720359 ÷ 1 
The aim is to understand the frequency of 1 in 720359.

Step 1:
The number 1 fits into 7 7 times, leaving a remainder of 0.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 7 from 7 leaves us with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 1

Step 2:
1 goes into 2 2 times with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 72.0
Subtracting 2 from 2 leaves us with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 1

Going ahead to step 3:
When dividing 0 by 1, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 720.0
Subtract 0 from 0 to get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 1

Let's proceed to step 4:
When dividing 3 by 1, we get 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 7203.0
If we subtract 3 from 3, we get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 1

Going ahead to step 5:
1 can be fit into 5 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 72035.0
If we subtract 5 from 5, we get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 1

Advancing to step 6:
1 can be fit into 9 9 times, resulting in a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 720359.0
If we subtract 9 from 9, 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.

Advancing to step 7:
1 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 720359.0
Deduct 0 from 0 and we're left with 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:
0 divided by 1 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 720359.0
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 720359.0 with a remaining 0.0.
