We look at the division of 662610 by 86 
Let's see how many times 86 fits into 662610.

Step 1:
If we divide 6 by 86, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 86

Moving on 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.
Include the next digit (2) from the dividend after 66, then repeat: 662 / 86

Advancing to step 3:
If we divide 662 by 86, we get 7 and a remainder of 60.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 602 from 662, we get 60.
Include the next digit (6) from the dividend after 60, then repeat: 606 / 86

Advancing to step 4:
The number 86 fits into 606 7 times, leaving a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 77.0
Deduct 602 from 606 and we're left with 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 86

On to step 5:
86 can be fit into 41 0 times, resulting in a remainder of 41.
The number 0 becomes the next digit in our result. 
Result so far: 770.0
Subtract 0 from 41 to get 41.
Fetch the next digit (0) from the dividend, attach it to 41 and continue: 410 / 86

Let's proceed to step 6:
If we divide 410 by 86, we get 4 and a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 7704.0
Subtracting 344 from 410 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.

Let's proceed to step 7:
When dividing 660 by 86, we get 7 with a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 7704.7
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.

Moving on to step 8:
The number 86 fits into 580 6 times, leaving a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 7704.76
Subtract 516 from 580 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 9:
86 can be fit into 640 7 times, resulting in a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 7704.767
If we subtract 602 from 640, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 10:
The number 86 fits into 380 4 times, leaving a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 7704.7674
Subtract 344 from 380 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 11:
360 divided by 86 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 7704.76744
Deduct 344 from 360 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 7704.76744 and a remainder of 1.6e-05.
