66866602 ÷ 727 
We want to divide 66866602 by 727.

Moving on to step 1:
727 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 727

Advancing to step 2:
When dividing 66 by 727, we get 0 with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Fetch the next digit (8) from the dividend, attach it to 66 and continue: 668 / 727

Advancing to step 3:
668 divided by 727 is 0 with 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 (6) from the dividend to 668 and continue with: 6686 / 727

Going ahead to step 4:
When dividing 6686 by 727, we get 9 with a remainder of 143.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 6543 from 6686 leaves us with 143.
Fetch the next digit (6) from the dividend, attach it to 143 and continue: 1436 / 727

Moving on to step 5:
727 goes into 1436 1 times with a remainder of 709.
Use 1 as the next digit of our solution. 
Result so far: 91.0
If we take 727 away from 1436, we end up with 709.
Bring next digit (6) of the dividend behind the 709 and repeat the process: 7096 / 727

Step 6:
7096 divided by 727 is 9 with a remainder of 553.
Write down 9 as next digit of the result. 
Result so far: 919.0
The remainder is 553 after subtracting 6543 from 7096.
Append the next digit (0) from the dividend to 553 and continue with: 5530 / 727

On to step 7:
727 goes into 5530 7 times with a remainder of 441.
Use 7 as the next digit of our solution. 
Result so far: 9197.0
Subtracting 5089 from 5530 leaves us with 441.
Append the next digit (2) from the dividend to 441 and continue with: 4412 / 727

Moving on to step 8:
727 goes into 4412 6 times with a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 91976.0
If we take 4362 away from 4412, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
727 can be fit into 500 0 times, resulting in a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 91976.0
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 10:
If we divide 5000 by 727, we get 6 and a remainder of 638.
The number 6 becomes the next digit in our result. 
Result so far: 91976.06
Subtract 4362 from 5000 to get 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Step 11:
727 can be fit into 6380 8 times, resulting in a remainder of 564.
The number 8 becomes the next digit in our result. 
Result so far: 91976.068
Subtract 5816 from 6380 to get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Going ahead to step 12:
If we divide 5640 by 727, we get 7 and a remainder of 551.
The next digit of our result is 7. 
Result so far: 91976.0687
If we take 5089 away from 5640, we end up with 551.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5510, and continue the process.

On to step 13:
If we divide 5510 by 727, we get 7 and a remainder of 421.
Write down 7 as next digit of the result. 
Result so far: 91976.06877
Subtracting 5089 from 5510 leaves us with 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

The quotient of the division is 91976.06877, and the remainder is 0.000421.
