We divide 586739 by 1
The aim is to understand the frequency of 1 in 586739.

Moving on to step 1:
5 divided by 1 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 5 from 5, we get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 1

Let's proceed to step 2:
When dividing 8 by 1, we get 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 58.0
The remainder is 0 after subtracting 8 from 8.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 1

Advancing to step 3:
The number 1 fits into 6 6 times, leaving a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 586.0
If we take 6 away from 6, we end up with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 1

Let's proceed to step 4:
1 can be fit into 7 7 times, resulting in a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 5867.0
Subtract 7 from 7 to get 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 1

On to step 5:
If we divide 3 by 1, we get 3 and a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 58673.0
Subtracting 3 from 3 leaves us with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 1

On to step 6:
9 divided by 1 is 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 586739.0
If we take 9 away from 9, 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.

Advancing to step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 586739.0
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.

On to step 8:
1 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 586739.0
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.

The final result is 586739.0 with a remainder of 0.0.
