We divide 562565 by 45
The aim is to understand the frequency of 45 in 562565.

Going ahead to step 1:
5 divided by 45 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 45

Moving on to step 2:
If we divide 56 by 45, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 45 from 56 leaves us with 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 45

On to step 3:
If we divide 112 by 45, we get 2 and a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 90 from 112 to get 22.
Include the next digit (5) from the dividend after 22, then repeat: 225 / 45

Step 4:
If we divide 225 by 45, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 125.0
Deduct 225 from 225 and we're left with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 45

Going ahead to step 5:
6 divided by 45 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 1250.0
Subtract 0 from 6 to get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 45

On to step 6:
The number 45 fits into 65 1 times, leaving a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 12501.0
The remainder is 20 after subtracting 45 from 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
The number 45 fits into 200 4 times, leaving a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 12501.4
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
When dividing 200 by 45, we get 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 12501.44
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 12501.44, with a leftover of 0.02.
