We divide 107309 by 1
The aim is to understand the frequency of 1 in 107309.

Step 1:
1 divided by 1 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 0 after subtracting 1 from 1.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 1

Step 2:
1 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 0 after subtracting 0 from 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 1

On to step 3:
1 goes into 7 7 times with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
If we subtract 7 from 7, we get 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 1

Step 4:
1 goes into 3 3 times with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 1073.0
If we take 3 away from 3, we end up with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 1

On to step 5:
When dividing 0 by 1, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10730.0
Subtract 0 from 0 to get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 1

Let's proceed to step 6:
1 can be fit into 9 9 times, resulting in a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 107309.0
Subtract 9 from 9 to 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.

On to step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 107309.0
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.

Going ahead to step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 107309.0
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 107309.0 with a remainder of 0.0.
