786744 divided by 42 
The aim is to understand the frequency of 42 in 786744.

Moving on to step 1:
When dividing 7 by 42, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 42

Going ahead to step 2:
If we divide 78 by 42, we get 1 and a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 36 after subtracting 42 from 78.
Grab the next digit (6) from the dividend, add it to 36, then carry on: 366 / 42

Let's proceed to step 3:
366 divided by 42 is 8 with a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtracting 336 from 366 leaves us with 30.
Include the next digit (7) from the dividend after 30, then repeat: 307 / 42

Let's proceed to step 4:
42 can be fit into 307 7 times, resulting in a remainder of 13.
The next digit of our result is 7. 
Result so far: 187.0
The remainder is 13 after subtracting 294 from 307.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 42

Moving on to step 5:
42 can be fit into 134 3 times, resulting in a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 1873.0
Subtracting 126 from 134 leaves us with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 42

Let's proceed to step 6:
The number 42 fits into 84 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 18732.0
If we subtract 84 from 84, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
42 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 18732.0
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.

Let's proceed to step 8:
42 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18732.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 18732.0 with a remainder of 0.0.
