Let's divide 180923 by 25
The aim is to understand the frequency of 25 in 180923.

On to step 1:
If we divide 1 by 25, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 25

Advancing to step 2:
25 can be fit into 18 0 times, resulting in a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 25

Advancing to step 3:
When dividing 180 by 25, we get 7 with a remainder of 5.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 175 from 180 leaves us with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 25

Going ahead to step 4:
59 divided by 25 is 2 with a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
Deduct 50 from 59 and we're left with 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 25

Moving on to step 5:
25 goes into 92 3 times with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 723.0
Deduct 75 from 92 and we're left with 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 25

Step 6:
25 can be fit into 173 6 times, resulting in a remainder of 23.
Put 6 as the next digit of the answer. 
Result so far: 7236.0
If we subtract 150 from 173, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 7:
When dividing 230 by 25, we get 9 with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 7236.9
Deduct 225 from 230 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
If we divide 50 by 25, we get 2 and a remainder of 0.
The next digit of our result is 2. 
Result so far: 7236.92
Subtract 50 from 50 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.

Advancing to step 9:
When dividing 0 by 25, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 7236.92
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 10:
The number 25 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 7236.92
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.

After the division, we end up with 7236.92 and a remainder of 0.0.
