We're dividing 191840 by 42 
We want to figure out the number of times 191840 can be divided by 42.

Advancing to step 1:
1 divided by 42 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 42

Advancing to step 2:
42 can be fit into 19 0 times, resulting in a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Grab the next digit (1) from the dividend, add it to 19, then carry on: 191 / 42

Let's proceed to step 3:
If we divide 191 by 42, we get 4 and a remainder of 23.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 168 from 191 leaves us with 23.
Include the next digit (8) from the dividend after 23, then repeat: 238 / 42

Going ahead to step 4:
238 divided by 42 is 5 with a remainder of 28.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Deduct 210 from 238 and we're left with 28.
Fetch the next digit (4) from the dividend, attach it to 28 and continue: 284 / 42

Let's proceed to step 5:
42 can be fit into 284 6 times, resulting in a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 456.0
If we subtract 252 from 284, we get 32.
Grab the next digit (0) from the dividend, add it to 32, then carry on: 320 / 42

Moving on to step 6:
320 divided by 42 is 7 with a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 4567.0
Subtract 294 from 320 to get 26.
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 7:
42 can be fit into 260 6 times, resulting in a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 4567.6
Subtract 252 from 260 to 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.

Moving on to step 8:
42 can be fit into 80 1 times, resulting in a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 4567.61
The remainder is 38 after subtracting 42 from 80.
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 goes into 380 9 times with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 4567.619
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.

On to step 10:
20 divided by 42 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 4567.619
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
42 can be fit into 200 4 times, resulting in a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 4567.61904
Deduct 168 from 200 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 12:
42 goes into 320 7 times with a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 4567.619047
Subtracting 294 from 320 leaves us 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.

On to step 13:
42 can be fit into 260 6 times, resulting in a remainder of 8.
The next digit of our result is 6. 
Result so far: 4567.6190476
Subtract 252 from 260 to 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 14:
42 goes into 80 1 times with a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 4567.61904761
The remainder is 38 after subtracting 42 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final outcome is 4567.61904761, with a leftover of 3.8e-08.
