We look at the division of 639180 by 3 
The aim is to understand the frequency of 3 in 639180.

Moving on to step 1:
The number 3 fits into 6 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 6 away from 6, we end up with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 3

On to step 2:
The number 3 fits into 3 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 21.0
The remainder is 0 after subtracting 3 from 3.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 3

Step 3:
9 divided by 3 is 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 213.0
Subtract 9 from 9 to get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 3

Let's proceed to step 4:
3 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 2130.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 3

Moving on to step 5:
If we divide 18 by 3, we get 6 and a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 21306.0
Deduct 18 from 18 and we're left with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 3

Advancing to step 6:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 213060.0
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.

Going ahead to step 7:
0 divided by 3 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 213060.0
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.

Let's proceed to step 8:
If we divide 0 by 3, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 213060.0
Subtract 0 from 0 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.

In conclusion, the division gives 213060.0 with a balance of 0.0.
