294499 ÷ 42 
The aim is to understand the frequency of 42 in 294499.

Going ahead to step 1:
When dividing 2 by 42, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 42

Going ahead to step 2:
The number 42 fits into 29 0 times, leaving a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 29 leaves us with 29.
Bring next digit (4) of the dividend behind the 29 and repeat the process: 294 / 42

Let's proceed to step 3:
When dividing 294 by 42, we get 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 0 after subtracting 294 from 294.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 42

Step 4:
42 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 70.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 42

Advancing to step 5:
The number 42 fits into 49 1 times, leaving a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 701.0
Deduct 42 from 49 and we're left with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 42

Moving on to step 6:
When dividing 79 by 42, we get 1 with a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 7011.0
Subtract 42 from 79 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 7:
42 can be fit into 370 8 times, resulting in a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 7011.8
Deduct 336 from 370 and we're left 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.

On to step 8:
If we divide 340 by 42, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 7011.88
If we subtract 336 from 340, we 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.

After the division, we end up with 7011.88 and a remainder of 0.004.
