We're dividing 2390747 by 450 
The aim is to understand the frequency of 450 in 2390747.

Step 1:
The number 450 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 450

Moving on to step 2:
450 can be fit into 23 0 times, resulting in a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 450

Going ahead to step 3:
When dividing 239 by 450, we get 0 with a remainder of 239.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 239 to get 239.
Fetch the next digit (0) from the dividend, attach it to 239 and continue: 2390 / 450

Advancing to step 4:
2390 divided by 450 is 5 with a remainder of 140.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 2250 away from 2390, we end up with 140.
Include the next digit (7) from the dividend after 140, then repeat: 1407 / 450

Advancing to step 5:
If we divide 1407 by 450, we get 3 and a remainder of 57.
Use 3 as the next digit of our solution. 
Result so far: 53.0
Deduct 1350 from 1407 and we're left with 57.
Take the next digit (4) from the dividend and append it to 57, then repeat: 574 / 450

On to step 6:
450 can be fit into 574 1 times, resulting in a remainder of 124.
The number 1 becomes the next digit in our result. 
Result so far: 531.0
Subtracting 450 from 574 leaves us with 124.
Fetch the next digit (7) from the dividend, attach it to 124 and continue: 1247 / 450

Going ahead to step 7:
The number 450 fits into 1247 2 times, leaving a remainder of 347.
Record the quotient 2 as the next digit in the result. 
Result so far: 5312.0
Deduct 900 from 1247 and we're left with 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Step 8:
The number 450 fits into 3470 7 times, leaving a remainder of 320.
Write down 7 as next digit of the result. 
Result so far: 5312.7
Subtracting 3150 from 3470 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 9:
450 goes into 3200 7 times with a remainder of 50.
The next digit of our result is 7. 
Result so far: 5312.77
Subtract 3150 from 3200 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 5312.77 with a remaining 0.05.
