We're dividing 15482980 by 510 
Let's see how many times 510 fits into 15482980.

Step 1:
510 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 510

Moving on to step 2:
510 goes into 15 0 times with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 510

Going ahead to step 3:
If we divide 154 by 510, we get 0 and a remainder of 154.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 154 after subtracting 0 from 154.
Take the next digit (8) from the dividend and append it to 154, then repeat: 1548 / 510

Going ahead to step 4:
When dividing 1548 by 510, we get 3 with a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 1530 from 1548 leaves us with 18.
Grab the next digit (2) from the dividend, add it to 18, then carry on: 182 / 510

Let's proceed to step 5:
510 can be fit into 182 0 times, resulting in a remainder of 182.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Subtract 0 from 182 to get 182.
Append the next digit (9) from the dividend to 182 and continue with: 1829 / 510

Advancing to step 6:
If we divide 1829 by 510, we get 3 and a remainder of 299.
Use 3 as the next digit of our solution. 
Result so far: 303.0
If we take 1530 away from 1829, we end up with 299.
Grab the next digit (8) from the dividend, add it to 299, then carry on: 2998 / 510

On to step 7:
When dividing 2998 by 510, we get 5 with a remainder of 448.
Write down 5 as next digit of the result. 
Result so far: 3035.0
If we take 2550 away from 2998, we end up with 448.
Take the next digit (0) from the dividend and append it to 448, then repeat: 4480 / 510

Going ahead to step 8:
510 can be fit into 4480 8 times, resulting in a remainder of 400.
Record the quotient 8 as the next digit in the result. 
Result so far: 30358.0
If we subtract 4080 from 4480, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 9:
510 can be fit into 4000 7 times, resulting in a remainder of 430.
Use 7 as the next digit of our solution. 
Result so far: 30358.7
If we subtract 3570 from 4000, we get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Advancing to step 10:
The number 510 fits into 4300 8 times, leaving a remainder of 220.
The next digit of our result is 8. 
Result so far: 30358.78
If we take 4080 away from 4300, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 11:
510 can be fit into 2200 4 times, resulting in a remainder of 160.
The number 4 becomes the next digit in our result. 
Result so far: 30358.784
If we subtract 2040 from 2200, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 12:
The number 510 fits into 1600 3 times, leaving a remainder of 70.
Put 3 as the next digit of the answer. 
Result so far: 30358.7843
If we subtract 1530 from 1600, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 13:
510 goes into 700 1 times with a remainder of 190.
The number 1 becomes the next digit in our result. 
Result so far: 30358.78431
The remainder is 190 after subtracting 510 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 14:
If we divide 1900 by 510, we get 3 and a remainder of 370.
The next digit of our result is 3. 
Result so far: 30358.784313
Deduct 1530 from 1900 and we're left with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

On to step 15:
When dividing 3700 by 510, we get 7 with a remainder of 130.
Put 7 as the next digit of the answer. 
Result so far: 30358.7843137
The remainder is 130 after subtracting 3570 from 3700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 16:
510 goes into 1300 2 times with a remainder of 280.
Record the quotient 2 as the next digit in the result. 
Result so far: 30358.78431372
If we subtract 1020 from 1300, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

After the division, we end up with 30358.78431372 and a remainder of 2.8e-07.
