794003 ÷ 42 
We're looking to find how many times 42 goes into 794003.

Step 1:
42 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 42

Let's proceed to step 2:
When dividing 79 by 42, we get 1 with a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 37 after subtracting 42 from 79.
Grab the next digit (4) from the dividend, add it to 37, then carry on: 374 / 42

Step 3:
42 can be fit into 374 8 times, resulting in a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 336 from 374 to get 38.
Bring next digit (0) of the dividend behind the 38 and repeat the process: 380 / 42

Advancing to step 4:
380 divided by 42 is 9 with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 189.0
Deduct 378 from 380 and we're left with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 42

Advancing to step 5:
42 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1890.0
Deduct 0 from 20 and we're left with 20.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 42

On to step 6:
203 divided by 42 is 4 with a remainder of 35.
The next digit of our result is 4. 
Result so far: 18904.0
Subtract 168 from 203 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 7:
350 divided by 42 is 8 with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 18904.8
If we take 336 away from 350, 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.

Let's proceed to step 8:
42 can be fit into 140 3 times, resulting in a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 18904.83
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.

Moving on to step 9:
42 can be fit into 140 3 times, resulting in a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 18904.833
Subtracting 126 from 140 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.

Our division results in 18904.833 with a remaining 0.0014.
