Let's divide 20639349 by 517
Let's see how many times 517 fits into 20639349.

On to step 1:
517 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 517

On to step 2:
When dividing 20 by 517, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Take the next digit (6) from the dividend and append it to 20, then repeat: 206 / 517

Advancing to step 3:
The number 517 fits into 206 0 times, leaving a remainder of 206.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 206 to get 206.
Fetch the next digit (3) from the dividend, attach it to 206 and continue: 2063 / 517

Advancing to step 4:
517 can be fit into 2063 3 times, resulting in a remainder of 512.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 1551 from 2063 leaves us with 512.
Append the next digit (9) from the dividend to 512 and continue with: 5129 / 517

Advancing to step 5:
If we divide 5129 by 517, we get 9 and a remainder of 476.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
If we subtract 4653 from 5129, we get 476.
Fetch the next digit (3) from the dividend, attach it to 476 and continue: 4763 / 517

Let's proceed to step 6:
When dividing 4763 by 517, we get 9 with a remainder of 110.
Record the quotient 9 as the next digit in the result. 
Result so far: 399.0
Subtracting 4653 from 4763 leaves us with 110.
Take the next digit (4) from the dividend and append it to 110, then repeat: 1104 / 517

Step 7:
1104 divided by 517 is 2 with a remainder of 70.
Use 2 as the next digit of our solution. 
Result so far: 3992.0
Deduct 1034 from 1104 and we're left with 70.
Append the next digit (9) from the dividend to 70 and continue with: 709 / 517

Let's proceed to step 8:
The number 517 fits into 709 1 times, leaving a remainder of 192.
The next digit of our result is 1. 
Result so far: 39921.0
Deduct 517 from 709 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 9:
1920 divided by 517 is 3 with a remainder of 369.
Write down 3 as next digit of the result. 
Result so far: 39921.3
Deduct 1551 from 1920 and we're left with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Going ahead to step 10:
The number 517 fits into 3690 7 times, leaving a remainder of 71.
The number 7 becomes the next digit in our result. 
Result so far: 39921.37
Subtracting 3619 from 3690 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 11:
517 goes into 710 1 times with a remainder of 193.
Use 1 as the next digit of our solution. 
Result so far: 39921.371
Subtract 517 from 710 to get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

On to step 12:
If we divide 1930 by 517, we get 3 and a remainder of 379.
The number 3 becomes the next digit in our result. 
Result so far: 39921.3713
If we subtract 1551 from 1930, we get 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Advancing to step 13:
The number 517 fits into 3790 7 times, leaving a remainder of 171.
Write down 7 as next digit of the result. 
Result so far: 39921.37137
If we take 3619 away from 3790, we end up with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Let's proceed to step 14:
517 can be fit into 1710 3 times, resulting in a remainder of 159.
Use 3 as the next digit of our solution. 
Result so far: 39921.371373
Subtracting 1551 from 1710 leaves us with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

On to step 15:
If we divide 1590 by 517, we get 3 and a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 39921.3713733
Subtract 1551 from 1590 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

After the division, we end up with 39921.3713733 and a remainder of 3.9e-07.
