We look at the division of 402760 by 45 
The aim is to understand the frequency of 45 in 402760.

Going ahead to step 1:
45 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 45

Moving on to step 2:
45 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Fetch the next digit (2) from the dividend, attach it to 40 and continue: 402 / 45

Step 3:
When dividing 402 by 45, we get 8 with a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 360 from 402, we get 42.
Bring next digit (7) of the dividend behind the 42 and repeat the process: 427 / 45

Moving on to step 4:
If we divide 427 by 45, we get 9 and a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 89.0
Subtract 405 from 427 to get 22.
Take the next digit (6) from the dividend and append it to 22, then repeat: 226 / 45

Going ahead to step 5:
45 can be fit into 226 5 times, resulting in a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 895.0
If we subtract 225 from 226, we get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 45

Going ahead to step 6:
45 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 8950.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
The number 45 fits into 100 2 times, leaving a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 8950.2
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
45 goes into 100 2 times with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 8950.22
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 8950.22 and a remainder of 0.01.
