We look at the division of 550402 by 16 
The aim is to understand the frequency of 16 in 550402.

On to step 1:
If we divide 5 by 16, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 16

Going ahead to step 2:
The number 16 fits into 55 3 times, leaving a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 48 from 55, we get 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 16

Moving on to step 3:
The number 16 fits into 70 4 times, leaving a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
Deduct 64 from 70 and we're left with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 16

Let's proceed to step 4:
When dividing 64 by 16, we get 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 344.0
Deduct 64 from 64 and we're left with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 16

Going ahead to step 5:
The number 16 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3440.0
Deduct 0 from 0 and we're left with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 16

Moving on to step 6:
The number 16 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 34400.0
The remainder is 2 after subtracting 0 from 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
20 divided by 16 is 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 34400.1
If we take 16 away from 20, we end up 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 8:
40 divided by 16 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 34400.12
If we take 32 away from 40, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
16 goes into 80 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 34400.125
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.

Moving on to step 10:
If we divide 0 by 16, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 34400.125
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.

Moving on to step 11:
0 divided by 16 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 34400.125
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 34400.125 with a remainder of 0.0.
