488549 divided by 3 
The aim is to understand the frequency of 3 in 488549.

Advancing to step 1:
4 divided by 3 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 3 from 4 to get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 3

Advancing to step 2:
3 can be fit into 18 6 times, resulting in a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 16.0
Deduct 18 from 18 and we're left with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 3

Moving on to step 3:
3 can be fit into 8 2 times, resulting in a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 162.0
Deduct 6 from 8 and we're left with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 3

Going ahead to step 4:
If we divide 25 by 3, we get 8 and a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 1628.0
Subtract 24 from 25 to get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 3

Let's proceed to step 5:
If we divide 14 by 3, we get 4 and a remainder of 2.
The next digit of our result is 4. 
Result so far: 16284.0
The remainder is 2 after subtracting 12 from 14.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 3

Step 6:
3 goes into 29 9 times with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 162849.0
If we subtract 27 from 29, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
The number 3 fits into 20 6 times, leaving a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 162849.6
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
3 goes into 20 6 times with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 162849.66
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 162849.66, and the remainder is 0.002.
