489330 divided by 45 
The aim is to understand the frequency of 45 in 489330.

On to step 1:
45 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 45

Moving on to step 2:
If we divide 48 by 45, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 45 from 48 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 45

Step 3:
45 goes into 39 0 times with a remainder of 39.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 39, we end up with 39.
Include the next digit (3) from the dividend after 39, then repeat: 393 / 45

Advancing to step 4:
If we divide 393 by 45, we get 8 and a remainder of 33.
Record the quotient 8 as the next digit in the result. 
Result so far: 108.0
If we take 360 away from 393, we end up with 33.
Include the next digit (3) from the dividend after 33, then repeat: 333 / 45

Let's proceed to step 5:
333 divided by 45 is 7 with a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 1087.0
Deduct 315 from 333 and we're left with 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 45

Let's proceed to step 6:
180 divided by 45 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 10874.0
Subtracting 180 from 180 leaves us 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: 10874.0
Subtract 0 from 0 to 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.

Advancing to step 8:
45 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10874.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 10874.0 with a balance of 0.0.
