We look at the division of 470545 by 45 
The aim is to understand the frequency of 45 in 470545.

Step 1:
45 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 45

Step 2:
45 can be fit into 47 1 times, resulting in a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 45 from 47, we get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 45

Moving on to step 3:
20 divided by 45 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 20 to get 20.
Fetch the next digit (5) from the dividend, attach it to 20 and continue: 205 / 45

On to step 4:
When dividing 205 by 45, we get 4 with a remainder of 25.
Use 4 as the next digit of our solution. 
Result so far: 104.0
Deduct 180 from 205 and we're left with 25.
Append the next digit (4) from the dividend to 25 and continue with: 254 / 45

Moving on to step 5:
45 can be fit into 254 5 times, resulting in a remainder of 29.
Write down 5 as next digit of the result. 
Result so far: 1045.0
Subtract 225 from 254 to get 29.
Bring next digit (5) of the dividend behind the 29 and repeat the process: 295 / 45

Let's proceed to step 6:
45 can be fit into 295 6 times, resulting in a remainder of 25.
Use 6 as the next digit of our solution. 
Result so far: 10456.0
The remainder is 25 after subtracting 270 from 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 7:
45 goes into 250 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 10456.5
Subtracting 225 from 250 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 8:
When dividing 250 by 45, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 10456.55
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final result is 10456.55 with a remainder of 0.025.
