We're dividing 122280 by 45 
The aim is to understand the frequency of 45 in 122280.

Moving on to step 1:
If we divide 1 by 45, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 45

Advancing to step 2:
12 divided by 45 is 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 45

Let's proceed to step 3:
When dividing 122 by 45, we get 2 with a remainder of 32.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 90 from 122 and we're left with 32.
Append the next digit (2) from the dividend to 32 and continue with: 322 / 45

Going ahead to step 4:
45 goes into 322 7 times with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 27.0
Subtracting 315 from 322 leaves us with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 45

Let's proceed to step 5:
78 divided by 45 is 1 with a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 271.0
Subtracting 45 from 78 leaves us with 33.
Append the next digit (0) from the dividend to 33 and continue with: 330 / 45

On to step 6:
330 divided by 45 is 7 with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 2717.0
Deduct 315 from 330 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
The number 45 fits into 150 3 times, leaving a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 2717.3
If we take 135 away from 150, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 8:
When dividing 150 by 45, we get 3 with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 2717.33
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 outcome is 2717.33, with a leftover of 0.015.
