We look at the division of 12174025 by 450 
The aim is to understand the frequency of 450 in 12174025.

Going ahead to step 1:
When dividing 1 by 450, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 450

Advancing to step 2:
12 divided by 450 is 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 450

Going ahead to step 3:
121 divided by 450 is 0 with a remainder of 121.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 121 after subtracting 0 from 121.
Include the next digit (7) from the dividend after 121, then repeat: 1217 / 450

Step 4:
If we divide 1217 by 450, we get 2 and a remainder of 317.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 900 from 1217, we get 317.
Take the next digit (4) from the dividend and append it to 317, then repeat: 3174 / 450

Advancing to step 5:
450 goes into 3174 7 times with a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 27.0
The remainder is 24 after subtracting 3150 from 3174.
Grab the next digit (0) from the dividend, add it to 24, then carry on: 240 / 450

Advancing to step 6:
When dividing 240 by 450, we get 0 with a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 270.0
If we take 0 away from 240, we end up with 240.
Fetch the next digit (2) from the dividend, attach it to 240 and continue: 2402 / 450

Going ahead to step 7:
450 goes into 2402 5 times with a remainder of 152.
Put 5 as the next digit of the answer. 
Result so far: 2705.0
If we take 2250 away from 2402, we end up with 152.
Include the next digit (5) from the dividend after 152, then repeat: 1525 / 450

On to step 8:
450 goes into 1525 3 times with a remainder of 175.
The next digit of our result is 3. 
Result so far: 27053.0
Subtracting 1350 from 1525 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 9:
450 goes into 1750 3 times with a remainder of 400.
Put 3 as the next digit of the answer. 
Result so far: 27053.3
Subtract 1350 from 1750 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.

Let's proceed to step 10:
450 goes into 4000 8 times with a remainder of 400.
Use 8 as the next digit of our solution. 
Result so far: 27053.38
Deduct 3600 from 4000 and we're left with 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 can be fit into 4000 8 times, resulting in a remainder of 400.
Use 8 as the next digit of our solution. 
Result so far: 27053.388
If we take 3600 away from 4000, we end up with 400.
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 27053.388 with a remaining 0.04.
