We divide 899710 by 3
The aim is to understand the frequency of 3 in 899710.

Let's proceed to step 1:
When dividing 8 by 3, we get 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 6 from 8 to get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 3

Moving on to step 2:
The number 3 fits into 29 9 times, leaving a remainder of 2.
The next digit of our result is 9. 
Result so far: 29.0
Deduct 27 from 29 and we're left with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 3

Step 3:
The number 3 fits into 29 9 times, leaving a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 299.0
The remainder is 2 after subtracting 27 from 29.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 3

Moving on to step 4:
3 goes into 27 9 times with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 2999.0
Subtracting 27 from 27 leaves us with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 3

Step 5:
3 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 29990.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 3

Going ahead to step 6:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 299903.0
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.

On to step 7:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 299903.3
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.

Moving on to step 8:
If we divide 10 by 3, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 299903.33
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.

The final outcome is 299903.33, with a leftover of 0.001.
