20775664 ÷ 513 
Let's see how many times 513 fits into 20775664.

On to step 1:
When dividing 2 by 513, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 513

Going ahead to step 2:
The number 513 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Append the next digit (7) from the dividend to 20 and continue with: 207 / 513

Let's proceed to step 3:
207 divided by 513 is 0 with a remainder of 207.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 207, we end up with 207.
Append the next digit (7) from the dividend to 207 and continue with: 2077 / 513

Let's proceed to step 4:
If we divide 2077 by 513, we get 4 and a remainder of 25.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 2052 away from 2077, we end up with 25.
Append the next digit (5) from the dividend to 25 and continue with: 255 / 513

Advancing to step 5:
513 can be fit into 255 0 times, resulting in a remainder of 255.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
If we subtract 0 from 255, we get 255.
Take the next digit (6) from the dividend and append it to 255, then repeat: 2556 / 513

Going ahead to step 6:
When dividing 2556 by 513, we get 4 with a remainder of 504.
Put 4 as the next digit of the answer. 
Result so far: 404.0
If we subtract 2052 from 2556, we get 504.
Fetch the next digit (6) from the dividend, attach it to 504 and continue: 5046 / 513

Let's proceed to step 7:
513 goes into 5046 9 times with a remainder of 429.
Write down 9 as next digit of the result. 
Result so far: 4049.0
If we subtract 4617 from 5046, we get 429.
Grab the next digit (4) from the dividend, add it to 429, then carry on: 4294 / 513

Step 8:
513 can be fit into 4294 8 times, resulting in a remainder of 190.
Use 8 as the next digit of our solution. 
Result so far: 40498.0
Subtracting 4104 from 4294 leaves us 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.

Let's proceed to step 9:
If we divide 1900 by 513, we get 3 and a remainder of 361.
The number 3 becomes the next digit in our result. 
Result so far: 40498.3
The remainder is 361 after subtracting 1539 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Going ahead to step 10:
If we divide 3610 by 513, we get 7 and a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 40498.37
Subtracting 3591 from 3610 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 11:
When dividing 190 by 513, we get 0 with a remainder of 190.
Use 0 as the next digit of our solution. 
Result so far: 40498.37
Subtracting 0 from 190 leaves us 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.

Going ahead to step 12:
When dividing 1900 by 513, we get 3 with a remainder of 361.
Write down 3 as next digit of the result. 
Result so far: 40498.3703
Deduct 1539 from 1900 and we're left with 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Moving on to step 13:
513 goes into 3610 7 times with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 40498.37037
The remainder is 19 after subtracting 3591 from 3610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 14:
190 divided by 513 is 0 with a remainder of 190.
Record the quotient 0 as the next digit in the result. 
Result so far: 40498.37037
If we take 0 away from 190, we end up 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.

Going ahead to step 15:
If we divide 1900 by 513, we get 3 and a remainder of 361.
Record the quotient 3 as the next digit in the result. 
Result so far: 40498.3703703
Subtracting 1539 from 1900 leaves us with 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Going ahead to step 16:
513 can be fit into 3610 7 times, resulting in a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 40498.37037037
Subtract 3591 from 3610 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 40498.37037037, with a leftover of 1.9e-08.
