Let's divide 6664355 by 831
We want to figure out the number of times 6664355 can be divided by 831.

Going ahead to step 1:
831 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 831

On to step 2:
The number 831 fits into 66 0 times, leaving a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Append the next digit (6) from the dividend to 66 and continue with: 666 / 831

Going ahead to step 3:
666 divided by 831 is 0 with a remainder of 666.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 666 to get 666.
Take the next digit (4) from the dividend and append it to 666, then repeat: 6664 / 831

Going ahead to step 4:
831 goes into 6664 8 times with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 6648 from 6664 leaves us with 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 831

Advancing to step 5:
831 goes into 163 0 times with a remainder of 163.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
The remainder is 163 after subtracting 0 from 163.
Bring next digit (5) of the dividend behind the 163 and repeat the process: 1635 / 831

Moving on to step 6:
831 can be fit into 1635 1 times, resulting in a remainder of 804.
Record the quotient 1 as the next digit in the result. 
Result so far: 801.0
The remainder is 804 after subtracting 831 from 1635.
Bring next digit (5) of the dividend behind the 804 and repeat the process: 8045 / 831

On to step 7:
831 can be fit into 8045 9 times, resulting in a remainder of 566.
Put 9 as the next digit of the answer. 
Result so far: 8019.0
The remainder is 566 after subtracting 7479 from 8045.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Advancing to step 8:
5660 divided by 831 is 6 with a remainder of 674.
The number 6 becomes the next digit in our result. 
Result so far: 8019.6
Deduct 4986 from 5660 and we're left with 674.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6740, and continue the process.

Moving on to step 9:
831 goes into 6740 8 times with a remainder of 92.
Put 8 as the next digit of the answer. 
Result so far: 8019.68
The remainder is 92 after subtracting 6648 from 6740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 10:
920 divided by 831 is 1 with a remainder of 89.
Put 1 as the next digit of the answer. 
Result so far: 8019.681
The remainder is 89 after subtracting 831 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Moving on to step 11:
When dividing 890 by 831, we get 1 with a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 8019.6811
Subtract 831 from 890 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

After the division, we end up with 8019.6811 and a remainder of 0.00059.
