8186019 ÷ 815 
Let's see how many times 815 fits into 8186019.

On to step 1:
The number 815 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 815

On to step 2:
If we divide 81 by 815, we get 0 and a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Include the next digit (8) from the dividend after 81, then repeat: 818 / 815

Moving on to step 3:
The number 815 fits into 818 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 815 from 818, we get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 815

Moving on to step 4:
When dividing 36 by 815, we get 0 with a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 36 after subtracting 0 from 36.
Take the next digit (0) from the dividend and append it to 36, then repeat: 360 / 815

On to step 5:
815 goes into 360 0 times with a remainder of 360.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
If we subtract 0 from 360, we get 360.
Grab the next digit (1) from the dividend, add it to 360, then carry on: 3601 / 815

Moving on to step 6:
If we divide 3601 by 815, we get 4 and a remainder of 341.
Put 4 as the next digit of the answer. 
Result so far: 1004.0
Subtracting 3260 from 3601 leaves us with 341.
Grab the next digit (9) from the dividend, add it to 341, then carry on: 3419 / 815

Advancing to step 7:
815 can be fit into 3419 4 times, resulting in a remainder of 159.
Put 4 as the next digit of the answer. 
Result so far: 10044.0
If we subtract 3260 from 3419, we get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Let's proceed to step 8:
815 goes into 1590 1 times with a remainder of 775.
The next digit of our result is 1. 
Result so far: 10044.1
Subtract 815 from 1590 to get 775.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7750, and continue the process.

Going ahead to step 9:
7750 divided by 815 is 9 with a remainder of 415.
Write down 9 as next digit of the result. 
Result so far: 10044.19
Subtracting 7335 from 7750 leaves us with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Let's proceed to step 10:
When dividing 4150 by 815, we get 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 10044.195
If we take 4075 away from 4150, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 11:
815 goes into 750 0 times with a remainder of 750.
The number 0 becomes the next digit in our result. 
Result so far: 10044.195
Subtracting 0 from 750 leaves us with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Step 12:
815 goes into 7500 9 times with a remainder of 165.
Record the quotient 9 as the next digit in the result. 
Result so far: 10044.19509
If we take 7335 away from 7500, we end up with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

On to step 13:
815 can be fit into 1650 2 times, resulting in a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 10044.195092
If we subtract 1630 from 1650, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
The number 815 fits into 200 0 times, leaving a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 10044.195092
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 15:
The number 815 fits into 2000 2 times, leaving a remainder of 370.
Write down 2 as next digit of the result. 
Result so far: 10044.19509202
The remainder is 370 after subtracting 1630 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

The quotient of the division is 10044.19509202, and the remainder is 3.7e-07.
