We're dividing 660940 by 86 
Let's see how many times 86 fits into 660940.

Step 1:
86 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 86

Moving on to step 2:
When dividing 66 by 86, we get 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Grab the next digit (0) from the dividend, add it to 66, then carry on: 660 / 86

Step 3:
86 goes into 660 7 times with a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 602 from 660 leaves us with 58.
Fetch the next digit (9) from the dividend, attach it to 58 and continue: 589 / 86

Going ahead to step 4:
When dividing 589 by 86, we get 6 with a remainder of 73.
Put 6 as the next digit of the answer. 
Result so far: 76.0
The remainder is 73 after subtracting 516 from 589.
Fetch the next digit (4) from the dividend, attach it to 73 and continue: 734 / 86

Advancing to step 5:
734 divided by 86 is 8 with a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 768.0
Subtract 688 from 734 to get 46.
Grab the next digit (0) from the dividend, add it to 46, then carry on: 460 / 86

Going ahead to step 6:
When dividing 460 by 86, we get 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 7685.0
Subtract 430 from 460 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 7:
300 divided by 86 is 3 with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 7685.3
Deduct 258 from 300 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 8:
420 divided by 86 is 4 with a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 7685.34
If we subtract 344 from 420, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 9:
If we divide 760 by 86, we get 8 and a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 7685.348
The remainder is 72 after subtracting 688 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 10:
If we divide 720 by 86, we get 8 and a remainder of 32.
The next digit of our result is 8. 
Result so far: 7685.3488
If we subtract 688 from 720, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 7685.3488 with a remaining 0.00032.
