20968666 divided by 513 
We want to divide 20968666 by 513.

Step 1:
When dividing 2 by 513, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 513

Moving on to step 2:
When dividing 20 by 513, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.

Advancing to step 4:
513 goes into 2096 4 times with a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 2052 from 2096 and we're left with 44.
Include the next digit (8) from the dividend after 44, then repeat: 448 / 513

Let's proceed to step 5:
513 goes into 448 0 times with a remainder of 448.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Subtracting 0 from 448 leaves us with 448.
Append the next digit (6) from the dividend to 448 and continue with: 4486 / 513

On to step 6:
513 can be fit into 4486 8 times, resulting in a remainder of 382.
Record the quotient 8 as the next digit in the result. 
Result so far: 408.0
The remainder is 382 after subtracting 4104 from 4486.
Include the next digit (6) from the dividend after 382, then repeat: 3826 / 513

Step 7:
513 goes into 3826 7 times with a remainder of 235.
Record the quotient 7 as the next digit in the result. 
Result so far: 4087.0
Subtracting 3591 from 3826 leaves us with 235.
Grab the next digit (6) from the dividend, add it to 235, then carry on: 2356 / 513

On to step 8:
The number 513 fits into 2356 4 times, leaving a remainder of 304.
The number 4 becomes the next digit in our result. 
Result so far: 40874.0
Subtract 2052 from 2356 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Moving on to step 9:
513 can be fit into 3040 5 times, resulting in a remainder of 475.
Use 5 as the next digit of our solution. 
Result so far: 40874.5
If we take 2565 away from 3040, we end up with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Going ahead to step 10:
4750 divided by 513 is 9 with a remainder of 133.
Write down 9 as next digit of the result. 
Result so far: 40874.59
Subtracting 4617 from 4750 leaves us with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

On to step 11:
513 can be fit into 1330 2 times, resulting in a remainder of 304.
Record the quotient 2 as the next digit in the result. 
Result so far: 40874.592
If we subtract 1026 from 1330, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Let's proceed to step 12:
The number 513 fits into 3040 5 times, leaving a remainder of 475.
Put 5 as the next digit of the answer. 
Result so far: 40874.5925
If we take 2565 away from 3040, we end up with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Step 13:
4750 divided by 513 is 9 with a remainder of 133.
Use 9 as the next digit of our solution. 
Result so far: 40874.59259
Subtracting 4617 from 4750 leaves us with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Moving on to step 14:
1330 divided by 513 is 2 with a remainder of 304.
Put 2 as the next digit of the answer. 
Result so far: 40874.592592
Deduct 1026 from 1330 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Going ahead to step 15:
513 can be fit into 3040 5 times, resulting in a remainder of 475.
Put 5 as the next digit of the answer. 
Result so far: 40874.5925925
Subtracting 2565 from 3040 leaves us with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

On to step 16:
The number 513 fits into 4750 9 times, leaving a remainder of 133.
Record the quotient 9 as the next digit in the result. 
Result so far: 40874.59259259
The remainder is 133 after subtracting 4617 from 4750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.
