804972 divided by 42 
The aim is to understand the frequency of 42 in 804972.

Step 1:
42 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 42

Advancing to step 2:
The number 42 fits into 80 1 times, leaving a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 42 from 80 leaves us with 38.
Grab the next digit (4) from the dividend, add it to 38, then carry on: 384 / 42

Going ahead to step 3:
42 can be fit into 384 9 times, resulting in a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 19.0
The remainder is 6 after subtracting 378 from 384.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 42

Advancing to step 4:
If we divide 69 by 42, we get 1 and a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 191.0
Deduct 42 from 69 and we're left with 27.
Take the next digit (7) from the dividend and append it to 27, then repeat: 277 / 42

Let's proceed to step 5:
277 divided by 42 is 6 with a remainder of 25.
Record the quotient 6 as the next digit in the result. 
Result so far: 1916.0
Subtracting 252 from 277 leaves us with 25.
Take the next digit (2) from the dividend and append it to 25, then repeat: 252 / 42

Moving on to step 6:
42 goes into 252 6 times with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 19166.0
The remainder is 0 after subtracting 252 from 252.
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 7:
If we divide 0 by 42, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 19166.0
If we take 0 away from 0, we end up 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.

Going ahead to step 8:
If we divide 0 by 42, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 19166.0
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.

Our division results in 19166.0 with a remaining 0.0.
