We look at the division of 265928 by 45 
The aim is to understand the frequency of 45 in 265928.

On to step 1:
The number 45 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 45

Going ahead to step 2:
When dividing 26 by 45, we get 0 with a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 26 after subtracting 0 from 26.
Bring next digit (5) of the dividend behind the 26 and repeat the process: 265 / 45

Step 3:
When dividing 265 by 45, we get 5 with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 40 after subtracting 225 from 265.
Fetch the next digit (9) from the dividend, attach it to 40 and continue: 409 / 45

Moving on to step 4:
When dividing 409 by 45, we get 9 with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 59.0
If we take 405 away from 409, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 45

On to step 5:
42 divided by 45 is 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 590.0
Subtracting 0 from 42 leaves us with 42.
Fetch the next digit (8) from the dividend, attach it to 42 and continue: 428 / 45

Moving on to step 6:
If we divide 428 by 45, we get 9 and a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 5909.0
The remainder is 23 after subtracting 405 from 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
230 divided by 45 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 5909.5
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.

Advancing to step 8:
45 goes into 50 1 times with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 5909.51
If we take 45 away from 50, we end up 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.

On to step 9:
45 goes into 50 1 times with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 5909.511
If we subtract 45 from 50, 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.

The final result is 5909.511 with a remainder of 0.0005.
