79127780 ÷ 317 
Let's see how many times 317 fits into 79127780.

Going ahead to step 1:
317 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 317

On to step 2:
When dividing 79 by 317, we get 0 with a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 79 and we're left with 79.
Grab the next digit (1) from the dividend, add it to 79, then carry on: 791 / 317

On to step 3:
317 can be fit into 791 2 times, resulting in a remainder of 157.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 634 from 791 and we're left with 157.
Grab the next digit (2) from the dividend, add it to 157, then carry on: 1572 / 317

Going ahead to step 4:
If we divide 1572 by 317, we get 4 and a remainder of 304.
The next digit of our result is 4. 
Result so far: 24.0
Subtracting 1268 from 1572 leaves us with 304.
Append the next digit (7) from the dividend to 304 and continue with: 3047 / 317

Step 5:
The number 317 fits into 3047 9 times, leaving a remainder of 194.
The number 9 becomes the next digit in our result. 
Result so far: 249.0
The remainder is 194 after subtracting 2853 from 3047.
Append the next digit (7) from the dividend to 194 and continue with: 1947 / 317

Moving on to step 6:
317 goes into 1947 6 times with a remainder of 45.
The next digit of our result is 6. 
Result so far: 2496.0
If we take 1902 away from 1947, we end up with 45.
Fetch the next digit (8) from the dividend, attach it to 45 and continue: 458 / 317

Step 7:
When dividing 458 by 317, we get 1 with a remainder of 141.
Put 1 as the next digit of the answer. 
Result so far: 24961.0
If we take 317 away from 458, we end up with 141.
Fetch the next digit (0) from the dividend, attach it to 141 and continue: 1410 / 317

Let's proceed to step 8:
317 can be fit into 1410 4 times, resulting in a remainder of 142.
The next digit of our result is 4. 
Result so far: 249614.0
Deduct 1268 from 1410 and we're left with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Going ahead to step 9:
317 can be fit into 1420 4 times, resulting in a remainder of 152.
Put 4 as the next digit of the answer. 
Result so far: 249614.4
If we subtract 1268 from 1420, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 10:
317 can be fit into 1520 4 times, resulting in a remainder of 252.
The next digit of our result is 4. 
Result so far: 249614.44
The remainder is 252 after subtracting 1268 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

The final outcome is 249614.44, with a leftover of 0.252.
