578592 ÷ 2 
The aim is to understand the frequency of 2 in 578592.

Let's proceed to step 1:
The number 2 fits into 5 2 times, leaving a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 1 after subtracting 4 from 5.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 2

Moving on to step 2:
2 goes into 17 8 times with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Subtracting 16 from 17 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 2

Advancing to step 3:
The number 2 fits into 18 9 times, leaving a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 289.0
Subtracting 18 from 18 leaves us with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 2

Moving on to step 4:
If we divide 5 by 2, we get 2 and a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2892.0
Subtracting 4 from 5 leaves us with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 2

Step 5:
When dividing 19 by 2, we get 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 28929.0
Subtracting 18 from 19 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 2

Going ahead to step 6:
The number 2 fits into 12 6 times, leaving a remainder of 0.
The next digit of our result is 6. 
Result so far: 289296.0
The remainder is 0 after subtracting 12 from 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
0 divided by 2 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 289296.0
If we take 0 away from 0, 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.

Advancing to step 8:
When dividing 0 by 2, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 289296.0
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.

After the division, we end up with 289296.0 and a remainder of 0.0.
