609480 divided by 45 
The aim is to understand the frequency of 45 in 609480.

Let's proceed to step 1:
45 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 45

Moving on to step 2:
The number 45 fits into 60 1 times, leaving a remainder of 15.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 15 after subtracting 45 from 60.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 45

Let's proceed to step 3:
159 divided by 45 is 3 with a remainder of 24.
The next digit of our result is 3. 
Result so far: 13.0
If we take 135 away from 159, we end up with 24.
Include the next digit (4) from the dividend after 24, then repeat: 244 / 45

Let's proceed to step 4:
244 divided by 45 is 5 with a remainder of 19.
Write down 5 as next digit of the result. 
Result so far: 135.0
If we subtract 225 from 244, we get 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 45

On to step 5:
45 goes into 198 4 times with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 1354.0
The remainder is 18 after subtracting 180 from 198.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 45

Going ahead to step 6:
The number 45 fits into 180 4 times, leaving a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 13544.0
Deduct 180 from 180 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
The number 45 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 13544.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
45 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 13544.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 13544.0, and the remainder is 0.0.
