199484 ÷ 42 
We want to figure out the number of times 199484 can be divided by 42.

Step 1:
When dividing 1 by 42, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 42

Step 2:
42 can be fit into 19 0 times, resulting in a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 42

On to 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
The remainder is 31 after subtracting 168 from 199.
Grab the next digit (4) from the dividend, add it to 31, then carry on: 314 / 42

On to step 4:
When dividing 314 by 42, we get 7 with a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 47.0
Subtract 294 from 314 to get 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 42

Advancing to step 5:
When dividing 208 by 42, we get 4 with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 474.0
Subtracting 168 from 208 leaves us with 40.
Fetch the next digit (4) from the dividend, attach it to 40 and continue: 404 / 42

Moving on to step 6:
42 goes into 404 9 times with a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 4749.0
Deduct 378 from 404 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 7:
The number 42 fits into 260 6 times, leaving a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 4749.6
If we subtract 252 from 260, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
42 can be fit into 80 1 times, resulting in a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 4749.61
If we subtract 42 from 80, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
42 can be fit into 380 9 times, resulting in a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 4749.619
Subtract 378 from 380 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 10:
The number 42 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 4749.619
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
The number 42 fits into 200 4 times, leaving a remainder of 32.
The next digit of our result is 4. 
Result so far: 4749.61904
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
The number 42 fits into 320 7 times, leaving a remainder of 26.
The next digit of our result is 7. 
Result so far: 4749.619047
The remainder is 26 after subtracting 294 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 13:
260 divided by 42 is 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 4749.6190476
Subtracting 252 from 260 leaves us 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.

Let's proceed to step 14:
When dividing 80 by 42, we get 1 with a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 4749.61904761
Subtract 42 from 80 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Our division results in 4749.61904761 with a remaining 3.8e-08.
