If we divide 2 by 305, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 305

Moving on to step 2:
28 divided by 305 is 0 with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Bring next digit (4) of the dividend behind the 28 and repeat the process: 284 / 305

Moving on to step 3:
When dividing 284 by 305, we get 0 with a remainder of 284.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 284 to get 284.
Append the next digit (7) from the dividend to 284 and continue with: 2847 / 305

Advancing to step 4:
2847 divided by 305 is 9 with a remainder of 102.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 2745 from 2847 and we're left with 102.
Bring next digit (3) of the dividend behind the 102 and repeat the process: 1023 / 305

On to step 5:
305 can be fit into 1023 3 times, resulting in a remainder of 108.
Put 3 as the next digit of the answer. 
Result so far: 93.0
If we subtract 915 from 1023, we get 108.
Fetch the next digit (9) from the dividend, attach it to 108 and continue: 1089 / 305

Advancing to step 6:
When dividing 1089 by 305, we get 3 with a remainder of 174.
Use 3 as the next digit of our solution. 
Result so far: 933.0
If we take 915 away from 1089, we end up with 174.
Fetch the next digit (7) from the dividend, attach it to 174 and continue: 1747 / 305

Going ahead to step 7:
When dividing 1747 by 305, we get 5 with a remainder of 222.
The next digit of our result is 5. 
Result so far: 9335.0
The remainder is 222 after subtracting 1525 from 1747.
Append the next digit (8) from the dividend to 222 and continue with: 2228 / 305

Going ahead to step 8:
305 goes into 2228 7 times with a remainder of 93.
Write down 7 as next digit of the result. 
Result so far: 93357.0
Subtract 2135 from 2228 to get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Advancing to step 9:
305 goes into 930 3 times with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 93357.3
Deduct 915 from 930 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 10:
305 goes into 150 0 times with a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 93357.3
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 11:
1500 divided by 305 is 4 with a remainder of 280.
Put 4 as the next digit of the answer. 
Result so far: 93357.304
The remainder is 280 after subtracting 1220 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 12:
2800 divided by 305 is 9 with a remainder of 55.
Record the quotient 9 as the next digit in the result. 
Result so far: 93357.3049
Subtract 2745 from 2800 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 13:
305 can be fit into 550 1 times, resulting in a remainder of 245.
Write down 1 as next digit of the result. 
Result so far: 93357.30491
Subtract 305 from 550 to get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Step 14:
When dividing 2450 by 305, we get 8 with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 93357.304918
If we take 2440 away from 2450, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 15:
100 divided by 305 is 0 with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 93357.304918
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 16:
When dividing 1000 by 305, we get 3 with a remainder of 85.
Put 3 as the next digit of the answer. 
Result so far: 93357.30491803
If we subtract 915 from 1000, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Our division results in 93357.30491803 with a remaining 8.5e-08.
