Let's divide 902291 by 2
The aim is to understand the frequency of 2 in 902291.

Advancing to step 1:
If we divide 9 by 2, we get 4 and a remainder of 1.
The next digit of our result is 4. 
Result so far: 4.0
If we take 8 away from 9, we end up with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 2

Moving on to step 2:
2 goes into 10 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Subtracting 10 from 10 leaves us with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 2

On to step 3:
The number 2 fits into 2 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 451.0
Subtract 2 from 2 to get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 2

Step 4:
2 divided by 2 is 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 4511.0
Subtract 2 from 2 to get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 2

Moving on to step 5:
When dividing 9 by 2, we get 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 45114.0
If we take 8 away from 9, we end up with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 2

Let's proceed to step 6:
When dividing 11 by 2, we get 5 with a remainder of 1.
The next digit of our result is 5. 
Result so far: 451145.0
Subtract 10 from 11 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 451145.5
If we take 10 away from 10, 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.

On to step 8:
0 divided by 2 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 451145.5
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.
The next digit of our result is 0. 
Result so far: 451145.5
Deduct 0 from 0 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.

Our division results in 451145.5 with a remaining 0.0.
