Let's divide 780902 by 1
The aim is to understand the frequency of 1 in 780902.

Moving on to step 1:
If we divide 7 by 1, we get 7 and a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 7 from 7, we get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

Let's proceed to step 2:
1 goes into 8 8 times with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 78.0
Deduct 8 from 8 and we're left with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 1

Moving on to step 3:
1 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 780.0
The remainder is 0 after subtracting 0 from 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 1

Let's proceed to step 4:
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: 7809.0
Deduct 9 from 9 and we're left with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 1

On to step 5:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 78090.0
Subtract 0 from 0 to get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 1

Step 6:
2 divided by 1 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 780902.0
The remainder is 0 after subtracting 2 from 2.
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:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 780902.0
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.

On to step 8:
When dividing 0 by 1, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 780902.0
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.

In conclusion, the division gives 780902.0 with a balance of 0.0.
