We're dividing 666485 by 71 
We want to figure out the number of times 666485 can be divided by 71.

Moving on to step 1:
6 divided by 71 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 71

Advancing to step 2:
71 goes into 66 0 times with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Grab the next digit (6) from the dividend, add it to 66, then carry on: 666 / 71

Advancing to step 3:
71 goes into 666 9 times with a remainder of 27.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 639 from 666, we get 27.
Include the next digit (4) from the dividend after 27, then repeat: 274 / 71

Advancing to step 4:
274 divided by 71 is 3 with a remainder of 61.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
If we take 213 away from 274, we end up with 61.
Append the next digit (8) from the dividend to 61 and continue with: 618 / 71

Going ahead to step 5:
618 divided by 71 is 8 with a remainder of 50.
The next digit of our result is 8. 
Result so far: 938.0
Subtracting 568 from 618 leaves us with 50.
Take the next digit (5) from the dividend and append it to 50, then repeat: 505 / 71

Moving on to step 6:
The number 71 fits into 505 7 times, leaving a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 9387.0
If we subtract 497 from 505, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
71 can be fit into 80 1 times, resulting in a remainder of 9.
The next digit of our result is 1. 
Result so far: 9387.1
If we subtract 71 from 80, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 8:
The number 71 fits into 90 1 times, leaving a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 9387.11
Subtract 71 from 90 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Our division results in 9387.11 with a remaining 0.019.
