Let's divide 250543 by 2
The aim is to understand the frequency of 2 in 250543.

Step 1:
The number 2 fits into 2 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
If we take 2 away from 2, we end up with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 2

On to step 2:
The number 2 fits into 5 2 times, leaving a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 4 from 5 to get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 2

Let's proceed to step 3:
10 divided by 2 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 125.0
The remainder is 0 after subtracting 10 from 10.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 2

Going ahead to step 4:
When dividing 5 by 2, we get 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 1252.0
Deduct 4 from 5 and we're left with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 2

Let's proceed to step 5:
The number 2 fits into 14 7 times, leaving a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 12527.0
If we subtract 14 from 14, we get 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 2

Step 6:
When dividing 3 by 2, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 125271.0
Deduct 2 from 3 and we're left 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:
10 divided by 2 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 125271.5
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.

Let's proceed to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 125271.5
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.

Step 9:
When dividing 0 by 2, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 125271.5
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 125271.5 and a remainder of 0.0.
