We look at the division of 468822 by 45 
The aim is to understand the frequency of 45 in 468822.

Advancing to step 1:
When dividing 4 by 45, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 45

Moving on to step 2:
The number 45 fits into 46 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 45 from 46 to get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 45

Advancing to step 3:
18 divided by 45 is 0 with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 18, we get 18.
Include the next digit (8) from the dividend after 18, then repeat: 188 / 45

Moving on to step 4:
45 can be fit into 188 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
Subtracting 180 from 188 leaves us with 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 45

On to step 5:
When dividing 82 by 45, we get 1 with a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 1041.0
Subtract 45 from 82 to get 37.
Take the next digit (2) from the dividend and append it to 37, then repeat: 372 / 45

Advancing to step 6:
45 can be fit into 372 8 times, resulting in a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 10418.0
Subtracting 360 from 372 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
45 goes into 120 2 times with a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 10418.2
If we take 90 away from 120, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
45 goes into 300 6 times with a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 10418.26
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
300 divided by 45 is 6 with a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 10418.266
If we subtract 270 from 300, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 10418.266, with a leftover of 0.003.
