We look at the division of 430752 by 3 
The aim is to understand the frequency of 3 in 430752.

Moving on to step 1:
3 goes into 4 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 3 from 4 to get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 3

Step 2:
When dividing 13 by 3, we get 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 1 after subtracting 12 from 13.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 3

Moving on to step 3:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 143.0
Deduct 9 from 10 and we're left with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 3

On to step 4:
3 can be fit into 17 5 times, resulting in a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 1435.0
If we subtract 15 from 17, we get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 3

Going ahead to step 5:
When dividing 25 by 3, we get 8 with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 14358.0
The remainder is 1 after subtracting 24 from 25.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 3

Step 6:
3 goes into 12 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 143584.0
Subtract 12 from 12 to 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 7:
3 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 143584.0
Subtract 0 from 0 to 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.

Moving on to step 8:
When dividing 0 by 3, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 143584.0
If we take 0 away from 0, we end up 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.

After the division, we end up with 143584.0 and a remainder of 0.0.
