732466 divided by 3 
The aim is to understand the frequency of 3 in 732466.

On to step 1:
The number 3 fits into 7 2 times, leaving a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 6 from 7 and we're left with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 3

On to step 2:
13 divided by 3 is 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
If we subtract 12 from 13, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 3

Moving on to step 3:
3 can be fit into 12 4 times, resulting in a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 244.0
Subtract 12 from 12 to get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 3

Step 4:
If we divide 4 by 3, we get 1 and a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 2441.0
The remainder is 1 after subtracting 3 from 4.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 3

Advancing to step 5:
The number 3 fits into 16 5 times, leaving a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 24415.0
If we subtract 15 from 16, we get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 3

Step 6:
3 can be fit into 16 5 times, resulting in a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 244155.0
Subtracting 15 from 16 leaves us 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:
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: 244155.3
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.

Moving on to step 8:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 244155.33
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 244155.33 with a remaining 0.001.
