We divide 21040889 by 519
We want to figure out the number of times 21040889 can be divided by 519.

On to step 1:
If we divide 2 by 519, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 519

Advancing to step 2:
The number 519 fits into 21 0 times, leaving a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 519

Let's proceed to step 3:
519 goes into 210 0 times with a remainder of 210.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 210 after subtracting 0 from 210.
Bring next digit (4) of the dividend behind the 210 and repeat the process: 2104 / 519

Moving on to step 4:
519 can be fit into 2104 4 times, resulting in a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 28 after subtracting 2076 from 2104.
Bring next digit (0) of the dividend behind the 28 and repeat the process: 280 / 519

Step 5:
519 can be fit into 280 0 times, resulting in a remainder of 280.
Put 0 as the next digit of the answer. 
Result so far: 40.0
The remainder is 280 after subtracting 0 from 280.
Fetch the next digit (8) from the dividend, attach it to 280 and continue: 2808 / 519

Moving on to step 6:
The number 519 fits into 2808 5 times, leaving a remainder of 213.
Put 5 as the next digit of the answer. 
Result so far: 405.0
Subtracting 2595 from 2808 leaves us with 213.
Bring next digit (8) of the dividend behind the 213 and repeat the process: 2138 / 519

Step 7:
When dividing 2138 by 519, we get 4 with a remainder of 62.
Write down 4 as next digit of the result. 
Result so far: 4054.0
If we take 2076 away from 2138, we end up with 62.
Grab the next digit (9) from the dividend, add it to 62, then carry on: 629 / 519

Going ahead to step 8:
519 can be fit into 629 1 times, resulting in a remainder of 110.
Write down 1 as next digit of the result. 
Result so far: 40541.0
The remainder is 110 after subtracting 519 from 629.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 9:
When dividing 1100 by 519, we get 2 with a remainder of 62.
The number 2 becomes the next digit in our result. 
Result so far: 40541.2
Subtracting 1038 from 1100 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 10:
The number 519 fits into 620 1 times, leaving a remainder of 101.
Write down 1 as next digit of the result. 
Result so far: 40541.21
Subtract 519 from 620 to get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Advancing to step 11:
519 goes into 1010 1 times with a remainder of 491.
Write down 1 as next digit of the result. 
Result so far: 40541.211
Deduct 519 from 1010 and we're left with 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Our division results in 40541.211 with a remaining 0.0491.
