169224 ÷ 3 
The aim is to understand the frequency of 3 in 169224.

Advancing to step 1:
The number 3 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 3

Moving on to step 2:
3 can be fit into 16 5 times, resulting in a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 15 from 16 to get 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 3

Let's proceed to step 3:
When dividing 19 by 3, we get 6 with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 56.0
Subtract 18 from 19 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 3

Let's proceed to step 4:
When dividing 12 by 3, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 564.0
Subtracting 12 from 12 leaves us with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 3

Step 5:
If we divide 2 by 3, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 5640.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 3

Moving on to step 6:
If we divide 24 by 3, we get 8 and a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 56408.0
The remainder is 0 after subtracting 24 from 24.
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 7:
3 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 56408.0
If we subtract 0 from 0, 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.

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: 56408.0
If we subtract 0 from 0, 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.

Our division results in 56408.0 with a remaining 0.0.
