67009827 divided by 821 
Our goal is to divide 67009827 by 821.

On to step 1:
When dividing 6 by 821, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 821

Advancing to step 2:
If we divide 67 by 821, we get 0 and a remainder of 67.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Include the next digit (0) from the dividend after 67, then repeat: 670 / 821

Advancing to step 3:
670 divided by 821 is 0 with a remainder of 670.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 670 after subtracting 0 from 670.
Grab the next digit (0) from the dividend, add it to 670, then carry on: 6700 / 821

Moving on to step 4:
821 can be fit into 6700 8 times, resulting in a remainder of 132.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 6568 from 6700 to get 132.
Fetch the next digit (9) from the dividend, attach it to 132 and continue: 1329 / 821

Going ahead to step 5:
The number 821 fits into 1329 1 times, leaving a remainder of 508.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
Subtract 821 from 1329 to get 508.
Take the next digit (8) from the dividend and append it to 508, then repeat: 5088 / 821

Let's proceed to step 6:
5088 divided by 821 is 6 with a remainder of 162.
Use 6 as the next digit of our solution. 
Result so far: 816.0
The remainder is 162 after subtracting 4926 from 5088.
Grab the next digit (2) from the dividend, add it to 162, then carry on: 1622 / 821

On to step 7:
1622 divided by 821 is 1 with a remainder of 801.
The number 1 becomes the next digit in our result. 
Result so far: 8161.0
The remainder is 801 after subtracting 821 from 1622.
Take the next digit (7) from the dividend and append it to 801, then repeat: 8017 / 821

Step 8:
821 can be fit into 8017 9 times, resulting in a remainder of 628.
Use 9 as the next digit of our solution. 
Result so far: 81619.0
If we take 7389 away from 8017, we end up with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Step 9:
821 goes into 6280 7 times with a remainder of 533.
Write down 7 as next digit of the result. 
Result so far: 81619.7
Deduct 5747 from 6280 and we're left with 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

On to step 10:
The number 821 fits into 5330 6 times, leaving a remainder of 404.
Use 6 as the next digit of our solution. 
Result so far: 81619.76
If we take 4926 away from 5330, we end up with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Moving on to step 11:
4040 divided by 821 is 4 with a remainder of 756.
The next digit of our result is 4. 
Result so far: 81619.764
Subtracting 3284 from 4040 leaves us with 756.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7560, and continue the process.

Going ahead to step 12:
When dividing 7560 by 821, we get 9 with a remainder of 171.
The next digit of our result is 9. 
Result so far: 81619.7649
The remainder is 171 after subtracting 7389 from 7560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

On to step 13:
821 goes into 1710 2 times with a remainder of 68.
Write down 2 as next digit of the result. 
Result so far: 81619.76492
Subtracting 1642 from 1710 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 14:
821 can be fit into 680 0 times, resulting in a remainder of 680.
Write down 0 as next digit of the result. 
Result so far: 81619.76492
The remainder is 680 after subtracting 0 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Let's proceed to step 15:
6800 divided by 821 is 8 with a remainder of 232.
Put 8 as the next digit of the answer. 
Result so far: 81619.7649208
If we take 6568 away from 6800, we end up with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Let's proceed to step 16:
2320 divided by 821 is 2 with a remainder of 678.
Use 2 as the next digit of our solution. 
Result so far: 81619.76492082
The remainder is 678 after subtracting 1642 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

The final outcome is 81619.76492082, with a leftover of 6.78e-07.
