We're dividing 450191 by 19 
Let's see how many times 19 fits into 450191.

Let's proceed to step 1:
If we divide 4 by 19, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 19

Moving on to step 2:
If we divide 45 by 19, we get 2 and a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 38 from 45 leaves us with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 19

Advancing to step 3:
19 can be fit into 70 3 times, resulting in a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 23.0
The remainder is 13 after subtracting 57 from 70.
Fetch the next digit (1) from the dividend, attach it to 13 and continue: 131 / 19

Going ahead to step 4:
19 goes into 131 6 times with a remainder of 17.
The number 6 becomes the next digit in our result. 
Result so far: 236.0
If we take 114 away from 131, we end up with 17.
Take the next digit (9) from the dividend and append it to 17, then repeat: 179 / 19

Going ahead to step 5:
If we divide 179 by 19, we get 9 and a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 2369.0
The remainder is 8 after subtracting 171 from 179.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 19

Going ahead to step 6:
19 can be fit into 81 4 times, resulting in a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 23694.0
The remainder is 5 after subtracting 76 from 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
If we divide 50 by 19, we get 2 and a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 23694.2
Subtract 38 from 50 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.

On to step 8:
If we divide 120 by 19, we get 6 and a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 23694.26
Subtract 114 from 120 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
19 goes into 60 3 times with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 23694.263
Deduct 57 from 60 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 10:
19 goes into 30 1 times with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 23694.2631
Deduct 19 from 30 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 11:
If we divide 110 by 19, we get 5 and a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 23694.26315
Subtract 95 from 110 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 12:
When dividing 150 by 19, we get 7 with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 23694.263157
Subtracting 133 from 150 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 13:
When dividing 170 by 19, we get 8 with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 23694.2631578
Subtracting 152 from 170 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 14:
The number 19 fits into 180 9 times, leaving a remainder of 9.
The next digit of our result is 9. 
Result so far: 23694.26315789
Subtract 171 from 180 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

After the division, we end up with 23694.26315789 and a remainder of 9e-09.
