639008 divided by 16 
The aim is to understand the frequency of 16 in 639008.

On to step 1:
16 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 16

Advancing to step 2:
The number 16 fits into 63 3 times, leaving a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 48 from 63, we get 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 16

Let's proceed to step 3:
When dividing 159 by 16, we get 9 with a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 39.0
If we subtract 144 from 159, we get 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 16

Let's proceed to step 4:
When dividing 150 by 16, we get 9 with a remainder of 6.
The next digit of our result is 9. 
Result so far: 399.0
The remainder is 6 after subtracting 144 from 150.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 16

Step 5:
If we divide 60 by 16, we get 3 and a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 3993.0
If we take 48 away from 60, we end up with 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 16

Advancing to step 6:
128 divided by 16 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 39938.0
Subtract 128 from 128 to 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 7:
0 divided by 16 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 39938.0
The remainder is 0 after subtracting 0 from 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 8:
0 divided by 16 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 39938.0
The remainder is 0 after subtracting 0 from 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 quotient of the division is 39938.0, and the remainder is 0.0.
