We divide 900289 by 3
The aim is to understand the frequency of 3 in 900289.

Moving on to step 1:
3 goes into 9 3 times with a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 0 after subtracting 9 from 9.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 3

Moving on to step 2:
When dividing 0 by 3, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Subtracting 0 from 0 leaves us with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 3

Step 3:
If we divide 0 by 3, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 300.0
If we subtract 0 from 0, we get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 3

Advancing to step 4:
If we divide 2 by 3, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 3000.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 3

Going ahead to step 5:
The number 3 fits into 28 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 30009.0
Subtract 27 from 28 to get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 3

Step 6:
3 goes into 19 6 times with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 300096.0
Deduct 18 from 19 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.

Step 7:
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: 300096.3
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.

Advancing to step 8:
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: 300096.33
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 300096.33 with a balance of 0.001.
