68187421 divided by 2 
The aim is to understand the frequency of 2 in 68187421.

Moving on to step 1:
2 goes into 6 3 times with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 6 away from 6, we end up with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 2

Let's proceed to step 2:
2 can be fit into 8 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 34.0
If we subtract 8 from 8, we get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 2

Advancing to step 3:
2 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 340.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 2

Step 4:
2 goes into 18 9 times with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 3409.0
If we take 18 away from 18, we end up with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 2

Let's proceed to step 5:
2 can be fit into 7 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 34093.0
Subtract 6 from 7 to get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 2

Going ahead to step 6:
When dividing 14 by 2, we get 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 340937.0
Deduct 14 from 14 and we're left with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 2

Going ahead to step 7:
2 goes into 2 1 times with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 3409371.0
If we take 2 away from 2, we end up with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 2

Advancing to step 8:
2 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 34093710.0
The remainder is 1 after subtracting 0 from 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
2 can be fit into 10 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 34093710.5
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 10:
0 divided by 2 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 34093710.5
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 11:
When dividing 0 by 2, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 34093710.5
The remainder is 0 after subtracting 0 from 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 34093710.5 with a remaining 0.0.
