We divide 525501 by 2
The aim is to understand the frequency of 2 in 525501.

Step 1:
2 goes into 5 2 times with a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 4 from 5, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 2

Advancing to step 2:
2 can be fit into 12 6 times, resulting in a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
If we take 12 away from 12, we end up with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 2

Advancing to step 3:
2 can be fit into 5 2 times, resulting in a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 262.0
Deduct 4 from 5 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 2

Going ahead to step 4:
The number 2 fits into 15 7 times, leaving a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 2627.0
Deduct 14 from 15 and we're left with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 2

Let's proceed to step 5:
2 goes into 10 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 26275.0
The remainder is 0 after subtracting 10 from 10.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 2

Going ahead to step 6:
2 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 262750.0
Subtracting 0 from 1 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.

Let's proceed to step 7:
If we divide 10 by 2, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 262750.5
If we subtract 10 from 10, 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.

Going ahead to step 8:
2 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 262750.5
Subtracting 0 from 0 leaves us 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 9:
0 divided by 2 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 262750.5
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.

In conclusion, the division gives 262750.5 with a balance of 0.0.
