We look at the division of 75921750 by 242 
The aim is to understand the frequency of 242 in 75921750.

Let's proceed to step 1:
242 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 242

On to step 2:
If we divide 75 by 242, we get 0 and a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Take the next digit (9) from the dividend and append it to 75, then repeat: 759 / 242

Going ahead to step 3:
When dividing 759 by 242, we get 3 with a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 33 after subtracting 726 from 759.
Fetch the next digit (2) from the dividend, attach it to 33 and continue: 332 / 242

Going ahead to step 4:
If we divide 332 by 242, we get 1 and a remainder of 90.
Write down 1 as next digit of the result. 
Result so far: 31.0
Deduct 242 from 332 and we're left with 90.
Fetch the next digit (1) from the dividend, attach it to 90 and continue: 901 / 242

Step 5:
The number 242 fits into 901 3 times, leaving a remainder of 175.
The next digit of our result is 3. 
Result so far: 313.0
The remainder is 175 after subtracting 726 from 901.
Include the next digit (7) from the dividend after 175, then repeat: 1757 / 242

On to step 6:
242 goes into 1757 7 times with a remainder of 63.
Write down 7 as next digit of the result. 
Result so far: 3137.0
The remainder is 63 after subtracting 1694 from 1757.
Bring next digit (5) of the dividend behind the 63 and repeat the process: 635 / 242

Let's proceed to step 7:
If we divide 635 by 242, we get 2 and a remainder of 151.
Use 2 as the next digit of our solution. 
Result so far: 31372.0
If we take 484 away from 635, we end up with 151.
Take the next digit (0) from the dividend and append it to 151, then repeat: 1510 / 242

On to step 8:
When dividing 1510 by 242, we get 6 with a remainder of 58.
The next digit of our result is 6. 
Result so far: 313726.0
If we subtract 1452 from 1510, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 9:
If we divide 580 by 242, we get 2 and a remainder of 96.
The next digit of our result is 2. 
Result so far: 313726.2
Subtracting 484 from 580 leaves us 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.

Going ahead to step 10:
960 divided by 242 is 3 with a remainder of 234.
The number 3 becomes the next digit in our result. 
Result so far: 313726.23
If we take 726 away from 960, we end up with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Advancing to step 11:
When dividing 2340 by 242, we get 9 with a remainder of 162.
Use 9 as the next digit of our solution. 
Result so far: 313726.239
Subtract 2178 from 2340 to get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Moving on to step 12:
If we divide 1620 by 242, we get 6 and a remainder of 168.
The number 6 becomes the next digit in our result. 
Result so far: 313726.2396
Subtracting 1452 from 1620 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Advancing to step 13:
When dividing 1680 by 242, we get 6 with a remainder of 228.
Write down 6 as next digit of the result. 
Result so far: 313726.23966
If we take 1452 away from 1680, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

After the division, we end up with 313726.23966 and a remainder of 0.000228.
