We're dividing 128732 by 1 
The aim is to understand the frequency of 1 in 128732.

Step 1:
1 goes into 1 1 times with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 1 from 1, we get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 1

Going ahead to step 2:
If we divide 2 by 1, we get 2 and a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 2 from 2 to get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

Advancing to step 3:
1 goes into 8 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 128.0
If we subtract 8 from 8, we get 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: 1287.0
Subtract 7 from 7 to get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 1

Let's proceed to step 5:
The number 1 fits into 3 3 times, leaving a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 12873.0
The remainder is 0 after subtracting 3 from 3.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 1

Let's proceed to step 6:
The number 1 fits into 2 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 128732.0
Subtract 2 from 2 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.

Moving on to step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 128732.0
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.

Advancing to step 8:
0 divided by 1 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 128732.0
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.

The final outcome is 128732.0, with a leftover of 0.0.
