We're dividing 609401 by 16 
The aim is to understand the frequency of 16 in 609401.

Moving on to step 1:
6 divided by 16 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 16

Let's proceed to step 2:
If we divide 60 by 16, we get 3 and a remainder of 12.
The next digit of our result is 3. 
Result so far: 3.0
If we take 48 away from 60, we end up with 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 16

Advancing to step 3:
129 divided by 16 is 8 with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 38.0
If we subtract 128 from 129, we get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 16

Step 4:
The number 16 fits into 14 0 times, leaving a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 380.0
If we subtract 0 from 14, we get 14.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 16

Going ahead to step 5:
The number 16 fits into 140 8 times, leaving a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 3808.0
If we subtract 128 from 140, we get 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 16

Moving on to step 6:
If we divide 121 by 16, we get 7 and a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 38087.0
If we subtract 112 from 121, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
If we divide 90 by 16, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 38087.5
If we take 80 away from 90, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
16 goes into 100 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 38087.56
The remainder is 4 after subtracting 96 from 100.
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:
The number 16 fits into 40 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 38087.562
The remainder is 8 after subtracting 32 from 40.
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:
When dividing 80 by 16, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 38087.5625
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:
0 divided by 16 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 38087.5625
Subtracting 0 from 0 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.

Going ahead 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: 38087.5625
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.

The final outcome is 38087.5625, with a leftover of 0.0.
