We divide 66810642 by 831
Our goal is to divide 66810642 by 831.

On to step 1:
831 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 831

Moving on to step 2:
When dividing 66 by 831, we get 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Include the next digit (8) from the dividend after 66, then repeat: 668 / 831

Step 3:
831 can be fit into 668 0 times, resulting in a remainder of 668.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 668 after subtracting 0 from 668.
Fetch the next digit (1) from the dividend, attach it to 668 and continue: 6681 / 831

On to step 4:
If we divide 6681 by 831, we get 8 and a remainder of 33.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 6648 away from 6681, we end up with 33.
Grab the next digit (0) from the dividend, add it to 33, then carry on: 330 / 831

Advancing to step 5:
330 divided by 831 is 0 with a remainder of 330.
Write down 0 as next digit of the result. 
Result so far: 80.0
Subtracting 0 from 330 leaves us with 330.
Grab the next digit (6) from the dividend, add it to 330, then carry on: 3306 / 831

Let's proceed to step 6:
831 can be fit into 3306 3 times, resulting in a remainder of 813.
Record the quotient 3 as the next digit in the result. 
Result so far: 803.0
The remainder is 813 after subtracting 2493 from 3306.
Fetch the next digit (4) from the dividend, attach it to 813 and continue: 8134 / 831

On to step 7:
If we divide 8134 by 831, we get 9 and a remainder of 655.
The next digit of our result is 9. 
Result so far: 8039.0
Subtracting 7479 from 8134 leaves us with 655.
Append the next digit (2) from the dividend to 655 and continue with: 6552 / 831

Let's proceed to step 8:
831 goes into 6552 7 times with a remainder of 735.
Record the quotient 7 as the next digit in the result. 
Result so far: 80397.0
Subtracting 5817 from 6552 leaves us with 735.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

Going ahead to step 9:
The number 831 fits into 7350 8 times, leaving a remainder of 702.
The number 8 becomes the next digit in our result. 
Result so far: 80397.8
If we take 6648 away from 7350, we end up with 702.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

Advancing to step 10:
831 can be fit into 7020 8 times, resulting in a remainder of 372.
Record the quotient 8 as the next digit in the result. 
Result so far: 80397.88
If we take 6648 away from 7020, we end up with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

In conclusion, the division gives 80397.88 with a balance of 0.372.
