Append the next digit (5) from the dividend to 149 and continue with: 1495 / 309

Advancing to step 4:
The number 309 fits into 1495 4 times, leaving a remainder of 259.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 1236 from 1495 leaves us with 259.
Bring next digit (3) of the dividend behind the 259 and repeat the process: 2593 / 309

Advancing to step 5:
309 can be fit into 2593 8 times, resulting in a remainder of 121.
The next digit of our result is 8. 
Result so far: 148.0
Subtracting 2472 from 2593 leaves us with 121.
Take the next digit (7) from the dividend and append it to 121, then repeat: 1217 / 309

Step 6:
The number 309 fits into 1217 3 times, leaving a remainder of 290.
Put 3 as the next digit of the answer. 
Result so far: 1483.0
If we take 927 away from 1217, we end up with 290.
Bring next digit (6) of the dividend behind the 290 and repeat the process: 2906 / 309

Step 7:
If we divide 2906 by 309, we get 9 and a remainder of 125.
Record the quotient 9 as the next digit in the result. 
Result so far: 14839.0
Subtract 2781 from 2906 to get 125.
Bring next digit (0) of the dividend behind the 125 and repeat the process: 1250 / 309

Let's proceed to step 8:
The number 309 fits into 1250 4 times, leaving a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 148394.0
Subtract 1236 from 1250 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
140 divided by 309 is 0 with a remainder of 140.
Put 0 as the next digit of the answer. 
Result so far: 148394.0
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 10:
If we divide 1400 by 309, we get 4 and a remainder of 164.
The next digit of our result is 4. 
Result so far: 148394.04
If we subtract 1236 from 1400, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 11:
309 can be fit into 1640 5 times, resulting in a remainder of 95.
Use 5 as the next digit of our solution. 
Result so far: 148394.045
The remainder is 95 after subtracting 1545 from 1640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 12:
The number 309 fits into 950 3 times, leaving a remainder of 23.
The next digit of our result is 3. 
Result so far: 148394.0453
Deduct 927 from 950 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 13:
The number 309 fits into 230 0 times, leaving a remainder of 230.
Put 0 as the next digit of the answer. 
Result so far: 148394.0453
If we take 0 away from 230, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 14:
When dividing 2300 by 309, we get 7 with a remainder of 137.
Write down 7 as next digit of the result. 
Result so far: 148394.045307
The remainder is 137 after subtracting 2163 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Moving on to step 15:
If we divide 1370 by 309, we get 4 and a remainder of 134.
Write down 4 as next digit of the result. 
Result so far: 148394.0453074
Subtracting 1236 from 1370 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Moving on to step 16:
If we divide 1340 by 309, we get 4 and a remainder of 104.
The number 4 becomes the next digit in our result. 
Result so far: 148394.04530744
Deduct 1236 from 1340 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The final result is 148394.04530744 with a remainder of 1.04e-07.
