We're dividing 5278863 by 391 
Let's see how many times 391 fits into 5278863.

Step 1:
391 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 391

Step 2:
391 goes into 52 0 times with a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Grab the next digit (7) from the dividend, add it to 52, then carry on: 527 / 391

On to step 3:
527 divided by 391 is 1 with a remainder of 136.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 136 after subtracting 391 from 527.
Include the next digit (8) from the dividend after 136, then repeat: 1368 / 391

Advancing to step 4:
The number 391 fits into 1368 3 times, leaving a remainder of 195.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 1173 from 1368 to get 195.
Fetch the next digit (8) from the dividend, attach it to 195 and continue: 1958 / 391

Advancing to step 5:
391 can be fit into 1958 5 times, resulting in a remainder of 3.
The next digit of our result is 5. 
Result so far: 135.0
The remainder is 3 after subtracting 1955 from 1958.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 391

Step 6:
391 can be fit into 36 0 times, resulting in a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 1350.0
Subtracting 0 from 36 leaves us with 36.
Take the next digit (3) from the dividend and append it to 36, then repeat: 363 / 391

Step 7:
391 can be fit into 363 0 times, resulting in a remainder of 363.
The next digit of our result is 0. 
Result so far: 13500.0
If we take 0 away from 363, we end up with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Advancing to step 8:
391 goes into 3630 9 times with a remainder of 111.
The number 9 becomes the next digit in our result. 
Result so far: 13500.9
Deduct 3519 from 3630 and we're left with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Moving on to step 9:
391 goes into 1110 2 times with a remainder of 328.
Record the quotient 2 as the next digit in the result. 
Result so far: 13500.92
Deduct 782 from 1110 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 10:
391 goes into 3280 8 times with a remainder of 152.
Use 8 as the next digit of our solution. 
Result so far: 13500.928
If we subtract 3128 from 3280, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 11:
391 goes into 1520 3 times with a remainder of 347.
Use 3 as the next digit of our solution. 
Result so far: 13500.9283
If we subtract 1173 from 1520, we get 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Advancing to step 12:
If we divide 3470 by 391, we get 8 and a remainder of 342.
Record the quotient 8 as the next digit in the result. 
Result so far: 13500.92838
Subtract 3128 from 3470 to get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Moving on to step 13:
The number 391 fits into 3420 8 times, leaving a remainder of 292.
Write down 8 as next digit of the result. 
Result so far: 13500.928388
The remainder is 292 after subtracting 3128 from 3420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

In conclusion, the division gives 13500.928388 with a balance of 2.92e-05.
