We look at the division of 272687 by 45 
The aim is to understand the frequency of 45 in 272687.

Going ahead to step 1:
45 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 45

Step 2:
The number 45 fits into 27 0 times, leaving a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 27, we get 27.
Grab the next digit (2) from the dividend, add it to 27, then carry on: 272 / 45

Let's proceed to step 3:
The number 45 fits into 272 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 2 after subtracting 270 from 272.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 45

On to step 4:
45 can be fit into 26 0 times, resulting in a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 60.0
Subtract 0 from 26 to get 26.
Include the next digit (8) from the dividend after 26, then repeat: 268 / 45

Step 5:
If we divide 268 by 45, we get 5 and a remainder of 43.
The next digit of our result is 5. 
Result so far: 605.0
The remainder is 43 after subtracting 225 from 268.
Fetch the next digit (7) from the dividend, attach it to 43 and continue: 437 / 45

On to step 6:
437 divided by 45 is 9 with a remainder of 32.
Record the quotient 9 as the next digit in the result. 
Result so far: 6059.0
If we take 405 away from 437, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 7:
45 can be fit into 320 7 times, resulting in a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 6059.7
If we subtract 315 from 320, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
If we divide 50 by 45, we get 1 and a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 6059.71
Subtracting 45 from 50 leaves us 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.

Advancing to step 9:
When dividing 50 by 45, we get 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 6059.711
Subtracting 45 from 50 leaves us 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.

The final result is 6059.711 with a remainder of 0.0005.
