We look at the division of 856959 by 16 
The aim is to understand the frequency of 16 in 856959.

Going ahead to step 1:
16 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 16

Step 2:
When dividing 85 by 16, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 80 from 85 leaves us with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 16

On to step 3:
16 goes into 56 3 times with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 53.0
Subtracting 48 from 56 leaves us with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 16

Advancing to step 4:
If we divide 89 by 16, we get 5 and a remainder of 9.
The next digit of our result is 5. 
Result so far: 535.0
Deduct 80 from 89 and we're left with 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 16

Going ahead to step 5:
16 can be fit into 95 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 5355.0
If we subtract 80 from 95, we get 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 16

Advancing to step 6:
16 can be fit into 159 9 times, resulting in a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 53559.0
If we take 144 away from 159, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
If we divide 150 by 16, we get 9 and a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 53559.9
If we subtract 144 from 150, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
16 goes into 60 3 times with a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 53559.93
Subtracting 48 from 60 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.

Going ahead to step 9:
If we divide 120 by 16, we get 7 and a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 53559.937
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.

Let's proceed to step 10:
16 goes into 80 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 53559.9375
Subtracting 80 from 80 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.

On 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: 53559.9375
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.

Advancing to step 12:
16 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 53559.9375
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.

The final result is 53559.9375 with a remainder of 0.0.
