409230 ÷ 45 
The aim is to understand the frequency of 45 in 409230.

Moving on to step 1:
When dividing 4 by 45, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 45

Going ahead to step 2:
45 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Append the next digit (9) from the dividend to 40 and continue with: 409 / 45

On to step 3:
When dividing 409 by 45, we get 9 with a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 405 from 409 leaves us with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 45

Step 4:
45 goes into 42 0 times with a remainder of 42.
The next digit of our result is 0. 
Result so far: 90.0
Deduct 0 from 42 and we're left with 42.
Bring next digit (3) of the dividend behind the 42 and repeat the process: 423 / 45

Step 5:
423 divided by 45 is 9 with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 909.0
If we take 405 away from 423, we end up with 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 45

Going ahead to step 6:
180 divided by 45 is 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 9094.0
If we take 180 away from 180, we end up 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.

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: 9094.0
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.

Step 8:
The number 45 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 9094.0
Subtracting 0 from 0 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.

In conclusion, the division gives 9094.0 with a balance of 0.0.
