Let's divide 8015801 by 510
Let's see how many times 510 fits into 8015801.

On to step 1:
The number 510 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 510

Let's proceed to step 2:
When dividing 80 by 510, we get 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Grab the next digit (1) from the dividend, add it to 80, then carry on: 801 / 510

Advancing to step 3:
The number 510 fits into 801 1 times, leaving a remainder of 291.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 510 from 801 to get 291.
Take the next digit (5) from the dividend and append it to 291, then repeat: 2915 / 510

Advancing to step 4:
2915 divided by 510 is 5 with a remainder of 365.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 2550 from 2915 and we're left with 365.
Append the next digit (8) from the dividend to 365 and continue with: 3658 / 510

Moving on to step 5:
3658 divided by 510 is 7 with a remainder of 88.
Use 7 as the next digit of our solution. 
Result so far: 157.0
If we subtract 3570 from 3658, we get 88.
Append the next digit (0) from the dividend to 88 and continue with: 880 / 510

Moving on to step 6:
When dividing 880 by 510, we get 1 with a remainder of 370.
Use 1 as the next digit of our solution. 
Result so far: 1571.0
Deduct 510 from 880 and we're left with 370.
Take the next digit (1) from the dividend and append it to 370, then repeat: 3701 / 510

Moving on to step 7:
The number 510 fits into 3701 7 times, leaving a remainder of 131.
Use 7 as the next digit of our solution. 
Result so far: 15717.0
Subtracting 3570 from 3701 leaves us with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Moving on to step 8:
510 goes into 1310 2 times with a remainder of 290.
Record the quotient 2 as the next digit in the result. 
Result so far: 15717.2
Subtract 1020 from 1310 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 9:
If we divide 2900 by 510, we get 5 and a remainder of 350.
The next digit of our result is 5. 
Result so far: 15717.25
If we take 2550 away from 2900, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 10:
510 can be fit into 3500 6 times, resulting in a remainder of 440.
Use 6 as the next digit of our solution. 
Result so far: 15717.256
Subtract 3060 from 3500 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 11:
When dividing 4400 by 510, we get 8 with a remainder of 320.
Use 8 as the next digit of our solution. 
Result so far: 15717.2568
If we take 4080 away from 4400, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 12:
510 can be fit into 3200 6 times, resulting in a remainder of 140.
Write down 6 as next digit of the result. 
Result so far: 15717.25686
The remainder is 140 after subtracting 3060 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 13:
1400 divided by 510 is 2 with a remainder of 380.
Record the quotient 2 as the next digit in the result. 
Result so far: 15717.256862
If we subtract 1020 from 1400, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 14:
510 can be fit into 3800 7 times, resulting in a remainder of 230.
Put 7 as the next digit of the answer. 
Result so far: 15717.2568627
The remainder is 230 after subtracting 3570 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 15:
If we divide 2300 by 510, we get 4 and a remainder of 260.
The next digit of our result is 4. 
Result so far: 15717.25686274
Subtract 2040 from 2300 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The quotient of the division is 15717.25686274, and the remainder is 2.6e-07.
