We look at the division of 137607 by 2 
The aim is to understand the frequency of 2 in 137607.

Let's proceed to step 1:
The number 2 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 2

On to step 2:
13 divided by 2 is 6 with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 12 away from 13, we end up with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 2

Let's proceed to step 3:
When dividing 17 by 2, we get 8 with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 68.0
Subtract 16 from 17 to get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 2

On to step 4:
2 goes into 16 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 688.0
If we take 16 away from 16, we end up with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 2

Step 5:
If we divide 0 by 2, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6880.0
If we subtract 0 from 0, we get 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 2

Let's proceed to step 6:
2 can be fit into 7 3 times, resulting in a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 68803.0
Subtracting 6 from 7 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.

On to step 7:
If we divide 10 by 2, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 68803.5
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.

Moving on to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 68803.5
Subtract 0 from 0 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.

Let's proceed to step 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 68803.5
Subtract 0 from 0 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.

Our division results in 68803.5 with a remaining 0.0.
