We look at the division of 557131 by 2 
The aim is to understand the frequency of 2 in 557131.

Let's proceed to step 1:
5 divided by 2 is 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 1 after subtracting 4 from 5.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 2

Moving on to step 2:
The number 2 fits into 15 7 times, leaving a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 27.0
If we subtract 14 from 15, we get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 2

Step 3:
The number 2 fits into 17 8 times, leaving a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 278.0
The remainder is 1 after subtracting 16 from 17.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 2

On to step 4:
If we divide 11 by 2, we get 5 and a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 2785.0
Subtracting 10 from 11 leaves us with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 2

Moving on to step 5:
2 can be fit into 13 6 times, resulting in a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 27856.0
Deduct 12 from 13 and we're left with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 2

Let's proceed to step 6:
2 goes into 11 5 times with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 278565.0
Subtracting 10 from 11 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 278565.5
The remainder is 0 after subtracting 10 from 10.
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:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 278565.5
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 9:
0 divided by 2 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 278565.5
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.

In conclusion, the division gives 278565.5 with a balance of 0.0.
