702255 ÷ 1 
The aim is to understand the frequency of 1 in 702255.

Moving on to step 1:
1 goes into 7 7 times with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 7 from 7 to get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 1

On to step 2:
If we divide 0 by 1, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
If we subtract 0 from 0, we get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 1

Step 3:
When dividing 2 by 1, we get 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 702.0
If we take 2 away from 2, we end up with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 1

Advancing to step 4:
1 goes into 2 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 7022.0
If we subtract 2 from 2, we get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 1

On to step 5:
1 goes into 5 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 70225.0
The remainder is 0 after subtracting 5 from 5.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 1

Going ahead to step 6:
1 goes into 5 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 702255.0
Subtracting 5 from 5 leaves us 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.

Step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 702255.0
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.

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: 702255.0
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.

The final outcome is 702255.0, with a leftover of 0.0.
