We look at the division of 13039 by 16 
The aim is to understand the frequency of 16 in 13039.

On to step 1:
If we divide 1 by 16, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 16

Let's proceed to step 2:
If we divide 13 by 16, we get 0 and a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 16

Going ahead to step 3:
When dividing 130 by 16, we get 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 128 away from 130, we end up with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 16

Moving on to step 4:
The number 16 fits into 23 1 times, leaving a remainder of 7.
The next digit of our result is 1. 
Result so far: 81.0
If we take 16 away from 23, we end up with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 16

Step 5:
16 can be fit into 79 4 times, resulting in a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 814.0
The remainder is 15 after subtracting 64 from 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 6:
When dividing 150 by 16, we get 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 814.9
Subtract 144 from 150 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
When dividing 60 by 16, we get 3 with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 814.93
If we take 48 away from 60, we end up 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.

Moving on to step 8:
16 goes into 120 7 times with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 814.937
Deduct 112 from 120 and we're left 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.

Going ahead to step 9:
When dividing 80 by 16, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 814.9375
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.

Step 10:
16 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 814.9375
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.

On to step 11:
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: 814.9375
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.

The quotient of the division is 814.9375, and the remainder is 0.0.
