Let's divide 66850439 by 317
Our goal is to divide 66850439 by 317.

Going ahead to step 1:
6 divided by 317 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 317

Step 2:
When dividing 66 by 317, we get 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Fetch the next digit (8) from the dividend, attach it to 66 and continue: 668 / 317

Let's proceed to step 3:
When dividing 668 by 317, we get 2 with a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 634 from 668 and we're left with 34.
Bring next digit (5) of the dividend behind the 34 and repeat the process: 345 / 317

Let's proceed to step 4:
When dividing 345 by 317, we get 1 with a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
The remainder is 28 after subtracting 317 from 345.
Take the next digit (0) from the dividend and append it to 28, then repeat: 280 / 317

Step 5:
When dividing 280 by 317, we get 0 with a remainder of 280.
Use 0 as the next digit of our solution. 
Result so far: 210.0
If we subtract 0 from 280, we get 280.
Bring next digit (4) of the dividend behind the 280 and repeat the process: 2804 / 317

Going ahead to step 6:
When dividing 2804 by 317, we get 8 with a remainder of 268.
Write down 8 as next digit of the result. 
Result so far: 2108.0
Subtracting 2536 from 2804 leaves us with 268.
Take the next digit (3) from the dividend and append it to 268, then repeat: 2683 / 317

Moving on to step 7:
When dividing 2683 by 317, we get 8 with a remainder of 147.
The next digit of our result is 8. 
Result so far: 21088.0
If we subtract 2536 from 2683, we get 147.
Bring next digit (9) of the dividend behind the 147 and repeat the process: 1479 / 317

Going ahead to step 8:
If we divide 1479 by 317, we get 4 and a remainder of 211.
Put 4 as the next digit of the answer. 
Result so far: 210884.0
Deduct 1268 from 1479 and we're left with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Going ahead to step 9:
The number 317 fits into 2110 6 times, leaving a remainder of 208.
Use 6 as the next digit of our solution. 
Result so far: 210884.6
If we subtract 1902 from 2110, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 10:
The number 317 fits into 2080 6 times, leaving a remainder of 178.
Record the quotient 6 as the next digit in the result. 
Result so far: 210884.66
If we subtract 1902 from 2080, we get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

In conclusion, the division gives 210884.66 with a balance of 0.178.
