We look at the division of 177459 by 45 
The aim is to understand the frequency of 45 in 177459.

Let's proceed to step 1:
If we divide 1 by 45, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 45

Moving on to step 2:
17 divided by 45 is 0 with a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 45

Step 3:
45 can be fit into 177 3 times, resulting in a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 135 from 177, we get 42.
Include the next digit (4) from the dividend after 42, then repeat: 424 / 45

On to step 4:
45 can be fit into 424 9 times, resulting in a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
If we take 405 away from 424, we end up with 19.
Grab the next digit (5) from the dividend, add it to 19, then carry on: 195 / 45

Moving on to step 5:
195 divided by 45 is 4 with a remainder of 15.
Record the quotient 4 as the next digit in the result. 
Result so far: 394.0
If we subtract 180 from 195, we get 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 45

Moving on to step 6:
45 can be fit into 159 3 times, resulting in a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 3943.0
Deduct 135 from 159 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 7:
When dividing 240 by 45, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 3943.5
If we subtract 225 from 240, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
When dividing 150 by 45, we get 3 with a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 3943.53
The remainder is 15 after subtracting 135 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
45 goes into 150 3 times with a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 3943.533
If we subtract 135 from 150, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 3943.533 with a remainder of 0.0015.
