Step 4:
If we divide 2465 by 309, we get 7 and a remainder of 302.
Write down 7 as next digit of the result. 
Result so far: 27.0
If we take 2163 away from 2465, we end up with 302.
Take the next digit (2) from the dividend and append it to 302, then repeat: 3022 / 309

On to step 5:
When dividing 3022 by 309, we get 9 with a remainder of 241.
Use 9 as the next digit of our solution. 
Result so far: 279.0
Deduct 2781 from 3022 and we're left with 241.
Bring next digit (3) of the dividend behind the 241 and repeat the process: 2413 / 309

Advancing to step 6:
When dividing 2413 by 309, we get 7 with a remainder of 250.
The number 7 becomes the next digit in our result. 
Result so far: 2797.0
If we take 2163 away from 2413, we end up with 250.
Fetch the next digit (0) from the dividend, attach it to 250 and continue: 2500 / 309

Step 7:
309 goes into 2500 8 times with a remainder of 28.
The next digit of our result is 8. 
Result so far: 27978.0
Deduct 2472 from 2500 and we're left with 28.
Bring next digit (4) of the dividend behind the 28 and repeat the process: 284 / 309

Moving on to step 8:
284 divided by 309 is 0 with a remainder of 284.
Write down 0 as next digit of the result. 
Result so far: 279780.0
Deduct 0 from 284 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Step 9:
If we divide 2840 by 309, we get 9 and a remainder of 59.
The number 9 becomes the next digit in our result. 
Result so far: 279780.9
Subtracting 2781 from 2840 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 10:
590 divided by 309 is 1 with a remainder of 281.
Use 1 as the next digit of our solution. 
Result so far: 279780.91
Subtract 309 from 590 to get 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Step 11:
309 goes into 2810 9 times with a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 279780.919
Deduct 2781 from 2810 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 12:
The number 309 fits into 290 0 times, leaving a remainder of 290.
Record the quotient 0 as the next digit in the result. 
Result so far: 279780.919
The remainder is 290 after subtracting 0 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 13:
2900 divided by 309 is 9 with a remainder of 119.
Put 9 as the next digit of the answer. 
Result so far: 279780.91909
Deduct 2781 from 2900 and we're left with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Step 14:
309 goes into 1190 3 times with a remainder of 263.
Use 3 as the next digit of our solution. 
Result so far: 279780.919093
Subtracting 927 from 1190 leaves us with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Let's proceed to step 15:
309 can be fit into 2630 8 times, resulting in a remainder of 158.
The next digit of our result is 8. 
Result so far: 279780.9190938
If we take 2472 away from 2630, we end up with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Advancing to step 16:
When dividing 1580 by 309, we get 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 279780.91909385
The remainder is 35 after subtracting 1545 from 1580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Our division results in 279780.91909385 with a remaining 3.5e-08.
