We're dividing 18732427 by 252 
The aim is to understand the frequency of 252 in 18732427.

Let's proceed to step 1:
When dividing 1 by 252, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 252

On to step 2:
18 divided by 252 is 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Take the next digit (7) from the dividend and append it to 18, then repeat: 187 / 252

On to step 3:
252 goes into 187 0 times with a remainder of 187.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 187 to get 187.
Grab the next digit (3) from the dividend, add it to 187, then carry on: 1873 / 252

Step 4:
If we divide 1873 by 252, we get 7 and a remainder of 109.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 109 after subtracting 1764 from 1873.
Grab the next digit (2) from the dividend, add it to 109, then carry on: 1092 / 252

On to step 5:
When dividing 1092 by 252, we get 4 with a remainder of 84.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
If we subtract 1008 from 1092, we get 84.
Bring next digit (4) of the dividend behind the 84 and repeat the process: 844 / 252

On to step 6:
When dividing 844 by 252, we get 3 with a remainder of 88.
Write down 3 as next digit of the result. 
Result so far: 743.0
If we subtract 756 from 844, we get 88.
Fetch the next digit (2) from the dividend, attach it to 88 and continue: 882 / 252

Going ahead to step 7:
252 goes into 882 3 times with a remainder of 126.
The next digit of our result is 3. 
Result so far: 7433.0
If we take 756 away from 882, we end up with 126.
Bring next digit (7) of the dividend behind the 126 and repeat the process: 1267 / 252

Moving on to step 8:
The number 252 fits into 1267 5 times, leaving a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 74335.0
Subtract 1260 from 1267 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 9:
The number 252 fits into 70 0 times, leaving a remainder of 70.
The next digit of our result is 0. 
Result so far: 74335.0
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 10:
252 goes into 700 2 times with a remainder of 196.
Record the quotient 2 as the next digit in the result. 
Result so far: 74335.02
If we subtract 504 from 700, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 11:
1960 divided by 252 is 7 with a remainder of 196.
Put 7 as the next digit of the answer. 
Result so far: 74335.027
If we subtract 1764 from 1960, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 12:
252 can be fit into 1960 7 times, resulting in a remainder of 196.
Record the quotient 7 as the next digit in the result. 
Result so far: 74335.0277
The remainder is 196 after subtracting 1764 from 1960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

The final outcome is 74335.0277, with a leftover of 0.00196.
