517873 ÷ 68 
We're looking to find how many times 68 goes into 517873.

Going ahead to step 1:
68 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
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:
If we divide 51 by 68, we get 0 and a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Fetch the next digit (7) from the dividend, attach it to 51 and continue: 517 / 68

Going ahead to step 3:
68 goes into 517 7 times with a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 476 from 517 and we're left with 41.
Grab the next digit (8) from the dividend, add it to 41, then carry on: 418 / 68

Moving on to step 4:
When dividing 418 by 68, we get 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 76.0
Subtract 408 from 418 to get 10.
Fetch the next digit (7) from the dividend, attach it to 10 and continue: 107 / 68

On to step 5:
68 goes into 107 1 times with a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 761.0
Subtract 68 from 107 to get 39.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 68

Going ahead to step 6:
When dividing 393 by 68, we get 5 with a remainder of 53.
Write down 5 as next digit of the result. 
Result so far: 7615.0
The remainder is 53 after subtracting 340 from 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 7:
530 divided by 68 is 7 with a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 7615.7
The remainder is 54 after subtracting 476 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 8:
68 goes into 540 7 times with a remainder of 64.
Use 7 as the next digit of our solution. 
Result so far: 7615.77
Deduct 476 from 540 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 7615.77 and a remainder of 0.064.
