21028065 divided by 723 
Let's see how many times 723 fits into 21028065.

On to step 1:
The number 723 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 723

On to step 2:
When dividing 21 by 723, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 723

Let's proceed to step 3:
723 goes into 210 0 times with a remainder of 210.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 210, we end up with 210.
Grab the next digit (2) from the dividend, add it to 210, then carry on: 2102 / 723

Step 4:
723 can be fit into 2102 2 times, resulting in a remainder of 656.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 1446 from 2102, we get 656.
Fetch the next digit (8) from the dividend, attach it to 656 and continue: 6568 / 723

Going ahead to step 5:
723 goes into 6568 9 times with a remainder of 61.
Use 9 as the next digit of our solution. 
Result so far: 29.0
If we subtract 6507 from 6568, we get 61.
Include the next digit (0) from the dividend after 61, then repeat: 610 / 723

Going ahead to step 6:
723 goes into 610 0 times with a remainder of 610.
The next digit of our result is 0. 
Result so far: 290.0
If we take 0 away from 610, we end up with 610.
Fetch the next digit (6) from the dividend, attach it to 610 and continue: 6106 / 723

Step 7:
If we divide 6106 by 723, we get 8 and a remainder of 322.
Use 8 as the next digit of our solution. 
Result so far: 2908.0
Subtracting 5784 from 6106 leaves us with 322.
Bring next digit (5) of the dividend behind the 322 and repeat the process: 3225 / 723

Going ahead to step 8:
723 can be fit into 3225 4 times, resulting in a remainder of 333.
Use 4 as the next digit of our solution. 
Result so far: 29084.0
If we subtract 2892 from 3225, we get 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Advancing to step 9:
723 goes into 3330 4 times with a remainder of 438.
Put 4 as the next digit of the answer. 
Result so far: 29084.4
Subtracting 2892 from 3330 leaves us with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Let's proceed to step 10:
723 can be fit into 4380 6 times, resulting in a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 29084.46
The remainder is 42 after subtracting 4338 from 4380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 11:
723 goes into 420 0 times with a remainder of 420.
The next digit of our result is 0. 
Result so far: 29084.46
If we take 0 away from 420, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 12:
723 goes into 4200 5 times with a remainder of 585.
Put 5 as the next digit of the answer. 
Result so far: 29084.4605
Subtracting 3615 from 4200 leaves us with 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Going ahead to step 13:
The number 723 fits into 5850 8 times, leaving a remainder of 66.
Record the quotient 8 as the next digit in the result. 
Result so far: 29084.46058
Subtracting 5784 from 5850 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 14:
723 can be fit into 660 0 times, resulting in a remainder of 660.
Use 0 as the next digit of our solution. 
Result so far: 29084.46058
If we subtract 0 from 660, we get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

On to step 15:
The number 723 fits into 6600 9 times, leaving a remainder of 93.
The number 9 becomes the next digit in our result. 
Result so far: 29084.4605809
Deduct 6507 from 6600 and we're left with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Moving on to step 16:
723 goes into 930 1 times with a remainder of 207.
Put 1 as the next digit of the answer. 
Result so far: 29084.46058091
Subtract 723 from 930 to get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

The final result is 29084.46058091 with a remainder of 2.07e-07.
