We're dividing 15490 by 16 
The aim is to understand the frequency of 16 in 15490.

On to step 1:
The number 16 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 16

Advancing to step 2:
If we divide 15 by 16, we get 0 and a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 16

Advancing to step 3:
The number 16 fits into 154 9 times, leaving a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 144 from 154, we get 10.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 16

On to step 4:
The number 16 fits into 109 6 times, leaving a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 96.0
Subtract 96 from 109 to get 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 16

Moving on to step 5:
16 goes into 130 8 times with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 968.0
Subtracting 128 from 130 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 6:
The number 16 fits into 20 1 times, leaving a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 968.1
Subtract 16 from 20 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
The number 16 fits into 40 2 times, leaving a remainder of 8.
The next digit of our result is 2. 
Result so far: 968.12
Deduct 32 from 40 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.

Let's proceed to step 8:
If we divide 80 by 16, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 968.125
If we subtract 80 from 80, 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 9:
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: 968.125
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.

Step 10:
If we divide 0 by 16, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 968.125
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 968.125 and a remainder of 0.0.
