We look at the division of 441404 by 16 
The aim is to understand the frequency of 16 in 441404.

Step 1:
When dividing 4 by 16, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 16

Going ahead to step 2:
16 can be fit into 44 2 times, resulting in a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 32 from 44 to get 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 16

Moving on to step 3:
When dividing 121 by 16, we get 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Subtract 112 from 121 to get 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 16

Advancing to step 4:
The number 16 fits into 94 5 times, leaving a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 275.0
If we subtract 80 from 94, we get 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 16

Step 5:
When dividing 140 by 16, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 2758.0
Subtract 128 from 140 to get 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 16

Step 6:
When dividing 124 by 16, we get 7 with a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 27587.0
If we take 112 away from 124, we end up 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.

Advancing to step 7:
The number 16 fits into 120 7 times, leaving a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 27587.7
If we subtract 112 from 120, we 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 8:
The number 16 fits into 80 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 27587.75
Subtract 80 from 80 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.

Going ahead to step 9:
16 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 27587.75
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.

Let's proceed to step 10:
0 divided by 16 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 27587.75
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.

Our division results in 27587.75 with a remaining 0.0.
