We look at the division of 14193201 by 452 
The aim is to understand the frequency of 452 in 14193201.

Step 1:
When dividing 1 by 452, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 452

On to step 2:
If we divide 14 by 452, we get 0 and a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 452

On to step 3:
The number 452 fits into 141 0 times, leaving a remainder of 141.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 141, we end up with 141.
Grab the next digit (9) from the dividend, add it to 141, then carry on: 1419 / 452

Going ahead to step 4:
The number 452 fits into 1419 3 times, leaving a remainder of 63.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 1356 from 1419, we get 63.
Fetch the next digit (3) from the dividend, attach it to 63 and continue: 633 / 452

Advancing to step 5:
If we divide 633 by 452, we get 1 and a remainder of 181.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
The remainder is 181 after subtracting 452 from 633.
Append the next digit (2) from the dividend to 181 and continue with: 1812 / 452

Advancing to step 6:
1812 divided by 452 is 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 314.0
Subtract 1808 from 1812 to get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 452

Let's proceed to step 7:
452 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 3140.0
If we subtract 0 from 40, we get 40.
Take the next digit (1) from the dividend and append it to 40, then repeat: 401 / 452

Let's proceed to step 8:
When dividing 401 by 452, we get 0 with a remainder of 401.
The next digit of our result is 0. 
Result so far: 31400.0
The remainder is 401 after subtracting 0 from 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Let's proceed to step 9:
When dividing 4010 by 452, we get 8 with a remainder of 394.
Record the quotient 8 as the next digit in the result. 
Result so far: 31400.8
Subtracting 3616 from 4010 leaves us with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Going ahead to step 10:
3940 divided by 452 is 8 with a remainder of 324.
Use 8 as the next digit of our solution. 
Result so far: 31400.88
Subtract 3616 from 3940 to get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

After the division, we end up with 31400.88 and a remainder of 0.324.
