315304 ÷ 16 
We're looking to find how many times 16 goes into 315304.

Advancing to step 1:
16 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 16

On to step 2:
16 goes into 31 1 times with a remainder of 15.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 16 from 31 leaves us with 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 16

On to step 3:
155 divided by 16 is 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Deduct 144 from 155 and we're left with 11.
Bring next digit (3) of the dividend behind the 11 and repeat the process: 113 / 16

Going ahead to step 4:
16 can be fit into 113 7 times, resulting in a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 197.0
Subtracting 112 from 113 leaves us with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 16

Moving on to step 5:
The number 16 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1970.0
The remainder is 10 after subtracting 0 from 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 16

On to step 6:
104 divided by 16 is 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 19706.0
If we subtract 96 from 104, 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.

Let's proceed to step 7:
If we divide 80 by 16, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 19706.5
The remainder is 0 after subtracting 80 from 80.
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 8:
0 divided by 16 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 19706.5
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.

Step 9:
16 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 19706.5
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 19706.5, with a leftover of 0.0.
