12907888 divided by 1 
The aim is to understand the frequency of 1 in 12907888.

Let's proceed to 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
Subtract 1 from 1 to get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 1

Going ahead to step 2:
1 goes into 2 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 2 away from 2, we end up with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 1

Step 3:
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: 129.0
Subtract 9 from 9 to get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Step 4:
1 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1290.0
The remainder is 0 after subtracting 0 from 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 1

Moving on to step 5:
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: 12907.0
If we subtract 7 from 7, we get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

Moving on to step 6:
When dividing 8 by 1, we get 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 129078.0
If we take 8 away from 8, we end up with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

Step 7:
1 can be fit into 8 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 1290788.0
If we take 8 away from 8, we end up with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 1

On to step 8:
8 divided by 1 is 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 12907888.0
If we take 8 away from 8, 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.

Step 9:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12907888.0
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 10:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12907888.0
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.

In conclusion, the division gives 12907888.0 with a balance of 0.0.
