Let's divide 66280605 by 829
Our goal is to divide 66280605 by 829.

Going ahead to step 1:
829 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 829

Going ahead to step 2:
829 goes into 66 0 times with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Append the next digit (2) from the dividend to 66 and continue with: 662 / 829

Let's proceed to step 3:
829 can be fit into 662 0 times, resulting in a remainder of 662.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 662, we end up with 662.
Take the next digit (8) from the dividend and append it to 662, then repeat: 6628 / 829

Going ahead to step 4:
If we divide 6628 by 829, we get 7 and a remainder of 825.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 5803 away from 6628, we end up with 825.
Append the next digit (0) from the dividend to 825 and continue with: 8250 / 829

Step 5:
The number 829 fits into 8250 9 times, leaving a remainder of 789.
Use 9 as the next digit of our solution. 
Result so far: 79.0
The remainder is 789 after subtracting 7461 from 8250.
Take the next digit (6) from the dividend and append it to 789, then repeat: 7896 / 829

Moving on to step 6:
829 goes into 7896 9 times with a remainder of 435.
Write down 9 as next digit of the result. 
Result so far: 799.0
If we subtract 7461 from 7896, we get 435.
Grab the next digit (0) from the dividend, add it to 435, then carry on: 4350 / 829

Going ahead to step 7:
The number 829 fits into 4350 5 times, leaving a remainder of 205.
Use 5 as the next digit of our solution. 
Result so far: 7995.0
Deduct 4145 from 4350 and we're left with 205.
Append the next digit (5) from the dividend to 205 and continue with: 2055 / 829

Going ahead to step 8:
If we divide 2055 by 829, we get 2 and a remainder of 397.
The number 2 becomes the next digit in our result. 
Result so far: 79952.0
The remainder is 397 after subtracting 1658 from 2055.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Let's proceed to step 9:
829 goes into 3970 4 times with a remainder of 654.
Record the quotient 4 as the next digit in the result. 
Result so far: 79952.4
Deduct 3316 from 3970 and we're left with 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Moving on to step 10:
829 goes into 6540 7 times with a remainder of 737.
Write down 7 as next digit of the result. 
Result so far: 79952.47
Deduct 5803 from 6540 and we're left with 737.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7370, and continue the process.

On to step 11:
When dividing 7370 by 829, we get 8 with a remainder of 738.
Record the quotient 8 as the next digit in the result. 
Result so far: 79952.478
The remainder is 738 after subtracting 6632 from 7370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7380, and continue the process.

Going ahead to step 12:
The number 829 fits into 7380 8 times, leaving a remainder of 748.
The number 8 becomes the next digit in our result. 
Result so far: 79952.4788
Deduct 6632 from 7380 and we're left with 748.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7480, and continue the process.

The final outcome is 79952.4788, with a leftover of 0.00748.
