21723280 divided by 323 
We want to figure out the number of times 21723280 can be divided by 323.

Let's proceed to step 1:
323 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
Subtract 0 from 2 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 323

On to step 2:
21 divided by 323 is 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 323

Going ahead to step 3:
If we divide 217 by 323, we get 0 and a remainder of 217.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 217 to get 217.
Fetch the next digit (2) from the dividend, attach it to 217 and continue: 2172 / 323

Advancing to step 4:
If we divide 2172 by 323, we get 6 and a remainder of 234.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 1938 from 2172 and we're left with 234.
Grab the next digit (3) from the dividend, add it to 234, then carry on: 2343 / 323

On to step 5:
If we divide 2343 by 323, we get 7 and a remainder of 82.
The next digit of our result is 7. 
Result so far: 67.0
Deduct 2261 from 2343 and we're left with 82.
Grab the next digit (2) from the dividend, add it to 82, then carry on: 822 / 323

Moving on to step 6:
822 divided by 323 is 2 with a remainder of 176.
Use 2 as the next digit of our solution. 
Result so far: 672.0
The remainder is 176 after subtracting 646 from 822.
Include the next digit (8) from the dividend after 176, then repeat: 1768 / 323

Advancing to step 7:
When dividing 1768 by 323, we get 5 with a remainder of 153.
Write down 5 as next digit of the result. 
Result so far: 6725.0
Deduct 1615 from 1768 and we're left with 153.
Append the next digit (0) from the dividend to 153 and continue with: 1530 / 323

Moving on to step 8:
1530 divided by 323 is 4 with a remainder of 238.
The number 4 becomes the next digit in our result. 
Result so far: 67254.0
Deduct 1292 from 1530 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 9:
323 can be fit into 2380 7 times, resulting in a remainder of 119.
Use 7 as the next digit of our solution. 
Result so far: 67254.7
Subtracting 2261 from 2380 leaves us with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Going ahead to step 10:
1190 divided by 323 is 3 with a remainder of 221.
Write down 3 as next digit of the result. 
Result so far: 67254.73
If we subtract 969 from 1190, we get 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

On to step 11:
323 goes into 2210 6 times with a remainder of 272.
Record the quotient 6 as the next digit in the result. 
Result so far: 67254.736
If we take 1938 away from 2210, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

On to step 12:
The number 323 fits into 2720 8 times, leaving a remainder of 136.
Record the quotient 8 as the next digit in the result. 
Result so far: 67254.7368
Deduct 2584 from 2720 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 13:
If we divide 1360 by 323, we get 4 and a remainder of 68.
The next digit of our result is 4. 
Result so far: 67254.73684
The remainder is 68 after subtracting 1292 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 14:
323 can be fit into 680 2 times, resulting in a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 67254.736842
The remainder is 34 after subtracting 646 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 15:
340 divided by 323 is 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 67254.7368421
If we take 323 away from 340, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 16:
323 goes into 170 0 times with a remainder of 170.
Use 0 as the next digit of our solution. 
Result so far: 67254.7368421
Deduct 0 from 170 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

In conclusion, the division gives 67254.7368421 with a balance of 1.7e-07.
