We look at the division of 613218 by 3 
The aim is to understand the frequency of 3 in 613218.

Let's proceed to step 1:
When dividing 6 by 3, we get 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 6 from 6 to get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 3

Going ahead to step 2:
The number 3 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 3

Let's proceed to step 3:
3 can be fit into 13 4 times, resulting in a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 204.0
The remainder is 1 after subtracting 12 from 13.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 3

On to step 4:
If we divide 12 by 3, we get 4 and a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 2044.0
Subtracting 12 from 12 leaves us with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 3

Advancing to step 5:
3 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 20440.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 3

Moving on to step 6:
3 goes into 18 6 times with a remainder of 0.
The next digit of our result is 6. 
Result so far: 204406.0
Subtract 18 from 18 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.

Going ahead to step 7:
If we divide 0 by 3, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 204406.0
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.

Moving on to step 8:
0 divided by 3 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 204406.0
If we take 0 away from 0, we end up 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.

In conclusion, the division gives 204406.0 with a balance of 0.0.
