304594 ÷ 16 
The aim is to understand the frequency of 16 in 304594.

Step 1:
When dividing 3 by 16, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 16

On to step 2:
30 divided by 16 is 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 16 from 30 leaves us with 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 16

Let's proceed to step 3:
16 can be fit into 144 9 times, resulting in a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtracting 144 from 144 leaves us with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 16

Step 4:
16 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 190.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 16

Going ahead to step 5:
59 divided by 16 is 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 1903.0
Subtracting 48 from 59 leaves us with 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 16

Step 6:
If we divide 114 by 16, we get 7 and a remainder of 2.
The next digit of our result is 7. 
Result so far: 19037.0
Subtract 112 from 114 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
16 goes into 20 1 times with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 19037.1
Deduct 16 from 20 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
16 can be fit into 40 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 19037.12
Subtract 32 from 40 to 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 9:
16 can be fit into 80 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 19037.125
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.

Let's proceed to step 10:
16 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 19037.125
If we take 0 away from 0, we end up 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.

Going ahead to step 11:
16 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 19037.125
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 19037.125 and a remainder of 0.0.
