25601377 divided by 391 
Let's see how many times 391 fits into 25601377.

Going ahead to step 1:
391 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 391

Moving on to step 2:
When dividing 25 by 391, we get 0 with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Include the next digit (6) from the dividend after 25, then repeat: 256 / 391

On to step 3:
When dividing 256 by 391, we get 0 with a remainder of 256.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 256 after subtracting 0 from 256.
Include the next digit (0) from the dividend after 256, then repeat: 2560 / 391

On to step 4:
2560 divided by 391 is 6 with a remainder of 214.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 2346 away from 2560, we end up with 214.
Append the next digit (1) from the dividend to 214 and continue with: 2141 / 391

Let's proceed to step 5:
391 goes into 2141 5 times with a remainder of 186.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
If we subtract 1955 from 2141, we get 186.
Append the next digit (3) from the dividend to 186 and continue with: 1863 / 391

Let's proceed to step 6:
When dividing 1863 by 391, we get 4 with a remainder of 299.
The number 4 becomes the next digit in our result. 
Result so far: 654.0
Subtract 1564 from 1863 to get 299.
Bring next digit (7) of the dividend behind the 299 and repeat the process: 2997 / 391

Moving on to step 7:
The number 391 fits into 2997 7 times, leaving a remainder of 260.
The number 7 becomes the next digit in our result. 
Result so far: 6547.0
Subtracting 2737 from 2997 leaves us with 260.
Grab the next digit (7) from the dividend, add it to 260, then carry on: 2607 / 391

Let's proceed to step 8:
If we divide 2607 by 391, we get 6 and a remainder of 261.
Write down 6 as next digit of the result. 
Result so far: 65476.0
Deduct 2346 from 2607 and we're left with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Step 9:
391 can be fit into 2610 6 times, resulting in a remainder of 264.
Record the quotient 6 as the next digit in the result. 
Result so far: 65476.6
Subtracting 2346 from 2610 leaves us with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Moving on to step 10:
When dividing 2640 by 391, we get 6 with a remainder of 294.
Put 6 as the next digit of the answer. 
Result so far: 65476.66
If we subtract 2346 from 2640, we get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

After the division, we end up with 65476.66 and a remainder of 0.294.
