757590 divided by 1 
The aim is to understand the frequency of 1 in 757590.

On to step 1:
The number 1 fits into 7 7 times, leaving a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 7 from 7, we get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 1

Going ahead to step 2:
When dividing 5 by 1, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
Deduct 5 from 5 and we're left with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 1

On to step 3:
7 divided by 1 is 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 757.0
If we take 7 away from 7, we end up with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 1

Advancing to step 4:
When dividing 5 by 1, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 7575.0
Subtracting 5 from 5 leaves us with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 1

Step 5:
The number 1 fits into 9 9 times, leaving a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 75759.0
Subtracting 9 from 9 leaves us with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 1

Let's proceed to step 6:
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: 757590.0
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.

Let's proceed to step 7:
0 divided by 1 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 757590.0
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.

On to step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 757590.0
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.

In conclusion, the division gives 757590.0 with a balance of 0.0.
