395299 divided by 42 
The aim is to understand the frequency of 42 in 395299.

Going ahead to step 1:
When dividing 3 by 42, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 42

Step 2:
When dividing 39 by 42, we get 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Take the next digit (5) from the dividend and append it to 39, then repeat: 395 / 42

Moving on to step 3:
When dividing 395 by 42, we get 9 with a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 378 from 395, we get 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 42

Let's proceed to step 4:
42 goes into 172 4 times with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 94.0
Deduct 168 from 172 and we're left with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 42

On to step 5:
49 divided by 42 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 941.0
Subtracting 42 from 49 leaves us with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 42

Advancing to step 6:
42 can be fit into 79 1 times, resulting in a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 9411.0
If we take 42 away from 79, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 7:
42 can be fit into 370 8 times, resulting in a remainder of 34.
The next digit of our result is 8. 
Result so far: 9411.8
Subtracting 336 from 370 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 8:
340 divided by 42 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 9411.88
Subtract 336 from 340 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 9411.88, with a leftover of 0.004.
