On to step 2:
The number 259 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Fetch the next digit (8) from the dividend, attach it to 80 and continue: 808 / 259

Going ahead to step 3:
808 divided by 259 is 3 with a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 777 from 808 leaves us with 31.
Take the next digit (3) from the dividend and append it to 31, then repeat: 313 / 259

259 can be fit into 313 1 times, resulting in a remainder of 54.
The next digit of our result is 1. 
Result so far: 31.0
The remainder is 54 after subtracting 259 from 313.
Fetch the next digit (0) from the dividend, attach it to 54 and continue: 540 / 259

Advancing to step 5:
540 divided by 259 is 2 with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 312.0
Subtracting 518 from 540 leaves us with 22.
Grab the next digit (0) from the dividend, add it to 22, then carry on: 220 / 259

Step 6:
The number 259 fits into 220 0 times, leaving a remainder of 220.
The next digit of our result is 0. 
Result so far: 3120.0
The remainder is 220 after subtracting 0 from 220.
Bring next digit (8) of the dividend behind the 220 and repeat the process: 2208 / 259

On to step 7:
If we divide 2208 by 259, we get 8 and a remainder of 136.
Use 8 as the next digit of our solution. 
Result so far: 31208.0
Subtract 2072 from 2208 to get 136.
Grab the next digit (8) from the dividend, add it to 136, then carry on: 1368 / 259

Going ahead to step 8:
If we divide 1368 by 259, we get 5 and a remainder of 73.
The next digit of our result is 5. 
Result so far: 312085.0
Deduct 1295 from 1368 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 9:
259 can be fit into 730 2 times, resulting in a remainder of 212.
Use 2 as the next digit of our solution. 
Result so far: 312085.2
Deduct 518 from 730 and we're left with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Let's proceed to step 10:
259 goes into 2120 8 times with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 312085.28
The remainder is 48 after subtracting 2072 from 2120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 11:
259 goes into 480 1 times with a remainder of 221.
The number 1 becomes the next digit in our result. 
Result so far: 312085.281
Subtracting 259 from 480 leaves us with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Step 12:
259 goes into 2210 8 times with a remainder of 138.
Write down 8 as next digit of the result. 
Result so far: 312085.2818
Subtract 2072 from 2210 to get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Moving on to step 13:
259 goes into 1380 5 times with a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 312085.28185
Deduct 1295 from 1380 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 14:
When dividing 850 by 259, we get 3 with a remainder of 73.
Record the quotient 3 as the next digit in the result. 
Result so far: 312085.281853
If we subtract 777 from 850, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 15:
259 goes into 730 2 times with a remainder of 212.
The next digit of our result is 2. 
Result so far: 312085.2818532
If we subtract 518 from 730, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Step 16:
The number 259 fits into 2120 8 times, leaving a remainder of 48.
The next digit of our result is 8. 
Result so far: 312085.28185328
Deduct 2072 from 2120 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Our division results in 312085.28185328 with a remaining 4.8e-08.
