We look at the division of 813710 by 16 
The aim is to understand the frequency of 16 in 813710.

On to step 1:
8 divided by 16 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 16

Moving on to step 2:
When dividing 81 by 16, we get 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 80 from 81 leaves us with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 16

Step 3:
The number 16 fits into 13 0 times, leaving a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 50.0
The remainder is 13 after subtracting 0 from 13.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 16

Let's proceed to step 4:
If we divide 137 by 16, we get 8 and a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 508.0
Subtracting 128 from 137 leaves us with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 16

Step 5:
16 can be fit into 91 5 times, resulting in a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 5085.0
If we subtract 80 from 91, we get 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 16

Going ahead to step 6:
16 can be fit into 110 6 times, resulting in a remainder of 14.
The next digit of our result is 6. 
Result so far: 50856.0
Subtracting 96 from 110 leaves us 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.

Going ahead to step 7:
16 goes into 140 8 times with a remainder of 12.
The next digit of our result is 8. 
Result so far: 50856.8
If we take 128 away from 140, 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 can be fit into 120 7 times, resulting in a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 50856.87
Subtract 112 from 120 to 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 9:
16 can be fit into 80 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 50856.875
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.

Step 10:
The number 16 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 50856.875
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.

Step 11:
16 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 50856.875
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.

The final outcome is 50856.875, with a leftover of 0.0.
