806447 ÷ 42 
The aim is to understand the frequency of 42 in 806447.

On to step 1:
42 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 42

Step 2:
The number 42 fits into 80 1 times, leaving a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 42 away from 80, we end up with 38.
Bring next digit (6) of the dividend behind the 38 and repeat the process: 386 / 42

Step 3:
42 goes into 386 9 times with a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we subtract 378 from 386, we get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 42

On to step 4:
84 divided by 42 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 192.0
Subtracting 84 from 84 leaves us with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 42

Let's proceed to step 5:
When dividing 4 by 42, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 1920.0
If we subtract 0 from 4, we get 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 42

Let's proceed to step 6:
47 divided by 42 is 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 19201.0
Subtracting 42 from 47 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
If we divide 50 by 42, we get 1 and a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 19201.1
Deduct 42 from 50 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
80 divided by 42 is 1 with a remainder of 38.
The next digit of our result is 1. 
Result so far: 19201.11
If we take 42 away from 80, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

After the division, we end up with 19201.11 and a remainder of 0.038.
