We divide 149220 by 2
The aim is to understand the frequency of 2 in 149220.

Moving on to step 1:
If we divide 1 by 2, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 2

Moving on to step 2:
The number 2 fits into 14 7 times, leaving a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 0 after subtracting 14 from 14.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 2

Let's proceed to step 3:
When dividing 9 by 2, we get 4 with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
The remainder is 1 after subtracting 8 from 9.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 2

Going ahead to step 4:
12 divided by 2 is 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 746.0
If we subtract 12 from 12, we get 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 2

Moving on to step 5:
When dividing 2 by 2, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 7461.0
Deduct 2 from 2 and we're left with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 2

Let's proceed to step 6:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 74610.0
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.

On to step 7:
0 divided by 2 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 74610.0
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.

Going ahead to step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 74610.0
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.

In conclusion, the division gives 74610.0 with a balance of 0.0.
