We're dividing 24586939 by 821 
Our goal is to divide 24586939 by 821.

Moving on to step 1:
When dividing 2 by 821, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 821

Going ahead 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
Subtracting 0 from 24 leaves us with 24.
Take the next digit (5) from the dividend and append it to 24, then repeat: 245 / 821

Let's proceed to step 3:
When dividing 245 by 821, we get 0 with a remainder of 245.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 245, we end up with 245.
Fetch the next digit (8) from the dividend, attach it to 245 and continue: 2458 / 821

Advancing to step 4:
The number 821 fits into 2458 2 times, leaving a remainder of 816.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 816 after subtracting 1642 from 2458.
Grab the next digit (6) from the dividend, add it to 816, then carry on: 8166 / 821

Step 5:
If we divide 8166 by 821, we get 9 and a remainder of 777.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
If we subtract 7389 from 8166, we get 777.
Bring next digit (9) of the dividend behind the 777 and repeat the process: 7779 / 821

On to step 6:
821 goes into 7779 9 times with a remainder of 390.
Record the quotient 9 as the next digit in the result. 
Result so far: 299.0
The remainder is 390 after subtracting 7389 from 7779.
Include the next digit (3) from the dividend after 390, then repeat: 3903 / 821

Going ahead to step 7:
If we divide 3903 by 821, we get 4 and a remainder of 619.
Write down 4 as next digit of the result. 
Result so far: 2994.0
The remainder is 619 after subtracting 3284 from 3903.
Grab the next digit (9) from the dividend, add it to 619, then carry on: 6199 / 821

On to step 8:
821 goes into 6199 7 times with a remainder of 452.
The number 7 becomes the next digit in our result. 
Result so far: 29947.0
If we take 5747 away from 6199, we end up with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

On to step 9:
821 can be fit into 4520 5 times, resulting in a remainder of 415.
The number 5 becomes the next digit in our result. 
Result so far: 29947.5
Subtracting 4105 from 4520 leaves us with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Advancing to step 10:
821 goes into 4150 5 times with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 29947.55
If we subtract 4105 from 4150, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The quotient of the division is 29947.55, and the remainder is 0.045.
