We look at the division of 131297 by 1 
The aim is to understand the frequency of 1 in 131297.

Advancing to step 1:
If we divide 1 by 1, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 1 from 1 to get 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 1

On to step 2:
When dividing 3 by 1, we get 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 3 from 3 leaves us with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 1

Let's proceed to step 3:
When dividing 1 by 1, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 131.0
Subtracting 1 from 1 leaves us with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 1

On to step 4:
2 divided by 1 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 1312.0
The remainder is 0 after subtracting 2 from 2.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 1

Moving on to step 5:
1 goes into 9 9 times with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 13129.0
Subtracting 9 from 9 leaves us with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 1

On to step 6:
When dividing 7 by 1, we get 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 131297.0
The remainder is 0 after subtracting 7 from 7.
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:
When dividing 0 by 1, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 131297.0
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 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: 131297.0
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.

In conclusion, the division gives 131297.0 with a balance of 0.0.
