We look at the division of 78655314 by 391 
Our goal is to divide 78655314 by 391.

On to step 1:
7 divided by 391 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 391

Going ahead 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
If we subtract 0 from 78, we get 78.
Grab the next digit (6) from the dividend, add it to 78, then carry on: 786 / 391

Going ahead 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
Deduct 782 from 786 and we're left with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 391

On to step 4:
The number 391 fits into 45 0 times, leaving a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we subtract 0 from 45, we get 45.
Bring next digit (5) of the dividend behind the 45 and repeat the process: 455 / 391

Advancing to step 5:
The number 391 fits into 455 1 times, leaving a remainder of 64.
Use 1 as the next digit of our solution. 
Result so far: 201.0
The remainder is 64 after subtracting 391 from 455.
Append the next digit (3) from the dividend to 64 and continue with: 643 / 391

Let's proceed to step 6:
391 can be fit into 643 1 times, resulting in a remainder of 252.
The next digit of our result is 1. 
Result so far: 2011.0
The remainder is 252 after subtracting 391 from 643.
Take the next digit (1) from the dividend and append it to 252, then repeat: 2521 / 391

Step 7:
391 goes into 2521 6 times with a remainder of 175.
Write down 6 as next digit of the result. 
Result so far: 20116.0
Subtracting 2346 from 2521 leaves us with 175.
Fetch the next digit (4) from the dividend, attach it to 175 and continue: 1754 / 391

Step 8:
If we divide 1754 by 391, we get 4 and a remainder of 190.
Put 4 as the next digit of the answer. 
Result so far: 201164.0
The remainder is 190 after subtracting 1564 from 1754.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 9:
391 can be fit into 1900 4 times, resulting in a remainder of 336.
Put 4 as the next digit of the answer. 
Result so far: 201164.4
The remainder is 336 after subtracting 1564 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

On to step 10:
3360 divided by 391 is 8 with a remainder of 232.
The number 8 becomes the next digit in our result. 
Result so far: 201164.48
If we subtract 3128 from 3360, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Moving on to step 11:
391 can be fit into 2320 5 times, resulting in a remainder of 365.
The next digit of our result is 5. 
Result so far: 201164.485
Subtract 1955 from 2320 to get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Moving on to step 12:
The number 391 fits into 3650 9 times, leaving a remainder of 131.
The number 9 becomes the next digit in our result. 
Result so far: 201164.4859
Subtracting 3519 from 3650 leaves us with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Moving on to step 13:
When dividing 1310 by 391, we get 3 with a remainder of 137.
Put 3 as the next digit of the answer. 
Result so far: 201164.48593
If we take 1173 away from 1310, we end up with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Going ahead to step 14:
391 goes into 1370 3 times with a remainder of 197.
The next digit of our result is 3. 
Result so far: 201164.485933
If we take 1173 away from 1370, we end up with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

The quotient of the division is 201164.485933, and the remainder is 1.97e-05.
