65810439 ÷ 259 
We want to figure out the number of times 65810439 can be divided by 259.

Going ahead to step 1:
259 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 259

On to step 2:
259 goes into 65 0 times with a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Fetch the next digit (8) from the dividend, attach it to 65 and continue: 658 / 259

Going ahead to step 3:
259 goes into 658 2 times with a remainder of 140.
The next digit of our result is 2. 
Result so far: 2.0
If we take 518 away from 658, we end up with 140.
Bring next digit (1) of the dividend behind the 140 and repeat the process: 1401 / 259

Let's proceed to step 4:
1401 divided by 259 is 5 with a remainder of 106.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtract 1295 from 1401 to get 106.
Include the next digit (0) from the dividend after 106, then repeat: 1060 / 259

Let's proceed to step 5:
259 can be fit into 1060 4 times, resulting in a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 254.0
Subtract 1036 from 1060 to get 24.
Append the next digit (4) from the dividend to 24 and continue with: 244 / 259

Going ahead to step 6:
259 goes into 244 0 times with a remainder of 244.
The next digit of our result is 0. 
Result so far: 2540.0
The remainder is 244 after subtracting 0 from 244.
Include the next digit (3) from the dividend after 244, then repeat: 2443 / 259

Let's proceed to step 7:
When dividing 2443 by 259, we get 9 with a remainder of 112.
The next digit of our result is 9. 
Result so far: 25409.0
Subtracting 2331 from 2443 leaves us with 112.
Fetch the next digit (9) from the dividend, attach it to 112 and continue: 1129 / 259

Let's proceed to step 8:
If we divide 1129 by 259, we get 4 and a remainder of 93.
The number 4 becomes the next digit in our result. 
Result so far: 254094.0
The remainder is 93 after subtracting 1036 from 1129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Moving on to step 9:
If we divide 930 by 259, we get 3 and a remainder of 153.
The number 3 becomes the next digit in our result. 
Result so far: 254094.3
The remainder is 153 after subtracting 777 from 930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Moving on to step 10:
The number 259 fits into 1530 5 times, leaving a remainder of 235.
The number 5 becomes the next digit in our result. 
Result so far: 254094.35
If we subtract 1295 from 1530, we get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Advancing to step 11:
The number 259 fits into 2350 9 times, leaving a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 254094.359
Subtracting 2331 from 2350 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 12:
If we divide 190 by 259, we get 0 and a remainder of 190.
Use 0 as the next digit of our solution. 
Result so far: 254094.359
Deduct 0 from 190 and we're left with 190.
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 13:
259 goes into 1900 7 times with a remainder of 87.
Put 7 as the next digit of the answer. 
Result so far: 254094.35907
If we take 1813 away from 1900, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 14:
When dividing 870 by 259, we get 3 with a remainder of 93.
Write down 3 as next digit of the result. 
Result so far: 254094.359073
If we take 777 away from 870, we end up with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Moving on to step 15:
When dividing 930 by 259, we get 3 with a remainder of 153.
Use 3 as the next digit of our solution. 
Result so far: 254094.3590733
Subtracting 777 from 930 leaves us with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

The final result is 254094.3590733 with a remainder of 1.53e-06.
