We're dividing 225518 by 2 
The aim is to understand the frequency of 2 in 225518.

On to step 1:
2 goes into 2 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 2 from 2, we get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 2

Let's proceed to step 2:
The number 2 fits into 2 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 2 away from 2, we end up with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 2

Advancing to step 3:
2 can be fit into 5 2 times, resulting in a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 112.0
If we subtract 4 from 5, we get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 2

Advancing to step 4:
2 goes into 15 7 times with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 1127.0
If we take 14 away from 15, we end up with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 2

On to step 5:
2 can be fit into 11 5 times, resulting in a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 11275.0
Subtracting 10 from 11 leaves us with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 2

Advancing to step 6:
2 goes into 18 9 times with a remainder of 0.
The next digit of our result is 9. 
Result so far: 112759.0
Deduct 18 from 18 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 7:
2 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 112759.0
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.

Going ahead to step 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 112759.0
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.

After the division, we end up with 112759.0 and a remainder of 0.0.
