We're dividing 77427031 by 317 
We want to figure out the number of times 77427031 can be divided by 317.

Step 1:
If we divide 7 by 317, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 317

Let's proceed to step 2:
When dividing 77 by 317, we get 0 with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Append the next digit (4) from the dividend to 77 and continue with: 774 / 317

On to step 3:
If we divide 774 by 317, we get 2 and a remainder of 140.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 634 from 774, we get 140.
Grab the next digit (2) from the dividend, add it to 140, then carry on: 1402 / 317

Step 4:
317 can be fit into 1402 4 times, resulting in a remainder of 134.
The next digit of our result is 4. 
Result so far: 24.0
Subtract 1268 from 1402 to get 134.
Bring next digit (7) of the dividend behind the 134 and repeat the process: 1347 / 317

Step 5:
The number 317 fits into 1347 4 times, leaving a remainder of 79.
Use 4 as the next digit of our solution. 
Result so far: 244.0
Subtract 1268 from 1347 to get 79.
Grab the next digit (0) from the dividend, add it to 79, then carry on: 790 / 317

Step 6:
When dividing 790 by 317, we get 2 with a remainder of 156.
Use 2 as the next digit of our solution. 
Result so far: 2442.0
Deduct 634 from 790 and we're left with 156.
Grab the next digit (3) from the dividend, add it to 156, then carry on: 1563 / 317

Step 7:
When dividing 1563 by 317, we get 4 with a remainder of 295.
The next digit of our result is 4. 
Result so far: 24424.0
The remainder is 295 after subtracting 1268 from 1563.
Include the next digit (1) from the dividend after 295, then repeat: 2951 / 317

Advancing to step 8:
If we divide 2951 by 317, we get 9 and a remainder of 98.
Write down 9 as next digit of the result. 
Result so far: 244249.0
Subtract 2853 from 2951 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 9:
980 divided by 317 is 3 with a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 244249.3
Subtract 951 from 980 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 10:
317 can be fit into 290 0 times, resulting in a remainder of 290.
Use 0 as the next digit of our solution. 
Result so far: 244249.3
Deduct 0 from 290 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Moving on to step 11:
When dividing 2900 by 317, we get 9 with a remainder of 47.
Use 9 as the next digit of our solution. 
Result so far: 244249.309
The remainder is 47 after subtracting 2853 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 12:
If we divide 470 by 317, we get 1 and a remainder of 153.
Write down 1 as next digit of the result. 
Result so far: 244249.3091
Subtract 317 from 470 to get 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

On to step 13:
The number 317 fits into 1530 4 times, leaving a remainder of 262.
Write down 4 as next digit of the result. 
Result so far: 244249.30914
The remainder is 262 after subtracting 1268 from 1530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

On to step 14:
317 can be fit into 2620 8 times, resulting in a remainder of 84.
Put 8 as the next digit of the answer. 
Result so far: 244249.309148
If we take 2536 away from 2620, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 15:
When dividing 840 by 317, we get 2 with a remainder of 206.
The next digit of our result is 2. 
Result so far: 244249.3091482
If we subtract 634 from 840, we get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Step 16:
The number 317 fits into 2060 6 times, leaving a remainder of 158.
The number 6 becomes the next digit in our result. 
Result so far: 244249.30914826
If we subtract 1902 from 2060, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

The final result is 244249.30914826 with a remainder of 1.58e-07.
