We're dividing 823699 by 16 
The aim is to understand the frequency of 16 in 823699.

Advancing to step 1:
16 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 16

Let's proceed to step 2:
16 goes into 82 5 times with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 80 from 82, we get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 16

Let's proceed to step 3:
If we divide 23 by 16, we get 1 and a remainder of 7.
The next digit of our result is 1. 
Result so far: 51.0
If we subtract 16 from 23, we get 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 16

On to step 4:
The number 16 fits into 76 4 times, leaving a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 514.0
Subtract 64 from 76 to get 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 16

Advancing to step 5:
When dividing 129 by 16, we get 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 5148.0
If we take 128 away from 129, we end up with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 16

Moving on to step 6:
16 can be fit into 19 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 51481.0
Deduct 16 from 19 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
16 goes into 30 1 times with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 51481.1
Deduct 16 from 30 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
The number 16 fits into 140 8 times, leaving a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 51481.18
The remainder is 12 after subtracting 128 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
16 goes into 120 7 times with a remainder of 8.
The next digit of our result is 7. 
Result so far: 51481.187
Subtracting 112 from 120 leaves us 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.

Advancing 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: 51481.1875
Deduct 80 from 80 and we're left 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 11:
0 divided by 16 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 51481.1875
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 12:
When dividing 0 by 16, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 51481.1875
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 result is 51481.1875 with a remainder of 0.0.
