We look at the division of 660018 by 86 
Let's see how many times 86 fits into 660018.

On to step 1:
When dividing 6 by 86, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 86

Step 2:
When dividing 66 by 86, we get 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Fetch the next digit (0) from the dividend, attach it to 66 and continue: 660 / 86

Let's proceed to step 3:
86 can be fit into 660 7 times, resulting in a remainder of 58.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 602 from 660, we get 58.
Grab the next digit (0) from the dividend, add it to 58, then carry on: 580 / 86

On to step 4:
580 divided by 86 is 6 with a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
The remainder is 64 after subtracting 516 from 580.
Include the next digit (1) from the dividend after 64, then repeat: 641 / 86

Let's proceed to step 5:
86 goes into 641 7 times with a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 767.0
Subtracting 602 from 641 leaves us with 39.
Grab the next digit (8) from the dividend, add it to 39, then carry on: 398 / 86

Moving on to step 6:
The number 86 fits into 398 4 times, leaving a remainder of 54.
The number 4 becomes the next digit in our result. 
Result so far: 7674.0
If we subtract 344 from 398, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 7:
If we divide 540 by 86, we get 6 and a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 7674.6
If we take 516 away from 540, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 8:
240 divided by 86 is 2 with a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 7674.62
Subtracting 172 from 240 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 9:
86 can be fit into 680 7 times, resulting in a remainder of 78.
Write down 7 as next digit of the result. 
Result so far: 7674.627
Subtract 602 from 680 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 10:
When dividing 780 by 86, we get 9 with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 7674.6279
Subtract 774 from 780 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 11:
The number 86 fits into 60 0 times, leaving a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 7674.6279
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 12:
86 can be fit into 600 6 times, resulting in a remainder of 84.
The next digit of our result is 6. 
Result so far: 7674.627906
Subtracting 516 from 600 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 13:
86 goes into 840 9 times with a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 7674.6279069
Subtracting 774 from 840 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 14:
660 divided by 86 is 7 with a remainder of 58.
The next digit of our result is 7. 
Result so far: 7674.62790697
The remainder is 58 after subtracting 602 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The final outcome is 7674.62790697, with a leftover of 5.8e-08.
