18590393 ÷ 452 
The aim is to understand the frequency of 452 in 18590393.

On to step 1:
The number 452 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 452

Step 2:
452 goes into 18 0 times with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Include the next digit (5) from the dividend after 18, then repeat: 185 / 452

On to step 3:
185 divided by 452 is 0 with a remainder of 185.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 185 leaves us with 185.
Take the next digit (9) from the dividend and append it to 185, then repeat: 1859 / 452

Going ahead to step 4:
452 goes into 1859 4 times with a remainder of 51.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 1808 from 1859, we get 51.
Include the next digit (0) from the dividend after 51, then repeat: 510 / 452

Moving on to step 5:
452 can be fit into 510 1 times, resulting in a remainder of 58.
Use 1 as the next digit of our solution. 
Result so far: 41.0
Deduct 452 from 510 and we're left with 58.
Take the next digit (3) from the dividend and append it to 58, then repeat: 583 / 452

Step 6:
If we divide 583 by 452, we get 1 and a remainder of 131.
Use 1 as the next digit of our solution. 
Result so far: 411.0
If we subtract 452 from 583, we get 131.
Take the next digit (9) from the dividend and append it to 131, then repeat: 1319 / 452

Let's proceed to step 7:
1319 divided by 452 is 2 with a remainder of 415.
Record the quotient 2 as the next digit in the result. 
Result so far: 4112.0
Subtracting 904 from 1319 leaves us with 415.
Bring next digit (3) of the dividend behind the 415 and repeat the process: 4153 / 452

Advancing to step 8:
When dividing 4153 by 452, we get 9 with a remainder of 85.
Use 9 as the next digit of our solution. 
Result so far: 41129.0
If we take 4068 away from 4153, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 9:
850 divided by 452 is 1 with a remainder of 398.
The number 1 becomes the next digit in our result. 
Result so far: 41129.1
Subtracting 452 from 850 leaves us with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Advancing to step 10:
When dividing 3980 by 452, we get 8 with a remainder of 364.
The next digit of our result is 8. 
Result so far: 41129.18
The remainder is 364 after subtracting 3616 from 3980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

On to step 11:
452 can be fit into 3640 8 times, resulting in a remainder of 24.
The next digit of our result is 8. 
Result so far: 41129.188
If we take 3616 away from 3640, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 41129.188 with a balance of 0.0024.
