We're dividing 86366271 by 16 
The aim is to understand the frequency of 16 in 86366271.

Let's proceed to step 1:
16 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 16

On to step 2:
The number 16 fits into 86 5 times, leaving a remainder of 6.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 80 from 86 leaves us with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 16

Let's proceed to step 3:
63 divided by 16 is 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 53.0
If we subtract 48 from 63, we get 15.
Bring next digit (6) of the dividend behind the 15 and repeat the process: 156 / 16

Step 4:
The number 16 fits into 156 9 times, leaving a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 539.0
Deduct 144 from 156 and we're left with 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 16

Moving on to step 5:
16 can be fit into 126 7 times, resulting in a remainder of 14.
The next digit of our result is 7. 
Result so far: 5397.0
If we subtract 112 from 126, we get 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 16

Moving on to step 6:
16 can be fit into 142 8 times, resulting in a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 53978.0
Deduct 128 from 142 and we're left with 14.
Fetch the next digit (7) from the dividend, attach it to 14 and continue: 147 / 16

On to step 7:
When dividing 147 by 16, we get 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 539789.0
The remainder is 3 after subtracting 144 from 147.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 16

Let's proceed to step 8:
The number 16 fits into 31 1 times, leaving a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 5397891.0
The remainder is 15 after subtracting 16 from 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
16 can be fit into 150 9 times, resulting in a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 5397891.9
If we take 144 away from 150, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
60 divided by 16 is 3 with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 5397891.93
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.

Step 11:
If we divide 120 by 16, we get 7 and a remainder of 8.
The next digit of our result is 7. 
Result so far: 5397891.937
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.

Moving on to step 12:
The number 16 fits into 80 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 5397891.9375
The remainder is 0 after subtracting 80 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 13:
16 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5397891.9375
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.

Advancing to step 14:
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: 5397891.9375
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.

After the division, we end up with 5397891.9375 and a remainder of 0.0.
