Let's divide 20494220 by 821
Let's see how many times 821 fits into 20494220.

Step 1:
821 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 821

On to step 2:
The number 821 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 821

Advancing to step 3:
821 can be fit into 204 0 times, resulting in a remainder of 204.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 204 to get 204.
Include the next digit (9) from the dividend after 204, then repeat: 2049 / 821

Going ahead to step 4:
If we divide 2049 by 821, we get 2 and a remainder of 407.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 407 after subtracting 1642 from 2049.
Append the next digit (4) from the dividend to 407 and continue with: 4074 / 821

Step 5:
821 can be fit into 4074 4 times, resulting in a remainder of 790.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
If we subtract 3284 from 4074, we get 790.
Fetch the next digit (2) from the dividend, attach it to 790 and continue: 7902 / 821

Advancing to step 6:
821 can be fit into 7902 9 times, resulting in a remainder of 513.
The number 9 becomes the next digit in our result. 
Result so far: 249.0
Subtracting 7389 from 7902 leaves us with 513.
Take the next digit (2) from the dividend and append it to 513, then repeat: 5132 / 821

Going ahead to step 7:
821 can be fit into 5132 6 times, resulting in a remainder of 206.
The number 6 becomes the next digit in our result. 
Result so far: 2496.0
If we take 4926 away from 5132, we end up with 206.
Grab the next digit (0) from the dividend, add it to 206, then carry on: 2060 / 821

On to step 8:
2060 divided by 821 is 2 with a remainder of 418.
Use 2 as the next digit of our solution. 
Result so far: 24962.0
Subtracting 1642 from 2060 leaves us with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

On to step 9:
When dividing 4180 by 821, we get 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 24962.5
If we subtract 4105 from 4180, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 10:
821 can be fit into 750 0 times, resulting in a remainder of 750.
The number 0 becomes the next digit in our result. 
Result so far: 24962.5
If we take 0 away from 750, we end up with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Going ahead to step 11:
If we divide 7500 by 821, we get 9 and a remainder of 111.
Use 9 as the next digit of our solution. 
Result so far: 24962.509
The remainder is 111 after subtracting 7389 from 7500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

On to step 12:
821 can be fit into 1110 1 times, resulting in a remainder of 289.
The next digit of our result is 1. 
Result so far: 24962.5091
Deduct 821 from 1110 and we're left with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Let's proceed to step 13:
821 can be fit into 2890 3 times, resulting in a remainder of 427.
The number 3 becomes the next digit in our result. 
Result so far: 24962.50913
The remainder is 427 after subtracting 2463 from 2890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

Going ahead to step 14:
When dividing 4270 by 821, we get 5 with a remainder of 165.
Use 5 as the next digit of our solution. 
Result so far: 24962.509135
If we take 4105 away from 4270, we end up with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Going ahead to step 15:
1650 divided by 821 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 24962.5091352
If we take 1642 away from 1650, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 16:
80 divided by 821 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 24962.5091352
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

After the division, we end up with 24962.5091352 and a remainder of 8e-08.
