We're dividing 549059 by 3 
The aim is to understand the frequency of 3 in 549059.

Going ahead to step 1:
3 goes into 5 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 3 from 5 leaves us with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 3

Let's proceed to step 2:
24 divided by 3 is 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 18.0
Subtracting 24 from 24 leaves us with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 3

On to step 3:
The number 3 fits into 9 3 times, leaving a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 183.0
The remainder is 0 after subtracting 9 from 9.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 3

On to step 4:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1830.0
The remainder is 0 after subtracting 0 from 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 3

Step 5:
When dividing 5 by 3, we get 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 18301.0
Subtract 3 from 5 to get 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 3

Moving on to step 6:
3 goes into 29 9 times with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 183019.0
If we take 27 away from 29, 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.

On to step 7:
When dividing 20 by 3, we get 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 183019.6
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.

Let's proceed to step 8:
3 goes into 20 6 times with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 183019.66
If we subtract 18 from 20, 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.

After the division, we end up with 183019.66 and a remainder of 0.002.
