We look at the division of 15185519 by 784 
Let's see how many times 784 fits into 15185519.

On to step 1:
The number 784 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 784

Let's proceed to step 2:
When dividing 15 by 784, we get 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 784

Let's proceed to step 3:
The number 784 fits into 151 0 times, leaving a remainder of 151.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 151, we get 151.
Take the next digit (8) from the dividend and append it to 151, then repeat: 1518 / 784

Step 4:
784 can be fit into 1518 1 times, resulting in a remainder of 734.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 784 from 1518 and we're left with 734.
Bring next digit (5) of the dividend behind the 734 and repeat the process: 7345 / 784

Going ahead to step 5:
The number 784 fits into 7345 9 times, leaving a remainder of 289.
Write down 9 as next digit of the result. 
Result so far: 19.0
Deduct 7056 from 7345 and we're left with 289.
Bring next digit (5) of the dividend behind the 289 and repeat the process: 2895 / 784

Step 6:
2895 divided by 784 is 3 with a remainder of 543.
Put 3 as the next digit of the answer. 
Result so far: 193.0
If we take 2352 away from 2895, we end up with 543.
Take the next digit (1) from the dividend and append it to 543, then repeat: 5431 / 784

Moving on to step 7:
784 can be fit into 5431 6 times, resulting in a remainder of 727.
Record the quotient 6 as the next digit in the result. 
Result so far: 1936.0
The remainder is 727 after subtracting 4704 from 5431.
Include the next digit (9) from the dividend after 727, then repeat: 7279 / 784

Moving on to step 8:
When dividing 7279 by 784, we get 9 with a remainder of 223.
Write down 9 as next digit of the result. 
Result so far: 19369.0
Subtracting 7056 from 7279 leaves us with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Let's proceed to step 9:
The number 784 fits into 2230 2 times, leaving a remainder of 662.
Write down 2 as next digit of the result. 
Result so far: 19369.2
Deduct 1568 from 2230 and we're left with 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Going ahead to step 10:
The number 784 fits into 6620 8 times, leaving a remainder of 348.
The next digit of our result is 8. 
Result so far: 19369.28
The remainder is 348 after subtracting 6272 from 6620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Let's proceed to step 11:
When dividing 3480 by 784, we get 4 with a remainder of 344.
Record the quotient 4 as the next digit in the result. 
Result so far: 19369.284
If we take 3136 away from 3480, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 12:
3440 divided by 784 is 4 with a remainder of 304.
Record the quotient 4 as the next digit in the result. 
Result so far: 19369.2844
Deduct 3136 from 3440 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

The final result is 19369.2844 with a remainder of 0.00304.
