We look at the division of 3510 by 16 
The aim is to understand the frequency of 16 in 3510.

Advancing to step 1:
16 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 16

Moving on to step 2:
If we divide 35 by 16, we get 2 and a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 32 from 35, we get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 16

Moving on to step 3:
16 goes into 31 1 times with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Deduct 16 from 31 and we're left with 15.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 16

On to step 4:
The number 16 fits into 150 9 times, leaving a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 219.0
Deduct 144 from 150 and we're left 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.

On to step 5:
The number 16 fits into 60 3 times, leaving a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 219.3
The remainder is 12 after subtracting 48 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 6:
16 goes into 120 7 times with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 219.37
Subtract 112 from 120 to 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 7:
80 divided by 16 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 219.375
If we take 80 away from 80, 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.

Moving on to step 8:
0 divided by 16 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 219.375
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.

Moving on to step 9:
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: 219.375
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.

Our division results in 219.375 with a remaining 0.0.
