433738 ÷ 3 
The aim is to understand the frequency of 3 in 433738.

Moving on 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
The remainder is 1 after subtracting 3 from 4.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 3

Let's proceed to step 2:
The number 3 fits into 13 4 times, leaving a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtract 12 from 13 to get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 3

On to step 3:
The number 3 fits into 13 4 times, leaving a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 144.0
If we take 12 away from 13, we end up with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 3

Advancing to step 4:
3 can be fit into 17 5 times, resulting in a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 1445.0
Subtracting 15 from 17 leaves us with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 3

Step 5:
The number 3 fits into 23 7 times, leaving a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 14457.0
Deduct 21 from 23 and we're left with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 3

Advancing to step 6:
If we divide 28 by 3, we get 9 and a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 144579.0
If we take 27 away from 28, we end up 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.

Moving on to step 7:
3 can be fit into 10 3 times, resulting in a remainder of 1.
The next digit of our result is 3. 
Result so far: 144579.3
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.

On to step 8:
When dividing 10 by 3, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 144579.33
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.

The quotient of the division is 144579.33, and the remainder is 0.001.
