We're dividing 476618 by 3 
The aim is to understand the frequency of 3 in 476618.

Step 1:
If we divide 4 by 3, we get 1 and a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 3 from 4 to get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 3

Moving on to step 2:
If we divide 17 by 3, we get 5 and a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we subtract 15 from 17, we get 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 3

Advancing to step 3:
When dividing 26 by 3, we get 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 158.0
If we subtract 24 from 26, we get 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 3

Let's proceed to step 4:
When dividing 26 by 3, we get 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 1588.0
If we take 24 away from 26, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 3

Going ahead to step 5:
3 goes into 21 7 times with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 15887.0
The remainder is 0 after subtracting 21 from 21.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 3

Going ahead to step 6:
3 can be fit into 8 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 158872.0
The remainder is 2 after subtracting 6 from 8.
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 7:
If we divide 20 by 3, we get 6 and a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 158872.6
Subtract 18 from 20 to 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.

Let's proceed to step 8:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 158872.66
Subtract 18 from 20 to 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.

Our division results in 158872.66 with a remaining 0.002.
