We look at the division of 20337240 by 42 
The aim is to understand the frequency of 42 in 20337240.

Step 1:
42 can be fit into 2 0 times, resulting in 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.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 42

On to step 2:
42 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 42

Advancing to step 3:
If we divide 203 by 42, we get 4 and a remainder of 35.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 168 away from 203, we end up with 35.
Bring next digit (3) of the dividend behind the 35 and repeat the process: 353 / 42

Let's proceed to step 4:
42 can be fit into 353 8 times, resulting in a remainder of 17.
Put 8 as the next digit of the answer. 
Result so far: 48.0
Subtracting 336 from 353 leaves us with 17.
Fetch the next digit (7) from the dividend, attach it to 17 and continue: 177 / 42

On to step 5:
42 can be fit into 177 4 times, resulting in a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 484.0
If we take 168 away from 177, we end up with 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 42

Moving on to step 6:
The number 42 fits into 92 2 times, leaving a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 4842.0
Deduct 84 from 92 and we're left with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 42

Step 7:
If we divide 84 by 42, we get 2 and a remainder of 0.
The next digit of our result is 2. 
Result so far: 48422.0
The remainder is 0 after subtracting 84 from 84.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 42

Moving on to step 8:
0 divided by 42 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 484220.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
When dividing 0 by 42, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 484220.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
42 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 484220.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 484220.0, with a leftover of 0.0.
