We divide 163495 by 3
The aim is to understand the frequency of 3 in 163495.

Let's proceed to step 1:
If we divide 1 by 3, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 3

Advancing to step 2:
When dividing 16 by 3, we get 5 with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 1 after subtracting 15 from 16.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 3

Let's proceed to step 3:
3 goes into 13 4 times with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 54.0
Deduct 12 from 13 and we're left with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 3

Advancing to step 4:
The number 3 fits into 14 4 times, leaving a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 544.0
If we take 12 away from 14, we end up with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 3

Step 5:
29 divided by 3 is 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 5449.0
Subtract 27 from 29 to get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 3

Going ahead to step 6:
3 can be fit into 25 8 times, resulting in a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 54498.0
If we subtract 24 from 25, 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.

Advancing to step 7:
If we divide 10 by 3, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 54498.3
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.

Step 8:
10 divided by 3 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 54498.33
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 54498.33 and a remainder of 0.001.
