78667313 divided by 391 
Our goal is to divide 78667313 by 391.

Advancing to step 1:
When dividing 7 by 391, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 391

On to step 2:
The number 391 fits into 78 0 times, leaving a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Fetch the next digit (6) from the dividend, attach it to 78 and continue: 786 / 391

Moving on to step 3:
786 divided by 391 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 782 from 786, we get 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 391

Moving on to step 4:
391 can be fit into 46 0 times, resulting in a remainder of 46.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtract 0 from 46 to get 46.
Take the next digit (7) from the dividend and append it to 46, then repeat: 467 / 391

Advancing to step 5:
391 can be fit into 467 1 times, resulting in a remainder of 76.
The number 1 becomes the next digit in our result. 
Result so far: 201.0
Subtracting 391 from 467 leaves us with 76.
Take the next digit (3) from the dividend and append it to 76, then repeat: 763 / 391

Moving on to step 6:
391 goes into 763 1 times with a remainder of 372.
The number 1 becomes the next digit in our result. 
Result so far: 2011.0
If we take 391 away from 763, we end up with 372.
Bring next digit (1) of the dividend behind the 372 and repeat the process: 3721 / 391

Going ahead to step 7:
391 goes into 3721 9 times with a remainder of 202.
Use 9 as the next digit of our solution. 
Result so far: 20119.0
Subtracting 3519 from 3721 leaves us with 202.
Include the next digit (3) from the dividend after 202, then repeat: 2023 / 391

Advancing to step 8:
If we divide 2023 by 391, we get 5 and a remainder of 68.
Write down 5 as next digit of the result. 
Result so far: 201195.0
If we take 1955 away from 2023, we end up 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.

Moving on to step 9:
391 goes into 680 1 times with a remainder of 289.
Use 1 as the next digit of our solution. 
Result so far: 201195.1
The remainder is 289 after subtracting 391 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Step 10:
When dividing 2890 by 391, we get 7 with a remainder of 153.
Put 7 as the next digit of the answer. 
Result so far: 201195.17
If we take 2737 away from 2890, we end up with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

On to step 11:
391 can be fit into 1530 3 times, resulting in a remainder of 357.
Write down 3 as next digit of the result. 
Result so far: 201195.173
The remainder is 357 after subtracting 1173 from 1530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Moving on to step 12:
391 can be fit into 3570 9 times, resulting in a remainder of 51.
The next digit of our result is 9. 
Result so far: 201195.1739
The remainder is 51 after subtracting 3519 from 3570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 13:
391 goes into 510 1 times with a remainder of 119.
The number 1 becomes the next digit in our result. 
Result so far: 201195.17391
Deduct 391 from 510 and we're left with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Moving on to step 14:
391 goes into 1190 3 times with a remainder of 17.
The next digit of our result is 3. 
Result so far: 201195.173913
Subtract 1173 from 1190 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 15:
When dividing 170 by 391, we get 0 with a remainder of 170.
Record the quotient 0 as the next digit in the result. 
Result so far: 201195.173913
Subtract 0 from 170 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 16:
391 can be fit into 1700 4 times, resulting in a remainder of 136.
The number 4 becomes the next digit in our result. 
Result so far: 201195.17391304
Subtracting 1564 from 1700 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

The final result is 201195.17391304 with a remainder of 1.36e-07.
