722280 ÷ 1 
The aim is to understand the frequency of 1 in 722280.

Going ahead to step 1:
7 divided by 1 is 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 7 from 7 and we're left with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 1

Let's proceed to step 2:
2 divided by 1 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 72.0
Deduct 2 from 2 and we're left with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 1

Advancing to step 3:
When dividing 2 by 1, we get 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 722.0
The remainder is 0 after subtracting 2 from 2.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 1

Moving on to step 4:
The number 1 fits into 2 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 7222.0
If we take 2 away from 2, we end up with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

Going ahead to step 5:
1 can be fit into 8 8 times, resulting in a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 72228.0
If we take 8 away from 8, we end up with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 1

Step 6:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 722280.0
If we take 0 away from 0, we end up 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.

Going ahead to step 7:
0 divided by 1 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 722280.0
If we take 0 away from 0, we end up 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.

Moving on to step 8:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 722280.0
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.

Our division results in 722280.0 with a remaining 0.0.
