We look at the division of 517391 by 68 
We want to divide 517391 by 68.

On to step 1:
If we divide 5 by 68, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 68

On to step 2:
51 divided by 68 is 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Bring next digit (7) of the dividend behind the 51 and repeat the process: 517 / 68

Moving on to step 3:
517 divided by 68 is 7 with a remainder of 41.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 476 from 517 to get 41.
Bring next digit (3) of the dividend behind the 41 and repeat the process: 413 / 68

Let's proceed to step 4:
The number 68 fits into 413 6 times, leaving a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
Deduct 408 from 413 and we're left with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 68

Advancing to step 5:
If we divide 59 by 68, we get 0 and a remainder of 59.
Put 0 as the next digit of the answer. 
Result so far: 760.0
If we take 0 away from 59, we end up with 59.
Append the next digit (1) from the dividend to 59 and continue with: 591 / 68

Step 6:
If we divide 591 by 68, we get 8 and a remainder of 47.
Put 8 as the next digit of the answer. 
Result so far: 7608.0
Subtracting 544 from 591 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 7:
68 goes into 470 6 times with a remainder of 62.
Use 6 as the next digit of our solution. 
Result so far: 7608.6
If we take 408 away from 470, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 8:
68 can be fit into 620 9 times, resulting in a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 7608.69
Subtracting 612 from 620 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.

Going ahead to step 9:
If we divide 80 by 68, we get 1 and a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 7608.691
The remainder is 12 after subtracting 68 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
When dividing 120 by 68, we get 1 with a remainder of 52.
The next digit of our result is 1. 
Result so far: 7608.6911
Subtract 68 from 120 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

In conclusion, the division gives 7608.6911 with a balance of 0.00052.
