Let's divide 408776 by 16
The aim is to understand the frequency of 16 in 408776.

Step 1:
16 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 16

On to step 2:
When dividing 40 by 16, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 32 from 40 to get 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 16

Advancing to step 3:
When dividing 88 by 16, we get 5 with a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we subtract 80 from 88, we get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 16

Advancing to step 4:
16 goes into 87 5 times with a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 255.0
Subtract 80 from 87 to get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 16

Advancing to step 5:
When dividing 77 by 16, we get 4 with a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 2554.0
If we subtract 64 from 77, we get 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 16

Advancing to step 6:
When dividing 136 by 16, we get 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 25548.0
Subtracting 128 from 136 leaves us with 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 7:
If we divide 80 by 16, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 25548.5
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.

Moving on to step 8:
0 divided by 16 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 25548.5
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.

On to step 9:
0 divided by 16 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 25548.5
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.

The final result is 25548.5 with a remainder of 0.0.
