We're dividing 853688 by 2 
The aim is to understand the frequency of 2 in 853688.

On to step 1:
The number 2 fits into 8 4 times, leaving a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 8 from 8 leaves us with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 2

Going ahead to step 2:
2 goes into 5 2 times with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 42.0
Subtract 4 from 5 to get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 2

Let's proceed to step 3:
When dividing 13 by 2, we get 6 with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 426.0
If we take 12 away from 13, we end up with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 2

Moving on to step 4:
2 can be fit into 16 8 times, resulting in a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 4268.0
Subtracting 16 from 16 leaves us with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 2

Advancing to step 5:
2 can be fit into 8 4 times, resulting in a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 42684.0
Subtract 8 from 8 to get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 2

Let's proceed to step 6:
2 goes into 8 4 times with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 426844.0
If we take 8 away from 8, 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.

Moving on to step 7:
0 divided by 2 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 426844.0
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 8:
2 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 426844.0
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 outcome is 426844.0, with a leftover of 0.0.
