438902 ÷ 2 
The aim is to understand the frequency of 2 in 438902.

On to step 1:
When dividing 4 by 2, we get 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 0 after subtracting 4 from 4.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 2

On to step 2:
2 goes into 3 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we take 2 away from 3, we end up with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 2

Let's proceed to step 3:
The number 2 fits into 18 9 times, leaving a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 219.0
If we take 18 away from 18, we end up with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 2

On to step 4:
9 divided by 2 is 4 with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 2194.0
The remainder is 1 after subtracting 8 from 9.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 2

Going ahead to step 5:
10 divided by 2 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 21945.0
If we take 10 away from 10, we end up with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 2

Moving on to step 6:
The number 2 fits into 2 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 219451.0
Subtract 2 from 2 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.

On to step 7:
0 divided by 2 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 219451.0
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.

Let's proceed to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 219451.0
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.

The final result is 219451.0 with a remainder of 0.0.
