Let's divide 77205673 by 517
Let's see how many times 517 fits into 77205673.

Going ahead to step 1:
7 divided by 517 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 517

Moving on to step 2:
When dividing 77 by 517, we get 0 with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Grab the next digit (2) from the dividend, add it to 77, then carry on: 772 / 517

Step 3:
772 divided by 517 is 1 with a remainder of 255.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 517 from 772 and we're left with 255.
Include the next digit (0) from the dividend after 255, then repeat: 2550 / 517

Step 4:
When dividing 2550 by 517, we get 4 with a remainder of 482.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtract 2068 from 2550 to get 482.
Append the next digit (5) from the dividend to 482 and continue with: 4825 / 517

On to step 5:
517 goes into 4825 9 times with a remainder of 172.
Write down 9 as next digit of the result. 
Result so far: 149.0
The remainder is 172 after subtracting 4653 from 4825.
Include the next digit (6) from the dividend after 172, then repeat: 1726 / 517

Step 6:
If we divide 1726 by 517, we get 3 and a remainder of 175.
The next digit of our result is 3. 
Result so far: 1493.0
Deduct 1551 from 1726 and we're left with 175.
Take the next digit (7) from the dividend and append it to 175, then repeat: 1757 / 517

Moving on to step 7:
The number 517 fits into 1757 3 times, leaving a remainder of 206.
Write down 3 as next digit of the result. 
Result so far: 14933.0
Subtracting 1551 from 1757 leaves us with 206.
Grab the next digit (3) from the dividend, add it to 206, then carry on: 2063 / 517

Going ahead to step 8:
517 goes into 2063 3 times with a remainder of 512.
Record the quotient 3 as the next digit in the result. 
Result so far: 149333.0
Subtracting 1551 from 2063 leaves us with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Moving on to step 9:
The number 517 fits into 5120 9 times, leaving a remainder of 467.
Put 9 as the next digit of the answer. 
Result so far: 149333.9
Deduct 4653 from 5120 and we're left with 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Going ahead to step 10:
If we divide 4670 by 517, we get 9 and a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 149333.99
The remainder is 17 after subtracting 4653 from 4670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final result is 149333.99 with a remainder of 0.017.
