854405 divided by 16 
The aim is to understand the frequency of 16 in 854405.

Going ahead to step 1:
The number 16 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 16

Going ahead to step 2:
The number 16 fits into 85 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 80 from 85, we get 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 16

Let's proceed to step 3:
16 can be fit into 54 3 times, resulting in a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
If we take 48 away from 54, we end up with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 16

Going ahead to step 4:
16 can be fit into 64 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 534.0
Subtract 64 from 64 to get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 16

On to step 5:
16 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5340.0
If we subtract 0 from 0, we get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 16

Going ahead to step 6:
The number 16 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 53400.0
If we subtract 0 from 5, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
16 can be fit into 50 3 times, resulting in a remainder of 2.
The next digit of our result is 3. 
Result so far: 53400.3
The remainder is 2 after subtracting 48 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
16 goes into 20 1 times with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 53400.31
Subtracting 16 from 20 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
16 can be fit into 40 2 times, resulting in a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 53400.312
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.

On to step 10:
80 divided by 16 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 53400.3125
The remainder is 0 after subtracting 80 from 80.
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:
0 divided by 16 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 53400.3125
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.

On to step 12:
If we divide 0 by 16, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 53400.3125
Deduct 0 from 0 and we're left 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 53400.3125, with a leftover of 0.0.
