We're dividing 178004 by 45 
The aim is to understand the frequency of 45 in 178004.

Going ahead to step 1:
45 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 45

Moving on to step 2:
17 divided by 45 is 0 with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 45

Moving on to step 3:
The number 45 fits into 178 3 times, leaving a remainder of 43.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 43 after subtracting 135 from 178.
Append the next digit (0) from the dividend to 43 and continue with: 430 / 45

Step 4:
When dividing 430 by 45, we get 9 with a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Subtracting 405 from 430 leaves us with 25.
Fetch the next digit (0) from the dividend, attach it to 25 and continue: 250 / 45

On to step 5:
The number 45 fits into 250 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 395.0
If we take 225 away from 250, we end up with 25.
Include the next digit (4) from the dividend after 25, then repeat: 254 / 45

On to step 6:
The number 45 fits into 254 5 times, leaving a remainder of 29.
The next digit of our result is 5. 
Result so far: 3955.0
Deduct 225 from 254 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
The number 45 fits into 290 6 times, leaving a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 3955.6
If we take 270 away from 290, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
If we divide 200 by 45, we get 4 and a remainder of 20.
The next digit of our result is 4. 
Result so far: 3955.64
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
When dividing 200 by 45, we get 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 3955.644
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 3955.644 with a remainder of 0.002.
