We look at the division of 687772 by 2 
The aim is to understand the frequency of 2 in 687772.

Advancing to step 1:
2 goes into 6 3 times with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 6 away from 6, we end up with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 2

Step 2:
The number 2 fits into 8 4 times, leaving a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
Subtract 8 from 8 to get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 2

Advancing to step 3:
The number 2 fits into 7 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 343.0
If we take 6 away from 7, we end up with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 2

Step 4:
17 divided by 2 is 8 with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 3438.0
If we subtract 16 from 17, we get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 2

Step 5:
When dividing 17 by 2, we get 8 with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 34388.0
Subtracting 16 from 17 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 2

Going ahead to step 6:
2 goes into 12 6 times with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 343886.0
If we subtract 12 from 12, 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.

Going ahead to step 7:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 343886.0
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.

Going ahead to step 8:
2 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 343886.0
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.

The final outcome is 343886.0, with a leftover of 0.0.
