We look at the division of 187993 by 16 
The aim is to understand the frequency of 16 in 187993.

Going ahead to step 1:
When dividing 1 by 16, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 16

Advancing to step 2:
18 divided by 16 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 16 from 18 to get 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 16

On to step 3:
27 divided by 16 is 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 16 from 27, we get 11.
Grab the next digit (9) from the dividend, add it to 11, then carry on: 119 / 16

On to step 4:
16 goes into 119 7 times with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 117.0
If we take 112 away from 119, we end up with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 16

Moving on to step 5:
When dividing 79 by 16, we get 4 with a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 1174.0
Deduct 64 from 79 and we're left with 15.
Take the next digit (3) from the dividend and append it to 15, then repeat: 153 / 16

Going ahead to step 6:
153 divided by 16 is 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 11749.0
The remainder is 9 after subtracting 144 from 153.
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:
When dividing 90 by 16, we get 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 11749.5
Subtract 80 from 90 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
The number 16 fits into 100 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 11749.56
Subtracting 96 from 100 leaves us 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.

Advancing to step 9:
16 goes into 40 2 times with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 11749.562
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.

Moving on to step 10:
16 goes into 80 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 11749.5625
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.

On to step 11:
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: 11749.5625
If we subtract 0 from 0, we 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.

Moving on to step 12:
16 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 11749.5625
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.

After the division, we end up with 11749.5625 and a remainder of 0.0.
