Let's divide 25814065 by 259
We want to divide 25814065 by 259.

Going ahead to step 1:
The number 259 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
If we take 0 away from 2, we end up with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 259

On to step 2:
25 divided by 259 is 0 with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Take the next digit (8) from the dividend and append it to 25, then repeat: 258 / 259

Moving on to step 3:
When dividing 258 by 259, we get 0 with a remainder of 258.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 258 leaves us with 258.
Bring next digit (1) of the dividend behind the 258 and repeat the process: 2581 / 259

On to step 4:
259 goes into 2581 9 times with a remainder of 250.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 2331 from 2581, we get 250.
Bring next digit (4) of the dividend behind the 250 and repeat the process: 2504 / 259

Advancing to step 5:
259 goes into 2504 9 times with a remainder of 173.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
If we take 2331 away from 2504, we end up with 173.
Include the next digit (0) from the dividend after 173, then repeat: 1730 / 259

Moving on to step 6:
1730 divided by 259 is 6 with a remainder of 176.
Record the quotient 6 as the next digit in the result. 
Result so far: 996.0
If we subtract 1554 from 1730, we get 176.
Append the next digit (6) from the dividend to 176 and continue with: 1766 / 259

Moving on to step 7:
The number 259 fits into 1766 6 times, leaving a remainder of 212.
The next digit of our result is 6. 
Result so far: 9966.0
Subtract 1554 from 1766 to get 212.
Take the next digit (5) from the dividend and append it to 212, then repeat: 2125 / 259

Moving on to step 8:
The number 259 fits into 2125 8 times, leaving a remainder of 53.
The next digit of our result is 8. 
Result so far: 99668.0
If we subtract 2072 from 2125, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 9:
The number 259 fits into 530 2 times, leaving a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 99668.2
Subtracting 518 from 530 leaves us 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.

Advancing to step 10:
If we divide 120 by 259, we get 0 and a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 99668.2
Subtract 0 from 120 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 11:
The number 259 fits into 1200 4 times, leaving a remainder of 164.
Record the quotient 4 as the next digit in the result. 
Result so far: 99668.204
Deduct 1036 from 1200 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Going ahead to step 12:
259 goes into 1640 6 times with a remainder of 86.
Put 6 as the next digit of the answer. 
Result so far: 99668.2046
Subtract 1554 from 1640 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 13:
259 goes into 860 3 times with a remainder of 83.
Record the quotient 3 as the next digit in the result. 
Result so far: 99668.20463
Deduct 777 from 860 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 14:
The number 259 fits into 830 3 times, leaving a remainder of 53.
Put 3 as the next digit of the answer. 
Result so far: 99668.204633
If we subtract 777 from 830, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

The final outcome is 99668.204633, with a leftover of 5.3e-06.
