Let's divide 544521 by 2
The aim is to understand the frequency of 2 in 544521.

Going ahead to step 1:
5 divided by 2 is 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 4 from 5 leaves us with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 2

On to step 2:
2 can be fit into 14 7 times, resulting in a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 27.0
Deduct 14 from 14 and we're left with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 2

Let's proceed to step 3:
If we divide 4 by 2, we get 2 and a remainder of 0.
The next digit of our result is 2. 
Result so far: 272.0
Subtracting 4 from 4 leaves us with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 2

Moving on to step 4:
When dividing 5 by 2, we get 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2722.0
If we take 4 away from 5, we end up with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 2

Advancing to step 5:
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: 27226.0
Subtract 12 from 12 to get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 2

Going ahead to step 6:
2 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 272260.0
If we take 0 away from 1, we end up 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.

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: 272260.5
Subtract 10 from 10 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.

Going ahead to step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 272260.5
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.

Going ahead to step 9:
2 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 272260.5
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.

Our division results in 272260.5 with a remaining 0.0.
