We look at the division of 648395 by 3 
The aim is to understand the frequency of 3 in 648395.

On to step 1:
3 can be fit into 6 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 0 after subtracting 6 from 6.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 3

Going ahead to step 2:
If we divide 4 by 3, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtracting 3 from 4 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 3

Advancing to step 3:
18 divided by 3 is 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 216.0
Subtract 18 from 18 to get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 3

Advancing to step 4:
When dividing 3 by 3, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 2161.0
If we subtract 3 from 3, we get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 3

Going ahead to step 5:
If we divide 9 by 3, we get 3 and a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 21613.0
Subtracting 9 from 9 leaves us with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 3

Let's proceed to step 6:
If we divide 5 by 3, we get 1 and a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 216131.0
Subtracting 3 from 5 leaves us 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:
20 divided by 3 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 216131.6
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.

Moving on 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: 216131.66
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.

In conclusion, the division gives 216131.66 with a balance of 0.002.
