546308 ÷ 15 
We're looking to find how many times 15 goes into 546308.

Going ahead to step 1:
15 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 15

Let's proceed to step 2:
15 goes into 54 3 times with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 45 away from 54, we end up with 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 15

Step 3:
If we divide 96 by 15, we get 6 and a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
If we take 90 away from 96, we end up with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 15

Step 4:
63 divided by 15 is 4 with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 364.0
Subtracting 60 from 63 leaves us with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 15

Moving on to step 5:
15 goes into 30 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 3642.0
If we subtract 30 from 30, we get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 15

Going ahead to step 6:
15 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 36420.0
If we subtract 0 from 8, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
The number 15 fits into 80 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 36420.5
If we take 75 away from 80, we end up 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.

Advancing to step 8:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 36420.53
If we take 45 away from 50, we end up 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.

Moving on to step 9:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 36420.533
If we subtract 45 from 50, 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.

After the division, we end up with 36420.533 and a remainder of 0.0005.
