We divide 859716 by 1
The aim is to understand the frequency of 1 in 859716.

Going ahead to step 1:
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: 8.0
Deduct 8 from 8 and we're left with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 1

Step 2:
5 divided by 1 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 85.0
If we subtract 5 from 5, we get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 1

On to step 3:
9 divided by 1 is 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 859.0
If we take 9 away from 9, we end up with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 1

Step 4:
1 goes into 7 7 times with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 8597.0
If we take 7 away from 7, we end up with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 1

Step 5:
1 can be fit into 1 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 85971.0
If we take 1 away from 1, we end up with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 1

Moving on to step 6:
If we divide 6 by 1, we get 6 and a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 859716.0
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.
Write down 0 as next digit of the result. 
Result so far: 859716.0
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.

Step 8:
1 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 859716.0
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.

After the division, we end up with 859716.0 and a remainder of 0.0.
