We divide 806639 by 16
The aim is to understand the frequency of 16 in 806639.

Let's proceed to step 1:
The number 16 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 16

Let's proceed to step 2:
16 can be fit into 80 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 0 after subtracting 80 from 80.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 16

Let's proceed to step 3:
When dividing 6 by 16, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 50.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 16

On to step 4:
If we divide 66 by 16, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 504.0
If we subtract 64 from 66, we get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 16

Step 5:
If we divide 23 by 16, we get 1 and a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 5041.0
The remainder is 7 after subtracting 16 from 23.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 16

Step 6:
The number 16 fits into 79 4 times, leaving a remainder of 15.
Record the quotient 4 as the next digit in the result. 
Result so far: 50414.0
Deduct 64 from 79 and we're left with 15.
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 7:
The number 16 fits into 150 9 times, leaving a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 50414.9
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.

Let's proceed to step 8:
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: 50414.93
Subtract 48 from 60 to get 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 9:
If we divide 120 by 16, we get 7 and a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 50414.937
If we subtract 112 from 120, 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:
The number 16 fits into 80 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 50414.9375
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 11:
When dividing 0 by 16, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 50414.9375
Subtracting 0 from 0 leaves us 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.

Going ahead to step 12:
0 divided by 16 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 50414.9375
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.

The final outcome is 50414.9375, with a leftover of 0.0.
