We look at the division of 99558068 by 452 
The aim is to understand the frequency of 452 in 99558068.

Advancing to step 1:
When dividing 9 by 452, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 452

Going ahead to step 2:
452 can be fit into 99 0 times, resulting in a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Grab the next digit (5) from the dividend, add it to 99, then carry on: 995 / 452

Step 3:
452 goes into 995 2 times with a remainder of 91.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 904 from 995 leaves us with 91.
Grab the next digit (5) from the dividend, add it to 91, then carry on: 915 / 452

Step 4:
The number 452 fits into 915 2 times, leaving a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 22.0
If we take 904 away from 915, we end up with 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 452

Step 5:
When dividing 118 by 452, we get 0 with a remainder of 118.
Use 0 as the next digit of our solution. 
Result so far: 220.0
Subtract 0 from 118 to get 118.
Include the next digit (0) from the dividend after 118, then repeat: 1180 / 452

Advancing to step 6:
When dividing 1180 by 452, we get 2 with a remainder of 276.
Record the quotient 2 as the next digit in the result. 
Result so far: 2202.0
If we subtract 904 from 1180, we get 276.
Include the next digit (6) from the dividend after 276, then repeat: 2766 / 452

Going ahead to step 7:
When dividing 2766 by 452, we get 6 with a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 22026.0
Subtracting 2712 from 2766 leaves us with 54.
Include the next digit (8) from the dividend after 54, then repeat: 548 / 452

Step 8:
The number 452 fits into 548 1 times, leaving a remainder of 96.
Put 1 as the next digit of the answer. 
Result so far: 220261.0
Deduct 452 from 548 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 9:
452 goes into 960 2 times with a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 220261.2
If we subtract 904 from 960, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 10:
452 can be fit into 560 1 times, resulting in a remainder of 108.
The number 1 becomes the next digit in our result. 
Result so far: 220261.21
Deduct 452 from 560 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 11:
1080 divided by 452 is 2 with a remainder of 176.
The next digit of our result is 2. 
Result so far: 220261.212
Subtract 904 from 1080 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 12:
If we divide 1760 by 452, we get 3 and a remainder of 404.
The number 3 becomes the next digit in our result. 
Result so far: 220261.2123
Subtracting 1356 from 1760 leaves us with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Moving on to step 13:
If we divide 4040 by 452, we get 8 and a remainder of 424.
Write down 8 as next digit of the result. 
Result so far: 220261.21238
Subtract 3616 from 4040 to get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Going ahead to step 14:
452 can be fit into 4240 9 times, resulting in a remainder of 172.
Record the quotient 9 as the next digit in the result. 
Result so far: 220261.212389
Subtracting 4068 from 4240 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 15:
When dividing 1720 by 452, we get 3 with a remainder of 364.
The number 3 becomes the next digit in our result. 
Result so far: 220261.2123893
Deduct 1356 from 1720 and we're left with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Going ahead to step 16:
When dividing 3640 by 452, we get 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 220261.21238938
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.

The final outcome is 220261.21238938, with a leftover of 2.4e-08.
