We look at the division of 432199 by 16 
The aim is to understand the frequency of 16 in 432199.

Let's proceed to step 1:
When dividing 4 by 16, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 16

Moving on to step 2:
The number 16 fits into 43 2 times, leaving a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 32 from 43, we get 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 16

Step 3:
112 divided by 16 is 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 27.0
Subtract 112 from 112 to get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 16

Step 4:
The number 16 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 270.0
If we subtract 0 from 1, we get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 16

Going ahead to step 5:
16 can be fit into 19 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 2701.0
Subtract 16 from 19 to get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 16

On to step 6:
When dividing 39 by 16, we get 2 with a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 27012.0
If we take 32 away from 39, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
If we divide 70 by 16, we get 4 and a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 27012.4
Deduct 64 from 70 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
The number 16 fits into 60 3 times, leaving a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 27012.43
Subtracting 48 from 60 leaves us 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.

Step 9:
16 can be fit into 120 7 times, resulting in a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 27012.437
If we take 112 away from 120, 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.

On to step 10:
When dividing 80 by 16, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 27012.4375
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.

Step 11:
16 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 27012.4375
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.

Going ahead to step 12:
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: 27012.4375
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.

The quotient of the division is 27012.4375, and the remainder is 0.0.
