Let's divide 20721316 by 829
We want to divide 20721316 by 829.

Advancing to step 1:
829 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 829

Step 2:
829 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Take the next digit (7) from the dividend and append it to 20, then repeat: 207 / 829

Step 3:
If we divide 207 by 829, we get 0 and a remainder of 207.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 207, we end up with 207.
Fetch the next digit (2) from the dividend, attach it to 207 and continue: 2072 / 829

Moving on to step 4:
829 goes into 2072 2 times with a remainder of 414.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 1658 from 2072 to get 414.
Fetch the next digit (1) from the dividend, attach it to 414 and continue: 4141 / 829

Going ahead to step 5:
829 goes into 4141 4 times with a remainder of 825.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
If we take 3316 away from 4141, we end up with 825.
Append the next digit (3) from the dividend to 825 and continue with: 8253 / 829

On to step 6:
829 goes into 8253 9 times with a remainder of 792.
Write down 9 as next digit of the result. 
Result so far: 249.0
If we subtract 7461 from 8253, we get 792.
Bring next digit (1) of the dividend behind the 792 and repeat the process: 7921 / 829

Moving on to step 7:
829 can be fit into 7921 9 times, resulting in a remainder of 460.
Use 9 as the next digit of our solution. 
Result so far: 2499.0
If we take 7461 away from 7921, we end up with 460.
Grab the next digit (6) from the dividend, add it to 460, then carry on: 4606 / 829

On to step 8:
When dividing 4606 by 829, we get 5 with a remainder of 461.
Use 5 as the next digit of our solution. 
Result so far: 24995.0
If we subtract 4145 from 4606, we get 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Advancing to step 9:
829 goes into 4610 5 times with a remainder of 465.
Write down 5 as next digit of the result. 
Result so far: 24995.5
If we subtract 4145 from 4610, we get 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

On to step 10:
If we divide 4650 by 829, we get 5 and a remainder of 505.
Record the quotient 5 as the next digit in the result. 
Result so far: 24995.55
Subtracting 4145 from 4650 leaves us with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Our division results in 24995.55 with a remaining 0.505.
