2052503 divided by 821 
We want to divide 2052503 by 821.

Let's proceed to step 1:
If we divide 2 by 821, we get 0 and 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.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 821

Let's proceed to step 2:
821 goes into 20 0 times with 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.
Fetch the next digit (5) from the dividend, attach it to 20 and continue: 205 / 821

Advancing to step 3:
If we divide 205 by 821, we get 0 and a remainder of 205.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 205 after subtracting 0 from 205.
Append the next digit (2) from the dividend to 205 and continue with: 2052 / 821

On to step 4:
2052 divided by 821 is 2 with a remainder of 410.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 1642 from 2052 leaves us with 410.
Fetch the next digit (5) from the dividend, attach it to 410 and continue: 4105 / 821

Let's proceed to step 5:
821 can be fit into 4105 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Deduct 4105 from 4105 and we're left with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 821

Let's proceed to step 6:
The number 821 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 250.0
Subtract 0 from 0 to get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 821

Advancing to step 7:
If we divide 3 by 821, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 2500.0
Subtracting 0 from 3 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 8:
821 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 2500.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
821 can be fit into 300 0 times, resulting in a remainder of 300.
The next digit of our result is 0. 
Result so far: 2500.0
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final result is 2500.0 with a remainder of 0.3.
