Let's divide 13061515 by 510
We want to figure out the number of times 13061515 can be divided by 510.

Step 1:
1 divided by 510 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 510

Moving on to step 2:
The number 510 fits into 13 0 times, leaving a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 510

Let's proceed to step 3:
510 goes into 130 0 times with a remainder of 130.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 130, we get 130.
Take the next digit (6) from the dividend and append it to 130, then repeat: 1306 / 510

Moving on to step 4:
If we divide 1306 by 510, we get 2 and a remainder of 286.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 1020 from 1306 leaves us with 286.
Include the next digit (1) from the dividend after 286, then repeat: 2861 / 510

Advancing to step 5:
When dividing 2861 by 510, we get 5 with a remainder of 311.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtracting 2550 from 2861 leaves us with 311.
Take the next digit (5) from the dividend and append it to 311, then repeat: 3115 / 510

Step 6:
The number 510 fits into 3115 6 times, leaving a remainder of 55.
Record the quotient 6 as the next digit in the result. 
Result so far: 256.0
Deduct 3060 from 3115 and we're left with 55.
Append the next digit (1) from the dividend to 55 and continue with: 551 / 510

Going ahead to step 7:
510 goes into 551 1 times with a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 2561.0
The remainder is 41 after subtracting 510 from 551.
Include the next digit (5) from the dividend after 41, then repeat: 415 / 510

On to step 8:
If we divide 415 by 510, we get 0 and a remainder of 415.
Write down 0 as next digit of the result. 
Result so far: 25610.0
Subtract 0 from 415 to get 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Step 9:
510 goes into 4150 8 times with a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 25610.8
The remainder is 70 after subtracting 4080 from 4150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 10:
When dividing 700 by 510, we get 1 with a remainder of 190.
Put 1 as the next digit of the answer. 
Result so far: 25610.81
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.

On to step 11:
The number 510 fits into 1900 3 times, leaving a remainder of 370.
Write down 3 as next digit of the result. 
Result so far: 25610.813
If we subtract 1530 from 1900, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 12:
510 can be fit into 3700 7 times, resulting in a remainder of 130.
Use 7 as the next digit of our solution. 
Result so far: 25610.8137
Deduct 3570 from 3700 and we're left with 130.
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 13:
The number 510 fits into 1300 2 times, leaving a remainder of 280.
The number 2 becomes the next digit in our result. 
Result so far: 25610.81372
If we take 1020 away from 1300, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 14:
If we divide 2800 by 510, we get 5 and a remainder of 250.
Record the quotient 5 as the next digit in the result. 
Result so far: 25610.813725
Subtracting 2550 from 2800 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 15:
510 can be fit into 2500 4 times, resulting in a remainder of 460.
Put 4 as the next digit of the answer. 
Result so far: 25610.8137254
Subtracting 2040 from 2500 leaves us with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Going ahead to step 16:
If we divide 4600 by 510, we get 9 and a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 25610.81372549
The remainder is 10 after subtracting 4590 from 4600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 25610.81372549 with a remaining 1e-08.
