We look at the division of 300640 by 16 
The aim is to understand the frequency of 16 in 300640.

Let's proceed to step 1:
3 divided by 16 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 16

Moving on to step 2:
If we divide 30 by 16, we get 1 and a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 16 away from 30, we end up with 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 16

Step 3:
16 can be fit into 140 8 times, resulting in a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Deduct 128 from 140 and we're left with 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 16

Moving on to step 4:
16 goes into 126 7 times with a remainder of 14.
The next digit of our result is 7. 
Result so far: 187.0
Subtract 112 from 126 to get 14.
Bring next digit (4) of the dividend behind the 14 and repeat the process: 144 / 16

Moving on to step 5:
16 goes into 144 9 times with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 1879.0
If we subtract 144 from 144, we get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 16

On to step 6:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 18790.0
Subtract 0 from 0 to 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.

On to step 7:
When dividing 0 by 16, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 18790.0
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.

Advancing to step 8:
16 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 18790.0
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.

In conclusion, the division gives 18790.0 with a balance of 0.0.
