We look at the division of 619027 by 3 
The aim is to understand the frequency of 3 in 619027.

Step 1:
3 goes into 6 2 times with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 6 from 6 leaves us with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 3

Let's proceed to step 2:
1 divided by 3 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 3

Advancing to step 3:
3 can be fit into 19 6 times, resulting in a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 206.0
Subtract 18 from 19 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 3

Step 4:
10 divided by 3 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 2063.0
If we take 9 away from 10, we end up with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 3

Moving on to step 5:
When dividing 12 by 3, we get 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 20634.0
If we subtract 12 from 12, we get 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 3

Going ahead to step 6:
If we divide 7 by 3, we get 2 and a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 206342.0
The remainder is 1 after subtracting 6 from 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 206342.3
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 8:
If we divide 10 by 3, we get 3 and a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 206342.33
Deduct 9 from 10 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 206342.33 and a remainder of 0.001.
