990289 ÷ 1 
The aim is to understand the frequency of 1 in 990289.

Let's proceed to step 1:
When dividing 9 by 1, we get 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 9 from 9 leaves us with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 1

Advancing to step 2:
When dividing 9 by 1, we get 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 99.0
If we subtract 9 from 9, we get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 1

Moving on to step 3:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 990.0
Deduct 0 from 0 and we're left with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 1

Let's proceed to step 4:
2 divided by 1 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 9902.0
If we take 2 away from 2, we end up with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 1

Step 5:
When dividing 8 by 1, we get 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 99028.0
Deduct 8 from 8 and we're left with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 1

Moving on to step 6:
The number 1 fits into 9 9 times, leaving a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 990289.0
Subtract 9 from 9 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
When dividing 0 by 1, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 990289.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
When dividing 0 by 1, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 990289.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 990289.0 with a remaining 0.0.
