We look at the division of 2371820 by 242 
The aim is to understand the frequency of 242 in 2371820.

Let's proceed to step 1:
The number 242 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 242

Advancing to step 2:
When dividing 23 by 242, we get 0 with a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Append the next digit (7) from the dividend to 23 and continue with: 237 / 242

Step 3:
237 divided by 242 is 0 with a remainder of 237.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 237 leaves us with 237.
Take the next digit (1) from the dividend and append it to 237, then repeat: 2371 / 242

On to step 4:
242 goes into 2371 9 times with a remainder of 193.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 2178 from 2371 leaves us with 193.
Take the next digit (8) from the dividend and append it to 193, then repeat: 1938 / 242

Let's proceed to step 5:
When dividing 1938 by 242, we get 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 98.0
If we take 1936 away from 1938, we end up with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 242

Step 6:
The number 242 fits into 22 0 times, leaving a remainder of 22.
The number 0 becomes the next digit in our result. 
Result so far: 980.0
Subtract 0 from 22 to get 22.
Append the next digit (0) from the dividend to 22 and continue with: 220 / 242

Advancing to step 7:
220 divided by 242 is 0 with a remainder of 220.
Write down 0 as next digit of the result. 
Result so far: 9800.0
The remainder is 220 after subtracting 0 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 8:
242 goes into 2200 9 times with a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 9800.9
If we take 2178 away from 2200, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
If we divide 220 by 242, we get 0 and a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 9800.9
Subtract 0 from 220 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 10:
If we divide 2200 by 242, we get 9 and a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 9800.909
Deduct 2178 from 2200 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
220 divided by 242 is 0 with a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 9800.909
Subtract 0 from 220 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 12:
If we divide 2200 by 242, we get 9 and a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 9800.90909
Deduct 2178 from 2200 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 13:
The number 242 fits into 220 0 times, leaving a remainder of 220.
Write down 0 as next digit of the result. 
Result so far: 9800.90909
If we take 0 away from 220, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 14:
242 can be fit into 2200 9 times, resulting in a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 9800.9090909
Deduct 2178 from 2200 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 15:
The number 242 fits into 220 0 times, leaving a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 9800.9090909
If we take 0 away from 220, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

The quotient of the division is 9800.9090909, and the remainder is 2.2e-07.
