We're dividing 84030 by 2 
The aim is to understand the frequency of 2 in 84030.

Going ahead to step 1:
2 can be fit into 8 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 0 after subtracting 8 from 8.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 2

Let's proceed to step 2:
2 can be fit into 4 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 42.0
The remainder is 0 after subtracting 4 from 4.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 2

Step 3:
0 divided by 2 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 420.0
Subtracting 0 from 0 leaves us with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 2

Going ahead to step 4:
If we divide 3 by 2, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 4201.0
If we subtract 2 from 3, we get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 2

Going ahead to step 5:
When dividing 10 by 2, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 42015.0
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 6:
When dividing 0 by 2, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 42015.0
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.

Let's proceed to step 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 42015.0
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.

The quotient of the division is 42015.0, and the remainder is 0.0.
