544681 divided by 16 
The aim is to understand the frequency of 16 in 544681.

Advancing to step 1:
If we divide 5 by 16, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 16

On to step 2:
If we divide 54 by 16, we get 3 and a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 48 from 54 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 16

Advancing to step 3:
When dividing 64 by 16, we get 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 34.0
The remainder is 0 after subtracting 64 from 64.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 16

Going ahead to step 4:
The number 16 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 340.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 16

On to step 5:
68 divided by 16 is 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 3404.0
Subtracting 64 from 68 leaves us with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 16

Advancing to step 6:
16 goes into 41 2 times with a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 34042.0
If we take 32 away from 41, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
The number 16 fits into 90 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 34042.5
The remainder is 10 after subtracting 80 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
When dividing 100 by 16, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 34042.56
The remainder is 4 after subtracting 96 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
16 goes into 40 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 34042.562
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.

Going ahead to step 10:
If we divide 80 by 16, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 34042.5625
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.

Going ahead to step 11:
0 divided by 16 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 34042.5625
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 12:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 34042.5625
Subtract 0 from 0 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.

Our division results in 34042.5625 with a remaining 0.0.
