Let's divide 25396077 by 855
Let's see how many times 855 fits into 25396077.

Step 1:
The number 855 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 855

Let's proceed to step 2:
25 divided by 855 is 0 with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Append the next digit (3) from the dividend to 25 and continue with: 253 / 855

Moving on to step 3:
855 goes into 253 0 times with a remainder of 253.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 253 leaves us with 253.
Take the next digit (9) from the dividend and append it to 253, then repeat: 2539 / 855

Advancing to step 4:
855 goes into 2539 2 times with a remainder of 829.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 1710 from 2539 leaves us with 829.
Append the next digit (6) from the dividend to 829 and continue with: 8296 / 855

Going ahead to step 5:
8296 divided by 855 is 9 with a remainder of 601.
Put 9 as the next digit of the answer. 
Result so far: 29.0
If we subtract 7695 from 8296, we get 601.
Include the next digit (0) from the dividend after 601, then repeat: 6010 / 855

Going ahead to step 6:
855 can be fit into 6010 7 times, resulting in a remainder of 25.
The next digit of our result is 7. 
Result so far: 297.0
The remainder is 25 after subtracting 5985 from 6010.
Append the next digit (7) from the dividend to 25 and continue with: 257 / 855

Step 7:
When dividing 257 by 855, we get 0 with a remainder of 257.
Record the quotient 0 as the next digit in the result. 
Result so far: 2970.0
The remainder is 257 after subtracting 0 from 257.
Take the next digit (7) from the dividend and append it to 257, then repeat: 2577 / 855

On to step 8:
The number 855 fits into 2577 3 times, leaving a remainder of 12.
The next digit of our result is 3. 
Result so far: 29703.0
If we take 2565 away from 2577, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
When dividing 120 by 855, we get 0 with a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 29703.0
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 10:
If we divide 1200 by 855, we get 1 and a remainder of 345.
The next digit of our result is 1. 
Result so far: 29703.01
Deduct 855 from 1200 and we're left with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Let's proceed to step 11:
855 goes into 3450 4 times with a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 29703.014
If we subtract 3420 from 3450, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
When dividing 300 by 855, we get 0 with a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 29703.014
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 13:
855 goes into 3000 3 times with a remainder of 435.
Put 3 as the next digit of the answer. 
Result so far: 29703.01403
Subtracting 2565 from 3000 leaves us with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Let's proceed to step 14:
The number 855 fits into 4350 5 times, leaving a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 29703.014035
If we subtract 4275 from 4350, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 15:
The number 855 fits into 750 0 times, leaving a remainder of 750.
Put 0 as the next digit of the answer. 
Result so far: 29703.014035
The remainder is 750 after subtracting 0 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Moving on to step 16:
When dividing 7500 by 855, we get 8 with a remainder of 660.
The next digit of our result is 8. 
Result so far: 29703.01403508
Subtracting 6840 from 7500 leaves us with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

In conclusion, the division gives 29703.01403508 with a balance of 6.6e-07.
