Let's divide 687728 by 1
The aim is to understand the frequency of 1 in 687728.

Going ahead to step 1:
If we divide 6 by 1, we get 6 and a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 6 from 6, we get 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 1

On to step 2:
8 divided by 1 is 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
Deduct 8 from 8 and we're left with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 1

Going ahead to step 3:
If we divide 7 by 1, we get 7 and a remainder of 0.
The next digit of our result is 7. 
Result so far: 687.0
If we take 7 away from 7, we end up with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 1

Step 4:
1 goes into 7 7 times with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 6877.0
If we subtract 7 from 7, we get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 1

Going ahead to step 5:
2 divided by 1 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 68772.0
If we take 2 away from 2, we end up with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 1

Advancing to step 6:
8 divided by 1 is 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 687728.0
Subtracting 8 from 8 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.

Advancing to step 7:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 687728.0
Subtracting 0 from 0 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.

On to step 8:
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: 687728.0
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 687728.0 with a balance of 0.0.
