We look at the division of 27956834 by 821 
We want to divide 27956834 by 821.

Advancing to step 1:
When dividing 2 by 821, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 821

On to step 2:
If we divide 27 by 821, we get 0 and a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 27 and we're left with 27.
Bring next digit (9) of the dividend behind the 27 and repeat the process: 279 / 821

Advancing to step 3:
821 can be fit into 279 0 times, resulting in a remainder of 279.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 279, we end up with 279.
Include the next digit (5) from the dividend after 279, then repeat: 2795 / 821

Going ahead to step 4:
The number 821 fits into 2795 3 times, leaving a remainder of 332.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 332 after subtracting 2463 from 2795.
Take the next digit (6) from the dividend and append it to 332, then repeat: 3326 / 821

Let's proceed to step 5:
The number 821 fits into 3326 4 times, leaving a remainder of 42.
The next digit of our result is 4. 
Result so far: 34.0
The remainder is 42 after subtracting 3284 from 3326.
Append the next digit (8) from the dividend to 42 and continue with: 428 / 821

Step 6:
When dividing 428 by 821, we get 0 with a remainder of 428.
Put 0 as the next digit of the answer. 
Result so far: 340.0
If we take 0 away from 428, we end up with 428.
Take the next digit (3) from the dividend and append it to 428, then repeat: 4283 / 821

Advancing to step 7:
If we divide 4283 by 821, we get 5 and a remainder of 178.
The next digit of our result is 5. 
Result so far: 3405.0
Subtract 4105 from 4283 to get 178.
Take the next digit (4) from the dividend and append it to 178, then repeat: 1784 / 821

On to step 8:
1784 divided by 821 is 2 with a remainder of 142.
The next digit of our result is 2. 
Result so far: 34052.0
Subtracting 1642 from 1784 leaves us with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Advancing to step 9:
When dividing 1420 by 821, we get 1 with a remainder of 599.
Put 1 as the next digit of the answer. 
Result so far: 34052.1
Deduct 821 from 1420 and we're left with 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

Advancing to step 10:
821 goes into 5990 7 times with a remainder of 243.
The number 7 becomes the next digit in our result. 
Result so far: 34052.17
Subtract 5747 from 5990 to get 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Advancing to step 11:
The number 821 fits into 2430 2 times, leaving a remainder of 788.
The number 2 becomes the next digit in our result. 
Result so far: 34052.172
Subtract 1642 from 2430 to get 788.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7880, and continue the process.

Going ahead to step 12:
The number 821 fits into 7880 9 times, leaving a remainder of 491.
The next digit of our result is 9. 
Result so far: 34052.1729
Subtract 7389 from 7880 to get 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

On to step 13:
821 goes into 4910 5 times with a remainder of 805.
Put 5 as the next digit of the answer. 
Result so far: 34052.17295
If we subtract 4105 from 4910, we get 805.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8050, and continue the process.

On to step 14:
The number 821 fits into 8050 9 times, leaving a remainder of 661.
Write down 9 as next digit of the result. 
Result so far: 34052.172959
If we take 7389 away from 8050, we end up with 661.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6610, and continue the process.

Going ahead to step 15:
When dividing 6610 by 821, we get 8 with a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 34052.1729598
Subtract 6568 from 6610 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 16:
420 divided by 821 is 0 with a remainder of 420.
The number 0 becomes the next digit in our result. 
Result so far: 34052.1729598
If we take 0 away from 420, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

The final outcome is 34052.1729598, with a leftover of 4.2e-07.
