We're dividing 11989320 by 1 
The aim is to understand the frequency of 1 in 11989320.

Going ahead to step 1:
1 divided by 1 is 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 1 from 1 leaves us with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 1

Step 2:
When dividing 1 by 1, we get 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 1 from 1 leaves us with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 1

Step 3:
1 goes into 9 9 times with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 119.0
The remainder is 0 after subtracting 9 from 9.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 1

Advancing to step 4:
If we divide 8 by 1, we get 8 and a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 1198.0
Subtracting 8 from 8 leaves us with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 1

Advancing to step 5:
If we divide 9 by 1, we get 9 and a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 11989.0
Subtract 9 from 9 to get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 1

Let's proceed to step 6:
1 can be fit into 3 3 times, resulting in a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 119893.0
Subtracting 3 from 3 leaves us with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 1

Moving on to step 7:
1 can be fit into 2 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 1198932.0
Deduct 2 from 2 and we're left with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Advancing to step 8:
0 divided by 1 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11989320.0
Subtract 0 from 0 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.

Let's proceed to step 9:
1 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11989320.0
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.

Advancing to step 10:
1 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11989320.0
Subtract 0 from 0 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.

The final result is 11989320.0 with a remainder of 0.0.
