We look at the division of 882686 by 42 
The aim is to understand the frequency of 42 in 882686.

Advancing to step 1:
If we divide 8 by 42, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 42

On to step 2:
42 goes into 88 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 84 from 88, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 42

Moving on to step 3:
If we divide 42 by 42, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 21.0
If we subtract 42 from 42, we get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 42

Going ahead to step 4:
When dividing 6 by 42, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 210.0
If we take 0 away from 6, we end up with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 42

Let's proceed to step 5:
42 goes into 68 1 times with a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 2101.0
The remainder is 26 after subtracting 42 from 68.
Include the next digit (6) from the dividend after 26, then repeat: 266 / 42

Let's proceed to step 6:
42 can be fit into 266 6 times, resulting in a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 21016.0
Subtracting 252 from 266 leaves us 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.

Step 7:
If we divide 140 by 42, we get 3 and a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 21016.3
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.

Step 8:
The number 42 fits into 140 3 times, leaving a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 21016.33
If we take 126 away from 140, 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.

In conclusion, the division gives 21016.33 with a balance of 0.014.
