We divide 285379 by 3
The aim is to understand the frequency of 3 in 285379.

On 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
The remainder is 2 after subtracting 0 from 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 3

Advancing to step 2:
3 can be fit into 28 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 27 from 28 to get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 3

Let's proceed to step 3:
15 divided by 3 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 95.0
If we subtract 15 from 15, we get 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 3

Step 4:
3 can be fit into 3 1 times, resulting in a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 951.0
The remainder is 0 after subtracting 3 from 3.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 3

Going ahead to step 5:
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: 9512.0
If we subtract 6 from 7, we get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 3

Advancing to step 6:
3 can be fit into 19 6 times, resulting in a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 95126.0
If we subtract 18 from 19, we 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.

Step 7:
If we divide 10 by 3, we get 3 and a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 95126.3
If we subtract 9 from 10, we 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.

Going ahead to step 8:
If we divide 10 by 3, we get 3 and a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 95126.33
Subtracting 9 from 10 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.

In conclusion, the division gives 95126.33 with a balance of 0.001.
