Let's divide 80670303 by 517
Let's see how many times 517 fits into 80670303.

Let's proceed to step 1:
517 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 517

Moving on to step 2:
517 goes into 80 0 times with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Include the next digit (6) from the dividend after 80, then repeat: 806 / 517

Moving on to step 3:
The number 517 fits into 806 1 times, leaving a remainder of 289.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 517 from 806, we get 289.
Take the next digit (7) from the dividend and append it to 289, then repeat: 2897 / 517

Step 4:
517 can be fit into 2897 5 times, resulting in a remainder of 312.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 2585 away from 2897, we end up with 312.
Bring next digit (0) of the dividend behind the 312 and repeat the process: 3120 / 517

Moving on to step 5:
517 can be fit into 3120 6 times, resulting in a remainder of 18.
The next digit of our result is 6. 
Result so far: 156.0
If we subtract 3102 from 3120, we get 18.
Append the next digit (3) from the dividend to 18 and continue with: 183 / 517

On to step 6:
If we divide 183 by 517, we get 0 and a remainder of 183.
The number 0 becomes the next digit in our result. 
Result so far: 1560.0
If we subtract 0 from 183, we get 183.
Grab the next digit (0) from the dividend, add it to 183, then carry on: 1830 / 517

Advancing to step 7:
1830 divided by 517 is 3 with a remainder of 279.
Write down 3 as next digit of the result. 
Result so far: 15603.0
Subtracting 1551 from 1830 leaves us with 279.
Grab the next digit (3) from the dividend, add it to 279, then carry on: 2793 / 517

Advancing to step 8:
The number 517 fits into 2793 5 times, leaving a remainder of 208.
Put 5 as the next digit of the answer. 
Result so far: 156035.0
If we subtract 2585 from 2793, 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 9:
2080 divided by 517 is 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 156035.4
The remainder is 12 after subtracting 2068 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 10:
The number 517 fits into 120 0 times, leaving a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 156035.4
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 11:
517 can be fit into 1200 2 times, resulting in a remainder of 166.
The number 2 becomes the next digit in our result. 
Result so far: 156035.402
If we take 1034 away from 1200, we end up with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

On to step 12:
The number 517 fits into 1660 3 times, leaving a remainder of 109.
The next digit of our result is 3. 
Result so far: 156035.4023
If we take 1551 away from 1660, we end up with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Step 13:
When dividing 1090 by 517, we get 2 with a remainder of 56.
Put 2 as the next digit of the answer. 
Result so far: 156035.40232
If we take 1034 away from 1090, 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.

Advancing to step 14:
The number 517 fits into 560 1 times, leaving a remainder of 43.
Use 1 as the next digit of our solution. 
Result so far: 156035.402321
The remainder is 43 after subtracting 517 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 15:
430 divided by 517 is 0 with a remainder of 430.
Write down 0 as next digit of the result. 
Result so far: 156035.402321
Subtract 0 from 430 to get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Going ahead to step 16:
The number 517 fits into 4300 8 times, leaving a remainder of 164.
Put 8 as the next digit of the answer. 
Result so far: 156035.40232108
The remainder is 164 after subtracting 4136 from 4300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

The final result is 156035.40232108 with a remainder of 1.64e-07.
