We're dividing 604615 by 3 
The aim is to understand the frequency of 3 in 604615.

Advancing to step 1:
6 divided by 3 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 6 away from 6, we end up with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 3

Advancing to step 2:
If we divide 0 by 3, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtract 0 from 0 to get 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 3

Let's proceed to step 3:
3 goes into 4 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 201.0
Subtracting 3 from 4 leaves us with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 3

Step 4:
16 divided by 3 is 5 with a remainder of 1.
The next digit of our result is 5. 
Result so far: 2015.0
Subtracting 15 from 16 leaves us with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 3

Step 5:
11 divided by 3 is 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 20153.0
If we subtract 9 from 11, we get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 3

Moving on to step 6:
When dividing 25 by 3, we get 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 201538.0
Subtracting 24 from 25 leaves us 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.

Let's proceed to step 7:
If we divide 10 by 3, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 201538.3
Subtracting 9 from 10 leaves us 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.

Step 8:
When dividing 10 by 3, we get 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 201538.33
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.

After the division, we end up with 201538.33 and a remainder of 0.001.
