We divide 78648145 by 242
The aim is to understand the frequency of 242 in 78648145.

Going ahead to step 1:
The number 242 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 242

Going ahead to step 2:
When dividing 78 by 242, we get 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Include the next digit (6) from the dividend after 78, then repeat: 786 / 242

Going ahead to step 3:
If we divide 786 by 242, we get 3 and a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 726 from 786 to get 60.
Append the next digit (4) from the dividend to 60 and continue with: 604 / 242

Going ahead to step 4:
604 divided by 242 is 2 with a remainder of 120.
Write down 2 as next digit of the result. 
Result so far: 32.0
Subtracting 484 from 604 leaves us with 120.
Include the next digit (8) from the dividend after 120, then repeat: 1208 / 242

Going ahead to step 5:
242 goes into 1208 4 times with a remainder of 240.
The next digit of our result is 4. 
Result so far: 324.0
If we take 968 away from 1208, we end up with 240.
Bring next digit (1) of the dividend behind the 240 and repeat the process: 2401 / 242

Step 6:
The number 242 fits into 2401 9 times, leaving a remainder of 223.
Record the quotient 9 as the next digit in the result. 
Result so far: 3249.0
If we subtract 2178 from 2401, we get 223.
Include the next digit (4) from the dividend after 223, then repeat: 2234 / 242

On to step 7:
The number 242 fits into 2234 9 times, leaving a remainder of 56.
Use 9 as the next digit of our solution. 
Result so far: 32499.0
The remainder is 56 after subtracting 2178 from 2234.
Take the next digit (5) from the dividend and append it to 56, then repeat: 565 / 242

Advancing to step 8:
242 can be fit into 565 2 times, resulting in a remainder of 81.
The number 2 becomes the next digit in our result. 
Result so far: 324992.0
Deduct 484 from 565 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 9:
The number 242 fits into 810 3 times, leaving a remainder of 84.
The number 3 becomes the next digit in our result. 
Result so far: 324992.3
Subtracting 726 from 810 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 10:
242 goes into 840 3 times with a remainder of 114.
Write down 3 as next digit of the result. 
Result so far: 324992.33
Subtract 726 from 840 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

The quotient of the division is 324992.33, and the remainder is 0.114.
