Let's divide 86511349 by 259
We're looking to find how many times 259 goes into 86511349.

On to step 1:
259 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 259

On to step 2:
When dividing 86 by 259, we get 0 with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Include the next digit (5) from the dividend after 86, then repeat: 865 / 259

Advancing to step 3:
865 divided by 259 is 3 with a remainder of 88.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 777 from 865 and we're left with 88.
Include the next digit (1) from the dividend after 88, then repeat: 881 / 259

Moving on to step 4:
If we divide 881 by 259, we get 3 and a remainder of 104.
The next digit of our result is 3. 
Result so far: 33.0
Subtracting 777 from 881 leaves us with 104.
Fetch the next digit (1) from the dividend, attach it to 104 and continue: 1041 / 259

On to step 5:
259 can be fit into 1041 4 times, resulting in a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 334.0
If we take 1036 away from 1041, we end up with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 259

On to step 6:
259 goes into 53 0 times with a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 3340.0
If we take 0 away from 53, we end up with 53.
Grab the next digit (4) from the dividend, add it to 53, then carry on: 534 / 259

Going ahead to step 7:
259 can be fit into 534 2 times, resulting in a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 33402.0
Deduct 518 from 534 and we're left with 16.
Include the next digit (9) from the dividend after 16, then repeat: 169 / 259

Step 8:
259 goes into 169 0 times with a remainder of 169.
Write down 0 as next digit of the result. 
Result so far: 334020.0
Subtract 0 from 169 to get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Step 9:
259 can be fit into 1690 6 times, resulting in a remainder of 136.
Put 6 as the next digit of the answer. 
Result so far: 334020.6
If we subtract 1554 from 1690, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 10:
259 goes into 1360 5 times with a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 334020.65
Deduct 1295 from 1360 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 11:
When dividing 650 by 259, we get 2 with a remainder of 132.
The next digit of our result is 2. 
Result so far: 334020.652
The remainder is 132 after subtracting 518 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 12:
When dividing 1320 by 259, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 334020.6525
Subtract 1295 from 1320 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 13:
250 divided by 259 is 0 with a remainder of 250.
Use 0 as the next digit of our solution. 
Result so far: 334020.6525
If we take 0 away from 250, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 14:
2500 divided by 259 is 9 with a remainder of 169.
Put 9 as the next digit of the answer. 
Result so far: 334020.652509
If we subtract 2331 from 2500, we get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Advancing to step 15:
If we divide 1690 by 259, we get 6 and a remainder of 136.
Put 6 as the next digit of the answer. 
Result so far: 334020.6525096
If we take 1554 away from 1690, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 16:
If we divide 1360 by 259, we get 5 and a remainder of 65.
The next digit of our result is 5. 
Result so far: 334020.65250965
The remainder is 65 after subtracting 1295 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final result is 334020.65250965 with a remainder of 6.5e-08.
