66819694 ÷ 871 
Our goal is to divide 66819694 by 871.

Advancing to step 1:
If we divide 6 by 871, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 871

Advancing to step 2:
66 divided by 871 is 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Fetch the next digit (8) from the dividend, attach it to 66 and continue: 668 / 871

Going ahead to step 3:
The number 871 fits into 668 0 times, leaving a remainder of 668.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 668, we end up with 668.
Fetch the next digit (1) from the dividend, attach it to 668 and continue: 6681 / 871

On to step 4:
6681 divided by 871 is 7 with a remainder of 584.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 6097 away from 6681, we end up with 584.
Append the next digit (9) from the dividend to 584 and continue with: 5849 / 871

Moving on to step 5:
5849 divided by 871 is 6 with a remainder of 623.
Record the quotient 6 as the next digit in the result. 
Result so far: 76.0
Deduct 5226 from 5849 and we're left with 623.
Take the next digit (6) from the dividend and append it to 623, then repeat: 6236 / 871

Advancing to step 6:
871 can be fit into 6236 7 times, resulting in a remainder of 139.
Use 7 as the next digit of our solution. 
Result so far: 767.0
If we subtract 6097 from 6236, we get 139.
Grab the next digit (9) from the dividend, add it to 139, then carry on: 1399 / 871

Advancing to step 7:
When dividing 1399 by 871, we get 1 with a remainder of 528.
The number 1 becomes the next digit in our result. 
Result so far: 7671.0
If we subtract 871 from 1399, we get 528.
Fetch the next digit (4) from the dividend, attach it to 528 and continue: 5284 / 871

Going ahead to step 8:
The number 871 fits into 5284 6 times, leaving a remainder of 58.
Put 6 as the next digit of the answer. 
Result so far: 76716.0
If we subtract 5226 from 5284, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 9:
If we divide 580 by 871, we get 0 and a remainder of 580.
The number 0 becomes the next digit in our result. 
Result so far: 76716.0
Subtracting 0 from 580 leaves us with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Step 10:
871 goes into 5800 6 times with a remainder of 574.
Put 6 as the next digit of the answer. 
Result so far: 76716.06
If we take 5226 away from 5800, we end up with 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Step 11:
If we divide 5740 by 871, we get 6 and a remainder of 514.
Use 6 as the next digit of our solution. 
Result so far: 76716.066
The remainder is 514 after subtracting 5226 from 5740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

The quotient of the division is 76716.066, and the remainder is 0.0514.
