We're dividing 186640 by 2 
The aim is to understand the frequency of 2 in 186640.

Moving on to step 1:
When dividing 1 by 2, we get 0 with 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 (8) from the dividend, add it to 1, then carry on: 18 / 2

On to step 2:
2 goes into 18 9 times with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 18 from 18 leaves us with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 2

Advancing to step 3:
The number 2 fits into 6 3 times, leaving a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
Subtract 6 from 6 to get 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 2

Advancing to step 4:
2 goes into 6 3 times with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 933.0
The remainder is 0 after subtracting 6 from 6.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 2

Let's proceed to step 5:
4 divided by 2 is 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 9332.0
The remainder is 0 after subtracting 4 from 4.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 2

Advancing to step 6:
If we divide 0 by 2, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 93320.0
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.

Moving on to step 7:
If we divide 0 by 2, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 93320.0
Subtracting 0 from 0 leaves us 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: 93320.0
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.

The final outcome is 93320.0, with a leftover of 0.0.
