We look at the division of 705628 by 45 
The aim is to understand the frequency of 45 in 705628.

Let's proceed to step 1:
45 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 45

Step 2:
When dividing 70 by 45, we get 1 with a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 45 from 70 leaves us with 25.
Fetch the next digit (5) from the dividend, attach it to 25 and continue: 255 / 45

Let's proceed to step 3:
255 divided by 45 is 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 15.0
The remainder is 30 after subtracting 225 from 255.
Bring next digit (6) of the dividend behind the 30 and repeat the process: 306 / 45

Going ahead to step 4:
45 goes into 306 6 times with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 156.0
The remainder is 36 after subtracting 270 from 306.
Bring next digit (2) of the dividend behind the 36 and repeat the process: 362 / 45

Moving on to step 5:
45 goes into 362 8 times with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 1568.0
If we subtract 360 from 362, we get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 45

Advancing to step 6:
28 divided by 45 is 0 with a remainder of 28.
The next digit of our result is 0. 
Result so far: 15680.0
Subtracting 0 from 28 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 7:
45 goes into 280 6 times with a remainder of 10.
The next digit of our result is 6. 
Result so far: 15680.6
If we take 270 away from 280, 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.

Step 8:
100 divided by 45 is 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 15680.62
Subtracting 90 from 100 leaves us 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.

On to step 9:
100 divided by 45 is 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 15680.622
Subtract 90 from 100 to 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.

The final result is 15680.622 with a remainder of 0.001.
