We divide 989078 by 3
The aim is to understand the frequency of 3 in 989078.

Let's proceed to step 1:
3 goes into 9 3 times with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 9 from 9 and we're left with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 3

On to step 2:
If we divide 8 by 3, we get 2 and a remainder of 2.
The next digit of our result is 2. 
Result so far: 32.0
The remainder is 2 after subtracting 6 from 8.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 3

Advancing to step 3:
If we divide 29 by 3, we get 9 and a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 329.0
Subtract 27 from 29 to get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 3

On to step 4:
20 divided by 3 is 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 3296.0
If we subtract 18 from 20, we get 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 3

Step 5:
The number 3 fits into 27 9 times, leaving a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 32969.0
If we take 27 away from 27, we end up with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 3

Step 6:
8 divided by 3 is 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 329692.0
If we subtract 6 from 8, we 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.

Going ahead to step 7:
The number 3 fits into 20 6 times, leaving a remainder of 2.
The next digit of our result is 6. 
Result so far: 329692.6
If we subtract 18 from 20, we 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.

Step 8:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 329692.66
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.

In conclusion, the division gives 329692.66 with a balance of 0.002.
