21392993 ÷ 520 
Let's see how many times 520 fits into 21392993.

Let's proceed to step 1:
520 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.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 520

On to step 2:
520 can be fit into 21 0 times, resulting in a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 520

Step 3:
If we divide 213 by 520, we get 0 and a remainder of 213.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 213, we end up with 213.
Append the next digit (9) from the dividend to 213 and continue with: 2139 / 520

On to step 4:
The number 520 fits into 2139 4 times, leaving a remainder of 59.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 59 after subtracting 2080 from 2139.
Include the next digit (2) from the dividend after 59, then repeat: 592 / 520

Going ahead to step 5:
The number 520 fits into 592 1 times, leaving a remainder of 72.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Subtract 520 from 592 to get 72.
Append the next digit (9) from the dividend to 72 and continue with: 729 / 520

Going ahead to step 6:
When dividing 729 by 520, we get 1 with a remainder of 209.
Put 1 as the next digit of the answer. 
Result so far: 411.0
The remainder is 209 after subtracting 520 from 729.
Take the next digit (9) from the dividend and append it to 209, then repeat: 2099 / 520

Advancing to step 7:
The number 520 fits into 2099 4 times, leaving a remainder of 19.
Write down 4 as next digit of the result. 
Result so far: 4114.0
Subtracting 2080 from 2099 leaves us with 19.
Append the next digit (3) from the dividend to 19 and continue with: 193 / 520

Going ahead to step 8:
520 can be fit into 193 0 times, resulting in a remainder of 193.
Write down 0 as next digit of the result. 
Result so far: 41140.0
The remainder is 193 after subtracting 0 from 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 9:
When dividing 1930 by 520, we get 3 with a remainder of 370.
Write down 3 as next digit of the result. 
Result so far: 41140.3
If we take 1560 away from 1930, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Step 10:
3700 divided by 520 is 7 with a remainder of 60.
Write down 7 as next digit of the result. 
Result so far: 41140.37
Deduct 3640 from 3700 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
600 divided by 520 is 1 with a remainder of 80.
The number 1 becomes the next digit in our result. 
Result so far: 41140.371
Subtracting 520 from 600 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 12:
The number 520 fits into 800 1 times, leaving a remainder of 280.
Record the quotient 1 as the next digit in the result. 
Result so far: 41140.3711
Subtract 520 from 800 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The quotient of the division is 41140.3711, and the remainder is 0.0028.
