628299 divided by 16 
The aim is to understand the frequency of 16 in 628299.

On to step 1:
When dividing 6 by 16, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 16

Advancing to step 2:
When dividing 62 by 16, we get 3 with a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 48 from 62 leaves us with 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 16

On to step 3:
The number 16 fits into 148 9 times, leaving a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 39.0
Deduct 144 from 148 and we're left with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 16

On to step 4:
When dividing 42 by 16, we get 2 with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 392.0
The remainder is 10 after subtracting 32 from 42.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 16

Let's proceed to step 5:
109 divided by 16 is 6 with a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 3926.0
Deduct 96 from 109 and we're left with 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 16

On to step 6:
16 can be fit into 139 8 times, resulting in a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 39268.0
Subtract 128 from 139 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
16 goes into 110 6 times with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 39268.6
Subtract 96 from 110 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
16 can be fit into 140 8 times, resulting in a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 39268.68
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.

Step 9:
120 divided by 16 is 7 with a remainder of 8.
The next digit of our result is 7. 
Result so far: 39268.687
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.

Moving on to step 10:
The number 16 fits into 80 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 39268.6875
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.

Advancing to step 11:
0 divided by 16 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 39268.6875
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.
Use 0 as the next digit of our solution. 
Result so far: 39268.6875
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 39268.6875, with a leftover of 0.0.
