We're dividing 660004 by 86 
We want to figure out the number of times 660004 can be divided by 86.

Let's proceed to step 1:
6 divided by 86 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 86

Advancing to step 2:
66 divided by 86 is 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Take the next digit (0) from the dividend and append it to 66, then repeat: 660 / 86

Advancing to step 3:
86 goes into 660 7 times with a remainder of 58.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 602 from 660 to get 58.
Append the next digit (0) from the dividend to 58 and continue with: 580 / 86

Advancing to step 4:
If we divide 580 by 86, we get 6 and a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 76.0
The remainder is 64 after subtracting 516 from 580.
Include the next digit (0) from the dividend after 64, then repeat: 640 / 86

Let's proceed to step 5:
If we divide 640 by 86, we get 7 and a remainder of 38.
The next digit of our result is 7. 
Result so far: 767.0
Subtract 602 from 640 to get 38.
Take the next digit (4) from the dividend and append it to 38, then repeat: 384 / 86

Going ahead to step 6:
384 divided by 86 is 4 with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 7674.0
If we take 344 away from 384, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 7:
If we divide 400 by 86, we get 4 and a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 7674.4
If we subtract 344 from 400, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 8:
When dividing 560 by 86, we get 6 with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 7674.46
Subtract 516 from 560 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 9:
86 can be fit into 440 5 times, resulting in a remainder of 10.
The next digit of our result is 5. 
Result so far: 7674.465
If we subtract 430 from 440, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
86 goes into 100 1 times with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 7674.4651
Deduct 86 from 100 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
If we divide 140 by 86, we get 1 and a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 7674.46511
The remainder is 54 after subtracting 86 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 7674.46511 with a remainder of 5.4e-05.
