Let's divide 24993603 by 821
Our goal is to divide 24993603 by 821.

Going ahead to step 1:
The number 821 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 821

Moving on to step 2:
The number 821 fits into 24 0 times, leaving a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 24, we get 24.
Bring next digit (9) of the dividend behind the 24 and repeat the process: 249 / 821

Advancing to step 3:
249 divided by 821 is 0 with a remainder of 249.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 249 leaves us with 249.
Grab the next digit (9) from the dividend, add it to 249, then carry on: 2499 / 821

Step 4:
If we divide 2499 by 821, we get 3 and a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 36 after subtracting 2463 from 2499.
Grab the next digit (3) from the dividend, add it to 36, then carry on: 363 / 821

On to step 5:
821 goes into 363 0 times with a remainder of 363.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
If we subtract 0 from 363, we get 363.
Grab the next digit (6) from the dividend, add it to 363, then carry on: 3636 / 821

Going ahead to step 6:
3636 divided by 821 is 4 with a remainder of 352.
The next digit of our result is 4. 
Result so far: 304.0
Deduct 3284 from 3636 and we're left with 352.
Fetch the next digit (0) from the dividend, attach it to 352 and continue: 3520 / 821

Step 7:
If we divide 3520 by 821, we get 4 and a remainder of 236.
Write down 4 as next digit of the result. 
Result so far: 3044.0
If we subtract 3284 from 3520, we get 236.
Fetch the next digit (3) from the dividend, attach it to 236 and continue: 2363 / 821

Moving on to step 8:
821 goes into 2363 2 times with a remainder of 721.
Put 2 as the next digit of the answer. 
Result so far: 30442.0
The remainder is 721 after subtracting 1642 from 2363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7210, and continue the process.

On to step 9:
821 goes into 7210 8 times with a remainder of 642.
Write down 8 as next digit of the result. 
Result so far: 30442.8
Deduct 6568 from 7210 and we're left with 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

On to step 10:
The number 821 fits into 6420 7 times, leaving a remainder of 673.
Write down 7 as next digit of the result. 
Result so far: 30442.87
If we take 5747 away from 6420, we end up with 673.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6730, and continue the process.

Going ahead to step 11:
821 goes into 6730 8 times with a remainder of 162.
The number 8 becomes the next digit in our result. 
Result so far: 30442.878
The remainder is 162 after subtracting 6568 from 6730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Going ahead to step 12:
The number 821 fits into 1620 1 times, leaving a remainder of 799.
Put 1 as the next digit of the answer. 
Result so far: 30442.8781
If we subtract 821 from 1620, we get 799.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7990, and continue the process.

On to step 13:
If we divide 7990 by 821, we get 9 and a remainder of 601.
The number 9 becomes the next digit in our result. 
Result so far: 30442.87819
If we take 7389 away from 7990, we end up with 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

Advancing to step 14:
If we divide 6010 by 821, we get 7 and a remainder of 263.
Put 7 as the next digit of the answer. 
Result so far: 30442.878197
Deduct 5747 from 6010 and we're left with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Advancing to step 15:
When dividing 2630 by 821, we get 3 with a remainder of 167.
Write down 3 as next digit of the result. 
Result so far: 30442.8781973
If we subtract 2463 from 2630, we get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Going ahead to step 16:
When dividing 1670 by 821, we get 2 with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 30442.87819732
Subtract 1642 from 1670 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Our division results in 30442.87819732 with a remaining 2.8e-08.
