We're dividing 792099 by 42 
The aim is to understand the frequency of 42 in 792099.

Advancing to step 1:
The number 42 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 42

Going ahead to step 2:
42 can be fit into 79 1 times, resulting in a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 37 after subtracting 42 from 79.
Take the next digit (2) from the dividend and append it to 37, then repeat: 372 / 42

Step 3:
372 divided by 42 is 8 with a remainder of 36.
The next digit of our result is 8. 
Result so far: 18.0
If we take 336 away from 372, we end up with 36.
Bring next digit (0) of the dividend behind the 36 and repeat the process: 360 / 42

Let's proceed to step 4:
42 goes into 360 8 times with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 188.0
Subtract 336 from 360 to get 24.
Take the next digit (9) from the dividend and append it to 24, then repeat: 249 / 42

Moving on to step 5:
The number 42 fits into 249 5 times, leaving a remainder of 39.
Record the quotient 5 as the next digit in the result. 
Result so far: 1885.0
Subtracting 210 from 249 leaves us with 39.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 42

Step 6:
The number 42 fits into 399 9 times, leaving a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 18859.0
The remainder is 21 after subtracting 378 from 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 7:
210 divided by 42 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 18859.5
Subtract 210 from 210 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.

Moving on to step 8:
0 divided by 42 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 18859.5
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.

Going ahead to step 9:
The number 42 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 18859.5
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.

The final outcome is 18859.5, with a leftover of 0.0.
