We're dividing 199374 by 42 
We're looking to find how many times 42 goes into 199374.

Let's proceed to step 1:
If we divide 1 by 42, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 42

Let's proceed to step 2:
42 goes into 19 0 times with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Include the next digit (9) from the dividend after 19, then repeat: 199 / 42

Step 3:
199 divided by 42 is 4 with a remainder of 31.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 168 from 199 and we're left with 31.
Append the next digit (3) from the dividend to 31 and continue with: 313 / 42

Let's proceed to step 4:
42 can be fit into 313 7 times, resulting in a remainder of 19.
The next digit of our result is 7. 
Result so far: 47.0
Subtract 294 from 313 to get 19.
Take the next digit (7) from the dividend and append it to 19, then repeat: 197 / 42

On to step 5:
If we divide 197 by 42, we get 4 and a remainder of 29.
The number 4 becomes the next digit in our result. 
Result so far: 474.0
If we subtract 168 from 197, we get 29.
Bring next digit (4) of the dividend behind the 29 and repeat the process: 294 / 42

Step 6:
The number 42 fits into 294 7 times, leaving a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 4747.0
If we subtract 294 from 294, 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.

Going ahead to step 7:
0 divided by 42 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 4747.0
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.

On to step 8:
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: 4747.0
If we subtract 0 from 0, 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.

The final result is 4747.0 with a remainder of 0.0.
