809887 ÷ 1 
The aim is to understand the frequency of 1 in 809887.

Step 1:
1 goes into 8 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 8 from 8, we get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

On to step 2:
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: 80.0
If we take 0 away from 0, we end up with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 1

Let's proceed to step 3:
1 can be fit into 9 9 times, resulting in a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 809.0
The remainder is 0 after subtracting 9 from 9.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 1

Moving on to step 4:
The number 1 fits into 8 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 8098.0
Deduct 8 from 8 and we're left with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

Moving on to step 5:
1 goes into 8 8 times with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 80988.0
If we take 8 away from 8, we end up with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 1

On to step 6:
When dividing 7 by 1, we get 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 809887.0
If we subtract 7 from 7, 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 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 809887.0
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.
Put 0 as the next digit of the answer. 
Result so far: 809887.0
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.

The final result is 809887.0 with a remainder of 0.0.
