We're dividing 7820658 by 309 
Let's see how many times 309 fits into 7820658.

Step 1:
The number 309 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 309

Let's proceed to step 2:
The number 309 fits into 78 0 times, leaving a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Grab the next digit (2) from the dividend, add it to 78, then carry on: 782 / 309

Let's proceed to step 3:
If we divide 782 by 309, we get 2 and a remainder of 164.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 164 after subtracting 618 from 782.
Take the next digit (0) from the dividend and append it to 164, then repeat: 1640 / 309

Moving on to step 4:
If we divide 1640 by 309, we get 5 and a remainder of 95.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
The remainder is 95 after subtracting 1545 from 1640.
Bring next digit (6) of the dividend behind the 95 and repeat the process: 956 / 309

On to step 5:
309 goes into 956 3 times with a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 253.0
If we take 927 away from 956, we end up with 29.
Fetch the next digit (5) from the dividend, attach it to 29 and continue: 295 / 309

Step 6:
The number 309 fits into 295 0 times, leaving a remainder of 295.
Use 0 as the next digit of our solution. 
Result so far: 2530.0
If we take 0 away from 295, we end up with 295.
Include the next digit (8) from the dividend after 295, then repeat: 2958 / 309

Step 7:
309 goes into 2958 9 times with a remainder of 177.
The number 9 becomes the next digit in our result. 
Result so far: 25309.0
Subtracting 2781 from 2958 leaves us with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Step 8:
If we divide 1770 by 309, we get 5 and a remainder of 225.
Write down 5 as next digit of the result. 
Result so far: 25309.5
Subtract 1545 from 1770 to get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Advancing to step 9:
If we divide 2250 by 309, we get 7 and a remainder of 87.
The number 7 becomes the next digit in our result. 
Result so far: 25309.57
Subtracting 2163 from 2250 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Let's proceed to step 10:
309 goes into 870 2 times with a remainder of 252.
The next digit of our result is 2. 
Result so far: 25309.572
If we subtract 618 from 870, we get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Advancing to step 11:
309 goes into 2520 8 times with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 25309.5728
If we subtract 2472 from 2520, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 12:
309 goes into 480 1 times with a remainder of 171.
Write down 1 as next digit of the result. 
Result so far: 25309.57281
Deduct 309 from 480 and we're left with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Going ahead to step 13:
When dividing 1710 by 309, we get 5 with a remainder of 165.
Record the quotient 5 as the next digit in the result. 
Result so far: 25309.572815
Subtracting 1545 from 1710 leaves us with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 14:
309 goes into 1650 5 times with a remainder of 105.
Write down 5 as next digit of the result. 
Result so far: 25309.5728155
If we take 1545 away from 1650, we end up with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The quotient of the division is 25309.5728155, and the remainder is 1.05e-06.
