We divide 191517 by 42
We want to figure out the number of times 191517 can be divided by 42.

Let's proceed to step 1:
42 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 42

Step 2:
19 divided by 42 is 0 with 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.
Fetch the next digit (1) from the dividend, attach it to 19 and continue: 191 / 42

Going ahead to step 3:
If we divide 191 by 42, we get 4 and a remainder of 23.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 168 from 191, we get 23.
Append the next digit (5) from the dividend to 23 and continue with: 235 / 42

Advancing to step 4:
235 divided by 42 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 45.0
The remainder is 25 after subtracting 210 from 235.
Append the next digit (1) from the dividend to 25 and continue with: 251 / 42

Going ahead to step 5:
When dividing 251 by 42, we get 5 with a remainder of 41.
Put 5 as the next digit of the answer. 
Result so far: 455.0
Deduct 210 from 251 and we're left with 41.
Bring next digit (7) of the dividend behind the 41 and repeat the process: 417 / 42

Moving on to step 6:
When dividing 417 by 42, we get 9 with a remainder of 39.
The next digit of our result is 9. 
Result so far: 4559.0
If we take 378 away from 417, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
42 goes into 390 9 times with a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 4559.9
Deduct 378 from 390 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
120 divided by 42 is 2 with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 4559.92
Deduct 84 from 120 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
360 divided by 42 is 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 4559.928
If we take 336 away from 360, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
42 can be fit into 240 5 times, resulting in a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 4559.9285
The remainder is 30 after subtracting 210 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
The number 42 fits into 300 7 times, leaving a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 4559.92857
If we take 294 away from 300, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 12:
If we divide 60 by 42, we get 1 and a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 4559.928571
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 13:
When dividing 180 by 42, we get 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 4559.9285714
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 14:
The number 42 fits into 120 2 times, leaving a remainder of 36.
The next digit of our result is 2. 
Result so far: 4559.92857142
If we subtract 84 from 120, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final result is 4559.92857142 with a remainder of 3.6e-08.
