496818 ÷ 42 
The aim is to understand the frequency of 42 in 496818.

Going ahead to step 1:
When dividing 4 by 42, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 42

Moving on to step 2:
49 divided by 42 is 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 42 from 49 leaves us with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 42

On to step 3:
42 goes into 76 1 times with a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 34 after subtracting 42 from 76.
Include the next digit (8) from the dividend after 34, then repeat: 348 / 42

Going ahead to step 4:
If we divide 348 by 42, we get 8 and a remainder of 12.
The next digit of our result is 8. 
Result so far: 118.0
If we subtract 336 from 348, we get 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 42

Step 5:
The number 42 fits into 121 2 times, leaving a remainder of 37.
Put 2 as the next digit of the answer. 
Result so far: 1182.0
If we subtract 84 from 121, we get 37.
Take the next digit (8) from the dividend and append it to 37, then repeat: 378 / 42

Step 6:
If we divide 378 by 42, we get 9 and a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 11829.0
Subtracting 378 from 378 leaves us 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.

Advancing to step 7:
42 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 11829.0
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.

Going ahead to step 8:
The number 42 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 11829.0
Subtracting 0 from 0 leaves us 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.

After the division, we end up with 11829.0 and a remainder of 0.0.
