We look at the division of 19135282 by 15 
We want to figure out the number of times 19135282 can be divided by 15.

Advancing to step 1:
The number 15 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 15

Advancing to step 2:
15 goes into 19 1 times with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 15 from 19 to get 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 15

On to step 3:
If we divide 41 by 15, we get 2 and a remainder of 11.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 30 from 41 leaves us with 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 15

Step 4:
If we divide 113 by 15, we get 7 and a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 127.0
If we take 105 away from 113, we end up with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 15

On to step 5:
The number 15 fits into 85 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 1275.0
Subtracting 75 from 85 leaves us with 10.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 15

Let's proceed to step 6:
The number 15 fits into 102 6 times, leaving a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 12756.0
If we take 90 away from 102, we end up with 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 15

Going ahead to step 7:
128 divided by 15 is 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 127568.0
Subtract 120 from 128 to get 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 15

On to step 8:
82 divided by 15 is 5 with a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 1275685.0
Deduct 75 from 82 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 9:
When dividing 70 by 15, we get 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 1275685.4
Subtracting 60 from 70 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
When dividing 100 by 15, we get 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 1275685.46
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
If we divide 100 by 15, we get 6 and a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 1275685.466
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 1275685.466, and the remainder is 0.001.
