19121185 ÷ 2 
The aim is to understand the frequency of 2 in 19121185.

Moving on to step 1:
If we divide 1 by 2, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 2

Moving on to step 2:
The number 2 fits into 19 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 18 from 19 to get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 2

Let's proceed to step 3:
2 goes into 11 5 times with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
Subtract 10 from 11 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 2

Let's proceed to step 4:
2 goes into 12 6 times with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 956.0
If we subtract 12 from 12, we get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 2

Moving on to step 5:
When dividing 1 by 2, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 9560.0
If we subtract 0 from 1, we get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 2

Step 6:
11 divided by 2 is 5 with a remainder of 1.
The next digit of our result is 5. 
Result so far: 95605.0
If we take 10 away from 11, we end up with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 2

Advancing to step 7:
2 goes into 18 9 times with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 956059.0
Subtract 18 from 18 to get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 2

Advancing to step 8:
5 divided by 2 is 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 9560592.0
Subtract 4 from 5 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
If we divide 10 by 2, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 9560592.5
Deduct 10 from 10 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.

Let's proceed to step 10:
If we divide 0 by 2, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 9560592.5
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.

Moving on to step 11:
2 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9560592.5
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.

After the division, we end up with 9560592.5 and a remainder of 0.0.
