Let's divide 154356 by 2
The aim is to understand the frequency of 2 in 154356.

Going ahead to step 1:
The number 2 fits into 1 0 times, leaving 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 (5) from the dividend, add it to 1, then carry on: 15 / 2

Step 2:
2 goes into 15 7 times with a remainder of 1.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 14 from 15, we get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 2

Advancing to step 3:
If we divide 14 by 2, we get 7 and a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 77.0
If we subtract 14 from 14, we get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 2

Let's proceed to step 4:
2 can be fit into 3 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 771.0
The remainder is 1 after subtracting 2 from 3.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 2

Moving on to step 5:
15 divided by 2 is 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 7717.0
If we subtract 14 from 15, we get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 2

On to step 6:
If we divide 16 by 2, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 77178.0
Subtracting 16 from 16 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.

Advancing 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: 77178.0
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.

Going ahead to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 77178.0
Subtract 0 from 0 to 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.

The final outcome is 77178.0, with a leftover of 0.0.
