We look at the division of 426698 by 2 
The aim is to understand the frequency of 2 in 426698.

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
Subtracting 4 from 4 leaves us with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 2

Going ahead to step 2:
When dividing 2 by 2, we get 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
The remainder is 0 after subtracting 2 from 2.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 2

Step 3:
6 divided by 2 is 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 213.0
Subtract 6 from 6 to get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 2

Advancing to step 4:
If we divide 6 by 2, we get 3 and a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 2133.0
Deduct 6 from 6 and we're left with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 2

Advancing to step 5:
If we divide 9 by 2, we get 4 and a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 21334.0
Deduct 8 from 9 and we're left with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 2

Let's proceed to step 6:
The number 2 fits into 18 9 times, leaving a remainder of 0.
The next digit of our result is 9. 
Result so far: 213349.0
Subtract 18 from 18 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.

Advancing to step 7:
2 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 213349.0
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.

Going ahead to step 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 213349.0
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.

After the division, we end up with 213349.0 and a remainder of 0.0.
