Let's divide 386640 by 68
We're looking to find how many times 68 goes into 386640.

Step 1:
If we divide 3 by 68, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 68

Step 2:
If we divide 38 by 68, we get 0 and a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Include the next digit (6) from the dividend after 38, then repeat: 386 / 68

Going ahead to step 3:
If we divide 386 by 68, we get 5 and a remainder of 46.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 340 from 386 leaves us with 46.
Include the next digit (6) from the dividend after 46, then repeat: 466 / 68

Going ahead to step 4:
68 goes into 466 6 times with a remainder of 58.
Put 6 as the next digit of the answer. 
Result so far: 56.0
Subtract 408 from 466 to get 58.
Append the next digit (4) from the dividend to 58 and continue with: 584 / 68

Step 5:
68 can be fit into 584 8 times, resulting in a remainder of 40.
The next digit of our result is 8. 
Result so far: 568.0
The remainder is 40 after subtracting 544 from 584.
Append the next digit (0) from the dividend to 40 and continue with: 400 / 68

Going ahead to step 6:
If we divide 400 by 68, we get 5 and a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 5685.0
If we take 340 away from 400, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 7:
68 can be fit into 600 8 times, resulting in a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 5685.8
If we take 544 away from 600, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 8:
68 goes into 560 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 5685.88
Subtracting 544 from 560 leaves us 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.

In conclusion, the division gives 5685.88 with a balance of 0.016.
