488626 divided by 3 
The aim is to understand the frequency of 3 in 488626.

Going ahead to step 1:
The number 3 fits into 4 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 3 from 4 to get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 3

Let's proceed to step 2:
If we divide 18 by 3, we get 6 and a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we take 18 away from 18, we end up with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 3

Step 3:
3 can be fit into 8 2 times, resulting in a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 162.0
Subtracting 6 from 8 leaves us with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 3

Let's proceed to step 4:
When dividing 26 by 3, we get 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 1628.0
If we subtract 24 from 26, we get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 3

On to step 5:
The number 3 fits into 22 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 16287.0
Subtract 21 from 22 to get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 3

Let's proceed to step 6:
When dividing 16 by 3, we get 5 with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 162875.0
Subtract 15 from 16 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
3 goes into 10 3 times with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 162875.3
Subtract 9 from 10 to get 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 8:
The number 3 fits into 10 3 times, leaving a remainder of 1.
The next digit of our result is 3. 
Result so far: 162875.33
If we subtract 9 from 10, we get 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 162875.33 and a remainder of 0.001.
