We look at the division of 107702 by 42 
The aim is to understand the frequency of 42 in 107702.

Let's proceed to step 1:
When dividing 1 by 42, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 42

Let's proceed to step 2:
42 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 42

Step 3:
If we divide 107 by 42, we get 2 and a remainder of 23.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 84 from 107 to get 23.
Include the next digit (7) from the dividend after 23, then repeat: 237 / 42

Going ahead to step 4:
If we divide 237 by 42, we get 5 and a remainder of 27.
The next digit of our result is 5. 
Result so far: 25.0
Deduct 210 from 237 and we're left with 27.
Append the next digit (0) from the dividend to 27 and continue with: 270 / 42

On to step 5:
When dividing 270 by 42, we get 6 with a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 256.0
Subtract 252 from 270 to get 18.
Append the next digit (2) from the dividend to 18 and continue with: 182 / 42

Let's proceed to step 6:
182 divided by 42 is 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 2564.0
If we take 168 away from 182, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
42 goes into 140 3 times with a remainder of 14.
The next digit of our result is 3. 
Result so far: 2564.3
If we subtract 126 from 140, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
The number 42 fits into 140 3 times, leaving a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 2564.33
Subtract 126 from 140 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 2564.33 with a remaining 0.014.
