990293 ÷ 1 
The aim is to understand the frequency of 1 in 990293.

Let's proceed to step 1:
When dividing 9 by 1, we get 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 9 from 9 to get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 1

Advancing to step 2:
If we divide 9 by 1, we get 9 and a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 99.0
Subtract 9 from 9 to get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Going ahead to step 3:
1 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 990.0
If we take 0 away from 0, we end up with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 1

Going ahead to step 4:
The number 1 fits into 2 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 9902.0
Subtracting 2 from 2 leaves us with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 1

Step 5:
The number 1 fits into 9 9 times, leaving a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 99029.0
If we subtract 9 from 9, we get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

Let's proceed to step 6:
1 goes into 3 3 times with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 990293.0
Subtract 3 from 3 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:
1 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 990293.0
Subtract 0 from 0 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.

Let's proceed to step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 990293.0
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.

The final outcome is 990293.0, with a leftover of 0.0.
