We look at the division of 971709 by 16 
The aim is to understand the frequency of 16 in 971709.

Step 1:
9 divided by 16 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 16

Going ahead to step 2:
The number 16 fits into 97 6 times, leaving a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 96 from 97, we get 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 16

Let's proceed to step 3:
When dividing 11 by 16, we get 0 with a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 60.0
Subtract 0 from 11 to get 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 16

Moving on to step 4:
16 goes into 117 7 times with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 607.0
If we take 112 away from 117, we end up with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 16

Going ahead to step 5:
16 can be fit into 50 3 times, resulting in a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 6073.0
The remainder is 2 after subtracting 48 from 50.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 16

Advancing to step 6:
When dividing 29 by 16, we get 1 with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 60731.0
The remainder is 13 after subtracting 16 from 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
16 goes into 130 8 times with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 60731.8
If we subtract 128 from 130, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
When dividing 20 by 16, we get 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 60731.81
The remainder is 4 after subtracting 16 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
16 goes into 40 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 60731.812
If we subtract 32 from 40, we get 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.
The number 5 becomes the next digit in our result. 
Result so far: 60731.8125
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.

Advancing to step 11:
When dividing 0 by 16, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 60731.8125
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.

Let's proceed to step 12:
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: 60731.8125
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.

The final outcome is 60731.8125, with a leftover of 0.0.
