72907 ÷ 16 
The aim is to understand the frequency of 16 in 72907.

Step 1:
If we divide 7 by 16, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 16

Going ahead to step 2:
72 divided by 16 is 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 64 from 72 to get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 16

Step 3:
If we divide 89 by 16, we get 5 and a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
Subtract 80 from 89 to get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 16

Step 4:
16 can be fit into 90 5 times, resulting in a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 455.0
Subtracting 80 from 90 leaves us with 10.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 16

Moving on to step 5:
If we divide 107 by 16, we get 6 and a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 4556.0
Subtracting 96 from 107 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 6:
16 can be fit into 110 6 times, resulting in a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 4556.6
Subtracting 96 from 110 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
The number 16 fits into 140 8 times, leaving a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 4556.68
Subtracting 128 from 140 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
When dividing 120 by 16, we get 7 with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 4556.687
Subtract 112 from 120 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 9:
When dividing 80 by 16, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 4556.6875
If we subtract 80 from 80, 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.

Let's proceed to step 10:
0 divided by 16 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4556.6875
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 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4556.6875
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 result is 4556.6875 with a remainder of 0.0.
