899320 ÷ 3 
The aim is to understand the frequency of 3 in 899320.

Going ahead to step 1:
If we divide 8 by 3, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 6 from 8, we get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 3

Moving on to step 2:
3 goes into 29 9 times with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 29.0
Subtracting 27 from 29 leaves us with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 3

Step 3:
3 goes into 29 9 times with a remainder of 2.
The next digit of our result is 9. 
Result so far: 299.0
The remainder is 2 after subtracting 27 from 29.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 3

Advancing to step 4:
3 can be fit into 23 7 times, resulting in a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 2997.0
Subtract 21 from 23 to get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 3

Advancing to step 5:
3 goes into 22 7 times with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 29977.0
If we subtract 21 from 22, we get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 3

Step 6:
3 goes into 10 3 times with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 299773.0
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.

Step 7:
10 divided by 3 is 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 299773.3
If we take 9 away from 10, we end up 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.

On to step 8:
10 divided by 3 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 299773.33
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.

The quotient of the division is 299773.33, and the remainder is 0.001.
