We're dividing 18915145 by 519 
Let's see how many times 519 fits into 18915145.

Going ahead to step 1:
The number 519 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 519

Step 2:
18 divided by 519 is 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Append the next digit (9) from the dividend to 18 and continue with: 189 / 519

Moving on to step 3:
189 divided by 519 is 0 with a remainder of 189.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 189 leaves us with 189.
Bring next digit (1) of the dividend behind the 189 and repeat the process: 1891 / 519

On to step 4:
When dividing 1891 by 519, we get 3 with a remainder of 334.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 1557 from 1891 leaves us with 334.
Bring next digit (5) of the dividend behind the 334 and repeat the process: 3345 / 519

Moving on to step 5:
The number 519 fits into 3345 6 times, leaving a remainder of 231.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
If we subtract 3114 from 3345, we get 231.
Take the next digit (1) from the dividend and append it to 231, then repeat: 2311 / 519

Step 6:
When dividing 2311 by 519, we get 4 with a remainder of 235.
The next digit of our result is 4. 
Result so far: 364.0
If we take 2076 away from 2311, we end up with 235.
Fetch the next digit (4) from the dividend, attach it to 235 and continue: 2354 / 519

Moving on to step 7:
If we divide 2354 by 519, we get 4 and a remainder of 278.
The next digit of our result is 4. 
Result so far: 3644.0
If we subtract 2076 from 2354, we get 278.
Take the next digit (5) from the dividend and append it to 278, then repeat: 2785 / 519

Advancing to step 8:
519 can be fit into 2785 5 times, resulting in a remainder of 190.
Put 5 as the next digit of the answer. 
Result so far: 36445.0
Deduct 2595 from 2785 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 9:
519 can be fit into 1900 3 times, resulting in a remainder of 343.
The number 3 becomes the next digit in our result. 
Result so far: 36445.3
If we subtract 1557 from 1900, we get 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Moving on to step 10:
When dividing 3430 by 519, we get 6 with a remainder of 316.
Record the quotient 6 as the next digit in the result. 
Result so far: 36445.36
If we subtract 3114 from 3430, we get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Advancing to step 11:
When dividing 3160 by 519, we get 6 with a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 36445.366
The remainder is 46 after subtracting 3114 from 3160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final result is 36445.366 with a remainder of 0.0046.
