We're dividing 1248084 by 450 
The aim is to understand the frequency of 450 in 1248084.

On to step 1:
450 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 450

Going ahead to step 2:
450 can be fit into 12 0 times, resulting in a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 450

Advancing to step 3:
124 divided by 450 is 0 with a remainder of 124.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 124, we end up with 124.
Fetch the next digit (8) from the dividend, attach it to 124 and continue: 1248 / 450

On to step 4:
450 can be fit into 1248 2 times, resulting in a remainder of 348.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 900 from 1248 leaves us with 348.
Bring next digit (0) of the dividend behind the 348 and repeat the process: 3480 / 450

Going ahead to step 5:
If we divide 3480 by 450, we get 7 and a remainder of 330.
Put 7 as the next digit of the answer. 
Result so far: 27.0
If we subtract 3150 from 3480, we get 330.
Append the next digit (8) from the dividend to 330 and continue with: 3308 / 450

Going ahead to step 6:
When dividing 3308 by 450, we get 7 with a remainder of 158.
Record the quotient 7 as the next digit in the result. 
Result so far: 277.0
Subtract 3150 from 3308 to get 158.
Append the next digit (4) from the dividend to 158 and continue with: 1584 / 450

Going ahead to step 7:
450 can be fit into 1584 3 times, resulting in a remainder of 234.
The number 3 becomes the next digit in our result. 
Result so far: 2773.0
The remainder is 234 after subtracting 1350 from 1584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Going ahead to step 8:
When dividing 2340 by 450, we get 5 with a remainder of 90.
Write down 5 as next digit of the result. 
Result so far: 2773.5
The remainder is 90 after subtracting 2250 from 2340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 9:
450 goes into 900 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 2773.52
If we subtract 900 from 900, 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.

Going ahead to step 10:
450 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2773.52
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.

Moving on to step 11:
The number 450 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2773.52
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.

In conclusion, the division gives 2773.52 with a balance of 0.0.
