We look at the division of 65487 by 3 
The aim is to understand the frequency of 3 in 65487.

Going ahead to step 1:
3 goes into 6 2 times with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 0 after subtracting 6 from 6.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 3

Moving on to step 2:
The number 3 fits into 5 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we subtract 3 from 5, we get 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 3

On to step 3:
If we divide 24 by 3, we get 8 and a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 218.0
If we take 24 away from 24, we end up with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 3

Advancing to step 4:
If we divide 8 by 3, we get 2 and a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2182.0
If we take 6 away from 8, we end up with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 3

Step 5:
If we divide 27 by 3, we get 9 and a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 21829.0
Subtract 27 from 27 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.

Moving on to step 6:
3 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 21829.0
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.

Step 7:
3 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 21829.0
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.

After the division, we end up with 21829.0 and a remainder of 0.0.
