868398 ÷ 1 
The aim is to understand the frequency of 1 in 868398.

Step 1:
When dividing 8 by 1, we get 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 8 from 8, we get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 1

Let's proceed to step 2:
1 goes into 6 6 times with a remainder of 0.
The next digit of our result is 6. 
Result so far: 86.0
If we subtract 6 from 6, we get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 1

Step 3:
When dividing 8 by 1, we get 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 868.0
The remainder is 0 after subtracting 8 from 8.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 1

Let's proceed to step 4:
3 divided by 1 is 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 8683.0
If we subtract 3 from 3, we get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 1

Step 5:
If we divide 9 by 1, we get 9 and a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 86839.0
Deduct 9 from 9 and we're left with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 1

Moving on to step 6:
1 goes into 8 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 868398.0
Deduct 8 from 8 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.

On to step 7:
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: 868398.0
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.

Going ahead to step 8:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 868398.0
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 868398.0 with a remainder of 0.0.
