Let's divide 660488 by 86
We want to figure out the number of times 660488 can be divided by 86.

On to step 1:
6 divided by 86 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 86

Let's proceed to step 2:
If we divide 66 by 86, we get 0 and a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Bring next digit (0) of the dividend behind the 66 and repeat the process: 660 / 86

Moving on to step 3:
The number 86 fits into 660 7 times, leaving a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 602 from 660 to get 58.
Fetch the next digit (4) from the dividend, attach it to 58 and continue: 584 / 86

Step 4:
If we divide 584 by 86, we get 6 and a remainder of 68.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
Subtract 516 from 584 to get 68.
Fetch the next digit (8) from the dividend, attach it to 68 and continue: 688 / 86

Going ahead to step 5:
86 can be fit into 688 8 times, resulting in a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 768.0
If we take 688 away from 688, we end up with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 86

Let's proceed to step 6:
86 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 7680.0
Subtracting 0 from 8 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
The number 86 fits into 80 0 times, leaving a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 7680.0
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 8:
If we divide 800 by 86, we get 9 and a remainder of 26.
The next digit of our result is 9. 
Result so far: 7680.09
If we subtract 774 from 800, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 9:
86 goes into 260 3 times with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 7680.093
The remainder is 2 after subtracting 258 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
The number 86 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 7680.093
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
200 divided by 86 is 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 7680.09302
Deduct 172 from 200 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 12:
The number 86 fits into 280 3 times, leaving a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 7680.093023
Subtracting 258 from 280 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 13:
220 divided by 86 is 2 with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 7680.0930232
Subtract 172 from 220 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 14:
The number 86 fits into 480 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 7680.09302325
If we subtract 430 from 480, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 7680.09302325 with a remainder of 5e-08.
