636778 divided by 16 
The aim is to understand the frequency of 16 in 636778.

Moving 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
The remainder is 6 after subtracting 0 from 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 16

Advancing to step 2:
When dividing 63 by 16, we get 3 with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 15 after subtracting 48 from 63.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 16

On to step 3:
If we divide 156 by 16, we get 9 and a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 39.0
If we subtract 144 from 156, we get 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 16

Step 4:
127 divided by 16 is 7 with a remainder of 15.
The next digit of our result is 7. 
Result so far: 397.0
The remainder is 15 after subtracting 112 from 127.
Append the next digit (7) from the dividend to 15 and continue with: 157 / 16

Going ahead to step 5:
157 divided by 16 is 9 with a remainder of 13.
The next digit of our result is 9. 
Result so far: 3979.0
If we take 144 away from 157, we end up with 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 16

Moving on to step 6:
If we divide 138 by 16, we get 8 and a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 39798.0
The remainder is 10 after subtracting 128 from 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
16 goes into 100 6 times with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 39798.6
Subtracting 96 from 100 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
If we divide 40 by 16, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 39798.62
If we take 32 away from 40, we end up 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.

Step 9:
If we divide 80 by 16, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 39798.625
Subtracting 80 from 80 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 10:
16 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 39798.625
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 11:
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: 39798.625
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 quotient of the division is 39798.625, and the remainder is 0.0.
