We divide 815192 by 2
The aim is to understand the frequency of 2 in 815192.

Advancing to step 1:
When dividing 8 by 2, we get 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 8 from 8 and we're left with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 2

On to step 2:
2 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
If we subtract 0 from 1, we get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 2

Let's proceed to step 3:
2 goes into 15 7 times with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 407.0
Subtracting 14 from 15 leaves us with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 2

Moving on to step 4:
11 divided by 2 is 5 with a remainder of 1.
The next digit of our result is 5. 
Result so far: 4075.0
If we subtract 10 from 11, we get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 2

Let's proceed to step 5:
The number 2 fits into 19 9 times, leaving a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 40759.0
Deduct 18 from 19 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 2

On to step 6:
2 goes into 12 6 times with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 407596.0
Deduct 12 from 12 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.

Moving on to step 7:
2 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 407596.0
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.

Moving on to step 8:
2 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 407596.0
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.

Our division results in 407596.0 with a remaining 0.0.
