We're dividing 99896458 by 450 
The aim is to understand the frequency of 450 in 99896458.

Step 1:
9 divided by 450 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 450

Let's proceed to step 2:
When dividing 99 by 450, we get 0 with a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Append the next digit (8) from the dividend to 99 and continue with: 998 / 450

On to step 3:
The number 450 fits into 998 2 times, leaving a remainder of 98.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 900 from 998 leaves us with 98.
Bring next digit (9) of the dividend behind the 98 and repeat the process: 989 / 450

Advancing to step 4:
450 can be fit into 989 2 times, resulting in a remainder of 89.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we subtract 900 from 989, we get 89.
Take the next digit (6) from the dividend and append it to 89, then repeat: 896 / 450

Step 5:
The number 450 fits into 896 1 times, leaving a remainder of 446.
Use 1 as the next digit of our solution. 
Result so far: 221.0
Subtracting 450 from 896 leaves us with 446.
Grab the next digit (4) from the dividend, add it to 446, then carry on: 4464 / 450

Moving on to step 6:
The number 450 fits into 4464 9 times, leaving a remainder of 414.
Put 9 as the next digit of the answer. 
Result so far: 2219.0
Deduct 4050 from 4464 and we're left with 414.
Bring next digit (5) of the dividend behind the 414 and repeat the process: 4145 / 450

Going ahead to step 7:
450 can be fit into 4145 9 times, resulting in a remainder of 95.
Record the quotient 9 as the next digit in the result. 
Result so far: 22199.0
Subtract 4050 from 4145 to get 95.
Include the next digit (8) from the dividend after 95, then repeat: 958 / 450

Step 8:
The number 450 fits into 958 2 times, leaving a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 221992.0
The remainder is 58 after subtracting 900 from 958.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 9:
The number 450 fits into 580 1 times, leaving a remainder of 130.
The number 1 becomes the next digit in our result. 
Result so far: 221992.1
Subtracting 450 from 580 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 10:
450 can be fit into 1300 2 times, resulting in a remainder of 400.
Put 2 as the next digit of the answer. 
Result so far: 221992.12
Subtract 900 from 1300 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 11:
450 goes into 4000 8 times with a remainder of 400.
Use 8 as the next digit of our solution. 
Result so far: 221992.128
Subtract 3600 from 4000 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 12:
450 can be fit into 4000 8 times, resulting in a remainder of 400.
Put 8 as the next digit of the answer. 
Result so far: 221992.1288
The remainder is 400 after subtracting 3600 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Our division results in 221992.1288 with a remaining 0.004.
