Let's divide 66881207 by 823
We want to divide 66881207 by 823.

On to step 1:
If we divide 6 by 823, we get 0 and 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.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 823

Step 2:
When dividing 66 by 823, we get 0 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.
Fetch the next digit (8) from the dividend, attach it to 66 and continue: 668 / 823

Going ahead to step 3:
The number 823 fits into 668 0 times, leaving a remainder of 668.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 668, we get 668.
Append the next digit (8) from the dividend to 668 and continue with: 6688 / 823

Let's proceed to step 4:
6688 divided by 823 is 8 with a remainder of 104.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 6584 from 6688 to get 104.
Grab the next digit (1) from the dividend, add it to 104, then carry on: 1041 / 823

Going ahead to step 5:
823 goes into 1041 1 times with a remainder of 218.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
The remainder is 218 after subtracting 823 from 1041.
Append the next digit (2) from the dividend to 218 and continue with: 2182 / 823

Step 6:
823 can be fit into 2182 2 times, resulting in a remainder of 536.
Put 2 as the next digit of the answer. 
Result so far: 812.0
The remainder is 536 after subtracting 1646 from 2182.
Grab the next digit (0) from the dividend, add it to 536, then carry on: 5360 / 823

Going ahead to step 7:
823 goes into 5360 6 times with a remainder of 422.
Use 6 as the next digit of our solution. 
Result so far: 8126.0
Subtract 4938 from 5360 to get 422.
Bring next digit (7) of the dividend behind the 422 and repeat the process: 4227 / 823

On to step 8:
When dividing 4227 by 823, we get 5 with a remainder of 112.
Write down 5 as next digit of the result. 
Result so far: 81265.0
Subtract 4115 from 4227 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 9:
If we divide 1120 by 823, we get 1 and a remainder of 297.
Put 1 as the next digit of the answer. 
Result so far: 81265.1
If we subtract 823 from 1120, we get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Step 10:
If we divide 2970 by 823, we get 3 and a remainder of 501.
Write down 3 as next digit of the result. 
Result so far: 81265.13
If we subtract 2469 from 2970, we get 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Advancing to step 11:
If we divide 5010 by 823, we get 6 and a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 81265.136
If we take 4938 away from 5010, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 12:
720 divided by 823 is 0 with a remainder of 720.
Record the quotient 0 as the next digit in the result. 
Result so far: 81265.136
The remainder is 720 after subtracting 0 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Let's proceed to step 13:
823 can be fit into 7200 8 times, resulting in a remainder of 616.
The number 8 becomes the next digit in our result. 
Result so far: 81265.13608
Deduct 6584 from 7200 and we're left with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Let's proceed to step 14:
823 goes into 6160 7 times with a remainder of 399.
Write down 7 as next digit of the result. 
Result so far: 81265.136087
Subtracting 5761 from 6160 leaves us with 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Let's proceed to step 15:
823 can be fit into 3990 4 times, resulting in a remainder of 698.
The next digit of our result is 4. 
Result so far: 81265.1360874
Subtract 3292 from 3990 to get 698.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6980, and continue the process.

Going ahead to step 16:
823 goes into 6980 8 times with a remainder of 396.
Use 8 as the next digit of our solution. 
Result so far: 81265.13608748
Subtract 6584 from 6980 to get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

After the division, we end up with 81265.13608748 and a remainder of 3.96e-07.
