 after subtracting 30 from 30.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 15

Step 5:
The number 15 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 3620.0
The remainder is 5 after subtracting 0 from 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 6:
If we divide 50 by 15, we get 3 and a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 3620.3
The remainder is 5 after subtracting 45 from 50.
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 7:
15 goes into 50 3 times with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 3620.33
Subtracting 45 from 50 leaves us 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 3620.33 with a remainder of 0.005.
