Let's divide 20691269 by 821
We're looking to find how many times 821 goes into 20691269.

Step 1:
2 divided by 821 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 821

Step 2:
The number 821 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Bring next digit (6) of the dividend behind the 20 and repeat the process: 206 / 821

Let's proceed to step 3:
206 divided by 821 is 0 with a remainder of 206.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 206, we get 206.
Bring next digit (9) of the dividend behind the 206 and repeat the process: 2069 / 821

Moving on to step 4:
The number 821 fits into 2069 2 times, leaving a remainder of 427.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1642 from 2069 and we're left with 427.
Take the next digit (1) from the dividend and append it to 427, then repeat: 4271 / 821

On to step 5:
4271 divided by 821 is 5 with a remainder of 166.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Deduct 4105 from 4271 and we're left with 166.
Bring next digit (2) of the dividend behind the 166 and repeat the process: 1662 / 821

Let's proceed to step 6:
When dividing 1662 by 821, we get 2 with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 252.0
If we take 1642 away from 1662, we end up with 20.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 821

Going ahead to step 7:
When dividing 206 by 821, we get 0 with a remainder of 206.
The next digit of our result is 0. 
Result so far: 2520.0
The remainder is 206 after subtracting 0 from 206.
Grab the next digit (9) from the dividend, add it to 206, then carry on: 2069 / 821

Advancing to step 8:
2069 divided by 821 is 2 with a remainder of 427.
The next digit of our result is 2. 
Result so far: 25202.0
If we take 1642 away from 2069, we end up with 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

Step 9:
821 goes into 4270 5 times with a remainder of 165.
Write down 5 as next digit of the result. 
Result so far: 25202.5
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.

Moving on to step 10:
If we divide 1650 by 821, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 25202.52
Subtract 1642 from 1650 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
When dividing 80 by 821, we get 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 25202.52
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 12:
821 can be fit into 800 0 times, resulting in a remainder of 800.
Record the quotient 0 as the next digit in the result. 
Result so far: 25202.52
The remainder is 800 after subtracting 0 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

The final outcome is 25202.52, with a leftover of 0.008.
