We're dividing 76290431 by 309 
Let's see how many times 309 fits into 76290431.

Moving on to step 1:
The number 309 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 309

Let's proceed to step 2:
The number 309 fits into 76 0 times, leaving a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Include the next digit (2) from the dividend after 76, then repeat: 762 / 309

Let's proceed to step 3:
762 divided by 309 is 2 with a remainder of 144.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 618 from 762 leaves us with 144.
Bring next digit (9) of the dividend behind the 144 and repeat the process: 1449 / 309

Moving on to step 4:
When dividing 1449 by 309, we get 4 with a remainder of 213.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
If we take 1236 away from 1449, we end up with 213.
Include the next digit (0) from the dividend after 213, then repeat: 2130 / 309

Step 5:
309 goes into 2130 6 times with a remainder of 276.
The next digit of our result is 6. 
Result so far: 246.0
The remainder is 276 after subtracting 1854 from 2130.
Take the next digit (4) from the dividend and append it to 276, then repeat: 2764 / 309

Moving on to step 6:
When dividing 2764 by 309, we get 8 with a remainder of 292.
Put 8 as the next digit of the answer. 
Result so far: 2468.0
If we subtract 2472 from 2764, we get 292.
Take the next digit (3) from the dividend and append it to 292, then repeat: 2923 / 309

Going ahead to step 7:
When dividing 2923 by 309, we get 9 with a remainder of 142.
Use 9 as the next digit of our solution. 
Result so far: 24689.0
Subtracting 2781 from 2923 leaves us with 142.
Include the next digit (1) from the dividend after 142, then repeat: 1421 / 309

Advancing to step 8:
The number 309 fits into 1421 4 times, leaving a remainder of 185.
Use 4 as the next digit of our solution. 
Result so far: 246894.0
Subtracting 1236 from 1421 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Let's proceed to step 9:
309 can be fit into 1850 5 times, resulting in a remainder of 305.
The number 5 becomes the next digit in our result. 
Result so far: 246894.5
Deduct 1545 from 1850 and we're left with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Let's proceed to step 10:
When dividing 3050 by 309, we get 9 with a remainder of 269.
Write down 9 as next digit of the result. 
Result so far: 246894.59
If we take 2781 away from 3050, we end up with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Step 11:
309 goes into 2690 8 times with a remainder of 218.
The next digit of our result is 8. 
Result so far: 246894.598
The remainder is 218 after subtracting 2472 from 2690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

On to step 12:
If we divide 2180 by 309, we get 7 and a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 246894.5987
If we subtract 2163 from 2180, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 13:
When dividing 170 by 309, we get 0 with a remainder of 170.
The next digit of our result is 0. 
Result so far: 246894.5987
If we take 0 away from 170, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 14:
When dividing 1700 by 309, we get 5 with a remainder of 155.
Put 5 as the next digit of the answer. 
Result so far: 246894.598705
Subtracting 1545 from 1700 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Let's proceed to step 15:
The number 309 fits into 1550 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 246894.5987055
Subtracting 1545 from 1550 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 246894.5987055 with a remainder of 5e-08.
