303497 divided by 16 
The aim is to understand the frequency of 16 in 303497.

Going ahead to step 1:
16 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 16

Let's proceed to step 2:
When dividing 30 by 16, we get 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 16 from 30 and we're left with 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 16

Moving on to step 3:
When dividing 143 by 16, we get 8 with a remainder of 15.
The next digit of our result is 8. 
Result so far: 18.0
The remainder is 15 after subtracting 128 from 143.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 16

Step 4:
The number 16 fits into 154 9 times, leaving a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 189.0
Subtracting 144 from 154 leaves us with 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 16

Moving on to step 5:
If we divide 109 by 16, we get 6 and a remainder of 13.
Record the quotient 6 as the next digit in the result. 
Result so far: 1896.0
If we subtract 96 from 109, we get 13.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 16

Moving on to step 6:
16 can be fit into 137 8 times, resulting in a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 18968.0
The remainder is 9 after subtracting 128 from 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
16 can be fit into 90 5 times, resulting in a remainder of 10.
The next digit of our result is 5. 
Result so far: 18968.5
Subtract 80 from 90 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
The number 16 fits into 100 6 times, leaving a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 18968.56
If we subtract 96 from 100, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
When dividing 40 by 16, we get 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 18968.562
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.

Step 10:
If we divide 80 by 16, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 18968.5625
If we take 80 away from 80, 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.

Advancing to step 11:
16 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 18968.5625
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.

On to step 12:
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: 18968.5625
Subtracting 0 from 0 leaves us 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.

The final outcome is 18968.5625, with a leftover of 0.0.
