We divide 21529816 by 490
We want to divide 21529816 by 490.

Advancing to step 1:
When dividing 2 by 490, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 490

Advancing to step 2:
21 divided by 490 is 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 490

Step 3:
If we divide 215 by 490, we get 0 and a remainder of 215.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 215, we get 215.
Include the next digit (2) from the dividend after 215, then repeat: 2152 / 490

Going ahead to step 4:
If we divide 2152 by 490, we get 4 and a remainder of 192.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 1960 from 2152 leaves us with 192.
Take the next digit (9) from the dividend and append it to 192, then repeat: 1929 / 490

Moving on to step 5:
1929 divided by 490 is 3 with a remainder of 459.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Subtracting 1470 from 1929 leaves us with 459.
Fetch the next digit (8) from the dividend, attach it to 459 and continue: 4598 / 490

Step 6:
4598 divided by 490 is 9 with a remainder of 188.
Record the quotient 9 as the next digit in the result. 
Result so far: 439.0
If we take 4410 away from 4598, we end up with 188.
Fetch the next digit (1) from the dividend, attach it to 188 and continue: 1881 / 490

Going ahead to step 7:
The number 490 fits into 1881 3 times, leaving a remainder of 411.
Use 3 as the next digit of our solution. 
Result so far: 4393.0
The remainder is 411 after subtracting 1470 from 1881.
Bring next digit (6) of the dividend behind the 411 and repeat the process: 4116 / 490

On to step 8:
When dividing 4116 by 490, we get 8 with a remainder of 196.
Record the quotient 8 as the next digit in the result. 
Result so far: 43938.0
Subtract 3920 from 4116 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

On to step 9:
1960 divided by 490 is 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 43938.4
If we subtract 1960 from 1960, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
If we divide 0 by 490, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 43938.4
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
490 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 43938.4
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 43938.4 with a remaining 0.0.
