We're dividing 24660145 by 45 
The aim is to understand the frequency of 45 in 24660145.

On to step 1:
When dividing 2 by 45, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 45

Moving on to step 2:
The number 45 fits into 24 0 times, leaving a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 24, we end up with 24.
Bring next digit (6) of the dividend behind the 24 and repeat the process: 246 / 45

Moving on to step 3:
If we divide 246 by 45, we get 5 and a remainder of 21.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 225 from 246 to get 21.
Bring next digit (6) of the dividend behind the 21 and repeat the process: 216 / 45

Going ahead to step 4:
If we divide 216 by 45, we get 4 and a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 54.0
If we subtract 180 from 216, we get 36.
Take the next digit (0) from the dividend and append it to 36, then repeat: 360 / 45

Advancing to step 5:
45 goes into 360 8 times with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 548.0
Subtracting 360 from 360 leaves us with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 45

Moving on to step 6:
45 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 5480.0
Subtract 0 from 1 to get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 45

On to step 7:
If we divide 14 by 45, we get 0 and a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 54800.0
If we subtract 0 from 14, we get 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 45

Advancing to step 8:
45 goes into 145 3 times with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 548003.0
Deduct 135 from 145 and we're left 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.

Let's proceed to step 9:
45 can be fit into 100 2 times, resulting in a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 548003.2
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.

Advancing to step 10:
45 goes into 100 2 times with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 548003.22
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.

The quotient of the division is 548003.22, and the remainder is 0.01.
