608172 ÷ 3 
The aim is to understand the frequency of 3 in 608172.

Let's proceed to step 1:
The number 3 fits into 6 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 0 after subtracting 6 from 6.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 3

Step 2:
0 divided by 3 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we take 0 away from 0, we end up with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 3

Moving on to step 3:
If we divide 8 by 3, we get 2 and a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 202.0
If we take 6 away from 8, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 3

Advancing to step 4:
If we divide 21 by 3, we get 7 and a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 2027.0
If we take 21 away from 21, we end up with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 3

Let's proceed to step 5:
If we divide 7 by 3, we get 2 and a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 20272.0
If we subtract 6 from 7, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 3

Advancing to step 6:
When dividing 12 by 3, we get 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 202724.0
If we subtract 12 from 12, we 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.

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: 202724.0
Deduct 0 from 0 and we're left 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:
When dividing 0 by 3, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 202724.0
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.

The final result is 202724.0 with a remainder of 0.0.
