49320123 ÷ 309 
Let's see how many times 309 fits into 49320123.

Going ahead to step 1:
4 divided by 309 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 309

Let's proceed to step 2:
309 can be fit into 49 0 times, resulting in a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 49 leaves us with 49.
Take the next digit (3) from the dividend and append it to 49, then repeat: 493 / 309

Going ahead to step 3:
309 goes into 493 1 times with a remainder of 184.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 309 from 493 leaves us with 184.
Include the next digit (2) from the dividend after 184, then repeat: 1842 / 309

Let's proceed to step 4:
The number 309 fits into 1842 5 times, leaving a remainder of 297.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 1545 away from 1842, we end up with 297.
Fetch the next digit (0) from the dividend, attach it to 297 and continue: 2970 / 309

Going ahead to step 5:
If we divide 2970 by 309, we get 9 and a remainder of 189.
The next digit of our result is 9. 
Result so far: 159.0
Subtracting 2781 from 2970 leaves us with 189.
Append the next digit (1) from the dividend to 189 and continue with: 1891 / 309

Advancing to step 6:
1891 divided by 309 is 6 with a remainder of 37.
Write down 6 as next digit of the result. 
Result so far: 1596.0
Subtract 1854 from 1891 to get 37.
Grab the next digit (2) from the dividend, add it to 37, then carry on: 372 / 309

On to step 7:
The number 309 fits into 372 1 times, leaving a remainder of 63.
The number 1 becomes the next digit in our result. 
Result so far: 15961.0
Subtract 309 from 372 to get 63.
Grab the next digit (3) from the dividend, add it to 63, then carry on: 633 / 309

Advancing to step 8:
633 divided by 309 is 2 with a remainder of 15.
The next digit of our result is 2. 
Result so far: 159612.0
Subtract 618 from 633 to get 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 9:
150 divided by 309 is 0 with a remainder of 150.
The next digit of our result is 0. 
Result so far: 159612.0
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 10:
When dividing 1500 by 309, we get 4 with a remainder of 264.
Write down 4 as next digit of the result. 
Result so far: 159612.04
The remainder is 264 after subtracting 1236 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Going ahead to step 11:
When dividing 2640 by 309, we get 8 with a remainder of 168.
The number 8 becomes the next digit in our result. 
Result so far: 159612.048
Subtracting 2472 from 2640 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 12:
309 can be fit into 1680 5 times, resulting in a remainder of 135.
The next digit of our result is 5. 
Result so far: 159612.0485
Deduct 1545 from 1680 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 13:
1350 divided by 309 is 4 with a remainder of 114.
The next digit of our result is 4. 
Result so far: 159612.04854
Subtracting 1236 from 1350 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Moving on to step 14:
When dividing 1140 by 309, we get 3 with a remainder of 213.
Put 3 as the next digit of the answer. 
Result so far: 159612.048543
Subtract 927 from 1140 to get 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Step 15:
The number 309 fits into 2130 6 times, leaving a remainder of 276.
Put 6 as the next digit of the answer. 
Result so far: 159612.0485436
The remainder is 276 after subtracting 1854 from 2130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Going ahead to step 16:
If we divide 2760 by 309, we get 8 and a remainder of 288.
The number 8 becomes the next digit in our result. 
Result so far: 159612.04854368
Deduct 2472 from 2760 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The quotient of the division is 159612.04854368, and the remainder is 2.88e-07.
