239729 divided by 3 
The aim is to understand the frequency of 3 in 239729.

Let's proceed to step 1:
3 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 3

Step 2:
When dividing 23 by 3, we get 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 21 from 23 to get 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 3

Going ahead to step 3:
The number 3 fits into 29 9 times, leaving a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 79.0
Subtracting 27 from 29 leaves us with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 3

On to step 4:
The number 3 fits into 27 9 times, leaving a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 799.0
If we subtract 27 from 27, we get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 3

On to step 5:
The number 3 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 7990.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 3

Going ahead to step 6:
29 divided by 3 is 9 with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 79909.0
Deduct 27 from 29 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
If we divide 20 by 3, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 79909.6
Subtracting 18 from 20 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
The number 3 fits into 20 6 times, leaving a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 79909.66
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 79909.66 with a remainder of 0.002.
