We divide 763617 by 2
The aim is to understand the frequency of 2 in 763617.

Advancing to step 1:
7 divided by 2 is 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 6 from 7 and we're left with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 2

Moving on to step 2:
When dividing 16 by 2, we get 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 38.0
If we take 16 away from 16, we end up with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 2

Let's proceed to step 3:
2 can be fit into 3 1 times, resulting in a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 381.0
Deduct 2 from 3 and we're left with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 2

Let's proceed to step 4:
2 goes into 16 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 3818.0
If we subtract 16 from 16, we get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 2

Step 5:
If we divide 1 by 2, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 38180.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 2

Let's proceed to step 6:
When dividing 17 by 2, we get 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 381808.0
If we take 16 away from 17, we end up 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.

Moving 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: 381808.5
Subtract 10 from 10 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 8:
When dividing 0 by 2, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 381808.5
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.

Advancing to step 9:
2 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 381808.5
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.

The final result is 381808.5 with a remainder of 0.0.
