865956 ÷ 1 
The aim is to understand the frequency of 1 in 865956.

Step 1:
1 can be fit into 8 8 times, resulting in a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 8 from 8 to get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 1

Step 2:
The number 1 fits into 6 6 times, leaving a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
Deduct 6 from 6 and we're left with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 1

Going ahead to step 3:
If we divide 5 by 1, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 865.0
Subtract 5 from 5 to get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 1

Let's proceed to step 4:
9 divided by 1 is 9 with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 8659.0
If we take 9 away from 9, we end up with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 1

Going ahead to step 5:
If we divide 5 by 1, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 86595.0
If we subtract 5 from 5, we get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 1

Step 6:
1 goes into 6 6 times with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 865956.0
Subtracting 6 from 6 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.

Moving on to step 7:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 865956.0
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.

Let's proceed to step 8:
1 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 865956.0
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.

The final result is 865956.0 with a remainder of 0.0.
