We look at the division of 868312 by 1 
The aim is to understand the frequency of 1 in 868312.

Let's proceed to step 1:
1 can be fit into 8 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 8 from 8 leaves us with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 1

On to step 2:
When dividing 6 by 1, we get 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
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

Advancing to step 3:
8 divided by 1 is 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 868.0
Subtract 8 from 8 to get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 1

Step 4:
If we divide 3 by 1, we get 3 and a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 8683.0
Subtract 3 from 3 to get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 1

Step 5:
1 can be fit into 1 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 86831.0
The remainder is 0 after subtracting 1 from 1.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 1

Advancing to step 6:
1 can be fit into 2 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 868312.0
Deduct 2 from 2 and we're left 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.

Let's proceed to step 7:
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: 868312.0
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 8:
0 divided by 1 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 868312.0
Deduct 0 from 0 and we're left 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 result is 868312.0 with a remainder of 0.0.
