Let's divide 286615 by 2
The aim is to understand the frequency of 2 in 286615.

Advancing to step 1:
If we divide 2 by 2, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 2 away from 2, we end up with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 2

Going ahead to step 2:
When dividing 8 by 2, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 8 from 8 and we're left with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 2

Moving on to step 3:
When dividing 6 by 2, we get 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 143.0
If we subtract 6 from 6, we get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 2

Let's proceed to step 4:
6 divided by 2 is 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 1433.0
Subtract 6 from 6 to get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 2

Moving on to step 5:
2 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 14330.0
If we take 0 away from 1, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 2

Let's proceed to step 6:
If we divide 15 by 2, we get 7 and a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 143307.0
Subtract 14 from 15 to 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.
Write down 5 as next digit of the result. 
Result so far: 143307.5
If we take 10 away from 10, we end up 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.

Let's proceed to step 8:
0 divided by 2 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 143307.5
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.

Advancing to step 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 143307.5
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.

The final outcome is 143307.5, with a leftover of 0.0.
