We look at the division of 42881775 by 450 
The aim is to understand the frequency of 450 in 42881775.

On to step 1:
450 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 450

Advancing to step 2:
450 can be fit into 42 0 times, resulting in a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Grab the next digit (8) from the dividend, add it to 42, then carry on: 428 / 450

Going ahead to step 3:
If we divide 428 by 450, we get 0 and a remainder of 428.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 428, we end up with 428.
Include the next digit (8) from the dividend after 428, then repeat: 4288 / 450

Advancing to step 4:
If we divide 4288 by 450, we get 9 and a remainder of 238.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 4050 away from 4288, we end up with 238.
Append the next digit (1) from the dividend to 238 and continue with: 2381 / 450

Going ahead to step 5:
The number 450 fits into 2381 5 times, leaving a remainder of 131.
Write down 5 as next digit of the result. 
Result so far: 95.0
Deduct 2250 from 2381 and we're left with 131.
Bring next digit (7) of the dividend behind the 131 and repeat the process: 1317 / 450

Let's proceed to step 6:
1317 divided by 450 is 2 with a remainder of 417.
Use 2 as the next digit of our solution. 
Result so far: 952.0
Subtracting 900 from 1317 leaves us with 417.
Append the next digit (7) from the dividend to 417 and continue with: 4177 / 450

Going ahead to step 7:
450 can be fit into 4177 9 times, resulting in a remainder of 127.
Put 9 as the next digit of the answer. 
Result so far: 9529.0
Subtract 4050 from 4177 to get 127.
Include the next digit (5) from the dividend after 127, then repeat: 1275 / 450

Moving on to step 8:
450 goes into 1275 2 times with a remainder of 375.
The next digit of our result is 2. 
Result so far: 95292.0
Deduct 900 from 1275 and we're left with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Advancing to step 9:
3750 divided by 450 is 8 with a remainder of 150.
Record the quotient 8 as the next digit in the result. 
Result so far: 95292.8
The remainder is 150 after subtracting 3600 from 3750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 10:
1500 divided by 450 is 3 with a remainder of 150.
The number 3 becomes the next digit in our result. 
Result so far: 95292.83
Subtract 1350 from 1500 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 11:
450 can be fit into 1500 3 times, resulting in a remainder of 150.
Put 3 as the next digit of the answer. 
Result so far: 95292.833
Deduct 1350 from 1500 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Our division results in 95292.833 with a remaining 0.015.
