68378797 ÷ 821 
We want to figure out the number of times 68378797 can be divided by 821.

Advancing to step 1:
821 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 821

Step 2:
821 goes into 68 0 times with a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Take the next digit (3) from the dividend and append it to 68, then repeat: 683 / 821

Going ahead to step 3:
683 divided by 821 is 0 with a remainder of 683.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 683, we get 683.
Grab the next digit (7) from the dividend, add it to 683, then carry on: 6837 / 821

Advancing to step 4:
When dividing 6837 by 821, we get 8 with a remainder of 269.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 269 after subtracting 6568 from 6837.
Grab the next digit (8) from the dividend, add it to 269, then carry on: 2698 / 821

Going ahead to step 5:
The number 821 fits into 2698 3 times, leaving a remainder of 235.
Put 3 as the next digit of the answer. 
Result so far: 83.0
If we subtract 2463 from 2698, we get 235.
Include the next digit (7) from the dividend after 235, then repeat: 2357 / 821

On to step 6:
2357 divided by 821 is 2 with a remainder of 715.
Put 2 as the next digit of the answer. 
Result so far: 832.0
Subtract 1642 from 2357 to get 715.
Append the next digit (9) from the dividend to 715 and continue with: 7159 / 821

Going ahead to step 7:
If we divide 7159 by 821, we get 8 and a remainder of 591.
The next digit of our result is 8. 
Result so far: 8328.0
The remainder is 591 after subtracting 6568 from 7159.
Fetch the next digit (7) from the dividend, attach it to 591 and continue: 5917 / 821

Step 8:
821 goes into 5917 7 times with a remainder of 170.
The number 7 becomes the next digit in our result. 
Result so far: 83287.0
Subtracting 5747 from 5917 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 9:
1700 divided by 821 is 2 with a remainder of 58.
The next digit of our result is 2. 
Result so far: 83287.2
Deduct 1642 from 1700 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 10:
821 can be fit into 580 0 times, resulting in a remainder of 580.
Put 0 as the next digit of the answer. 
Result so far: 83287.2
If we subtract 0 from 580, we get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Advancing to step 11:
When dividing 5800 by 821, we get 7 with a remainder of 53.
The next digit of our result is 7. 
Result so far: 83287.207
Subtract 5747 from 5800 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 12:
530 divided by 821 is 0 with a remainder of 530.
Write down 0 as next digit of the result. 
Result so far: 83287.207
Subtracting 0 from 530 leaves us with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Advancing to step 13:
When dividing 5300 by 821, we get 6 with a remainder of 374.
Put 6 as the next digit of the answer. 
Result so far: 83287.20706
Subtract 4926 from 5300 to get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Step 14:
3740 divided by 821 is 4 with a remainder of 456.
Write down 4 as next digit of the result. 
Result so far: 83287.207064
Subtracting 3284 from 3740 leaves us with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

On to step 15:
821 can be fit into 4560 5 times, resulting in a remainder of 455.
Write down 5 as next digit of the result. 
Result so far: 83287.2070645
Subtract 4105 from 4560 to get 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Step 16:
821 goes into 4550 5 times with a remainder of 445.
Use 5 as the next digit of our solution. 
Result so far: 83287.20706455
Subtracting 4105 from 4550 leaves us with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

The final outcome is 83287.20706455, with a leftover of 4.45e-07.
