We're dividing 7981903 by 2 
The aim is to understand the frequency of 2 in 7981903.

Advancing to step 1:
If we divide 7 by 2, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 1 after subtracting 6 from 7.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 2

Going ahead to step 2:
2 goes into 19 9 times with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 39.0
Subtract 18 from 19 to get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 2

Let's proceed to step 3:
If we divide 18 by 2, we get 9 and a remainder of 0.
The next digit of our result is 9. 
Result so far: 399.0
The remainder is 0 after subtracting 18 from 18.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 2

Step 4:
The number 2 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 3990.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 2

Let's proceed to step 5:
When dividing 19 by 2, we get 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 39909.0
If we subtract 18 from 19, we get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 2

Moving on to step 6:
10 divided by 2 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 399095.0
If we take 10 away from 10, we end up with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 2

Let's proceed to step 7:
When dividing 3 by 2, we get 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 3990951.0
Subtracting 2 from 3 leaves us 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.

Advancing to step 8:
If we divide 10 by 2, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 3990951.5
If we subtract 10 from 10, 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.

Let's proceed to step 9:
If we divide 0 by 2, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3990951.5
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.

Moving on to step 10:
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: 3990951.5
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.

The final result is 3990951.5 with a remainder of 0.0.
