We're dividing 407200 by 16 
The aim is to understand the frequency of 16 in 407200.

Going ahead to step 1:
16 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 16

On to step 2:
16 goes into 40 2 times with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 32 away from 40, we end up with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 16

Advancing to step 3:
The number 16 fits into 87 5 times, leaving a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 25.0
If we take 80 away from 87, we end up with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 16

Step 4:
72 divided by 16 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 254.0
Deduct 64 from 72 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 16

Moving on to step 5:
If we divide 80 by 16, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 2545.0
The remainder is 0 after subtracting 80 from 80.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 16

Moving on to step 6:
16 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 25450.0
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.

Going ahead to step 7:
16 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 25450.0
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.

Let's proceed to step 8:
16 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 25450.0
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 25450.0, with a leftover of 0.0.
