We're dividing 685073 by 2 
The aim is to understand the frequency of 2 in 685073.

Going ahead to step 1:
6 divided by 2 is 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 6 from 6 to get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 2

Let's proceed to step 2:
When dividing 8 by 2, we get 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 34.0
If we take 8 away from 8, we end up with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 2

Let's proceed to step 3:
The number 2 fits into 5 2 times, leaving a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 342.0
Subtract 4 from 5 to get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 2

Step 4:
If we divide 10 by 2, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 3425.0
Deduct 10 from 10 and we're left with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 2

Step 5:
2 goes into 7 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 34253.0
If we take 6 away from 7, we end up with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 2

Advancing to step 6:
If we divide 13 by 2, we get 6 and a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 342536.0
If we subtract 12 from 13, we get 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.
Use 5 as the next digit of our solution. 
Result so far: 342536.5
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.

On to step 8:
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: 342536.5
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.

Step 9:
0 divided by 2 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 342536.5
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.

Our division results in 342536.5 with a remaining 0.0.
