21816324 ÷ 830 
Our goal is to divide 21816324 by 830.

Let's proceed to step 1:
When dividing 2 by 830, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 830

On to step 2:
The number 830 fits into 21 0 times, leaving a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 830

Going ahead to step 3:
When dividing 218 by 830, we get 0 with a remainder of 218.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 218 and we're left with 218.
Take the next digit (1) from the dividend and append it to 218, then repeat: 2181 / 830

Step 4:
The number 830 fits into 2181 2 times, leaving a remainder of 521.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 521 after subtracting 1660 from 2181.
Take the next digit (6) from the dividend and append it to 521, then repeat: 5216 / 830

Moving on to step 5:
830 goes into 5216 6 times with a remainder of 236.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
The remainder is 236 after subtracting 4980 from 5216.
Fetch the next digit (3) from the dividend, attach it to 236 and continue: 2363 / 830

Let's proceed to step 6:
The number 830 fits into 2363 2 times, leaving a remainder of 703.
Record the quotient 2 as the next digit in the result. 
Result so far: 262.0
The remainder is 703 after subtracting 1660 from 2363.
Append the next digit (2) from the dividend to 703 and continue with: 7032 / 830

On to step 7:
830 goes into 7032 8 times with a remainder of 392.
Put 8 as the next digit of the answer. 
Result so far: 2628.0
Subtracting 6640 from 7032 leaves us with 392.
Append the next digit (4) from the dividend to 392 and continue with: 3924 / 830

Let's proceed to step 8:
When dividing 3924 by 830, we get 4 with a remainder of 604.
Write down 4 as next digit of the result. 
Result so far: 26284.0
If we subtract 3320 from 3924, we get 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Moving on to step 9:
6040 divided by 830 is 7 with a remainder of 230.
Use 7 as the next digit of our solution. 
Result so far: 26284.7
The remainder is 230 after subtracting 5810 from 6040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 10:
2300 divided by 830 is 2 with a remainder of 640.
Record the quotient 2 as the next digit in the result. 
Result so far: 26284.72
The remainder is 640 after subtracting 1660 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 11:
When dividing 6400 by 830, we get 7 with a remainder of 590.
Write down 7 as next digit of the result. 
Result so far: 26284.727
Subtracting 5810 from 6400 leaves us with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

On to step 12:
830 goes into 5900 7 times with a remainder of 90.
The number 7 becomes the next digit in our result. 
Result so far: 26284.7277
The remainder is 90 after subtracting 5810 from 5900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

The final result is 26284.7277 with a remainder of 0.0009.
