80564942 ÷ 317 
Let's see how many times 317 fits into 80564942.

Moving on to step 1:
317 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 317

Step 2:
The number 317 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Grab the next digit (5) from the dividend, add it to 80, then carry on: 805 / 317

Let's proceed to step 3:
317 goes into 805 2 times with a remainder of 171.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 634 from 805 to get 171.
Take the next digit (6) from the dividend and append it to 171, then repeat: 1716 / 317

Going ahead to step 4:
317 can be fit into 1716 5 times, resulting in a remainder of 131.
Put 5 as the next digit of the answer. 
Result so far: 25.0
If we subtract 1585 from 1716, we get 131.
Append the next digit (4) from the dividend to 131 and continue with: 1314 / 317

Step 5:
The number 317 fits into 1314 4 times, leaving a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 254.0
Subtract 1268 from 1314 to get 46.
Take the next digit (9) from the dividend and append it to 46, then repeat: 469 / 317

Moving on to step 6:
If we divide 469 by 317, we get 1 and a remainder of 152.
Use 1 as the next digit of our solution. 
Result so far: 2541.0
Subtract 317 from 469 to get 152.
Take the next digit (4) from the dividend and append it to 152, then repeat: 1524 / 317

Moving on to step 7:
If we divide 1524 by 317, we get 4 and a remainder of 256.
Put 4 as the next digit of the answer. 
Result so far: 25414.0
If we subtract 1268 from 1524, we get 256.
Bring next digit (2) of the dividend behind the 256 and repeat the process: 2562 / 317

Step 8:
2562 divided by 317 is 8 with a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 254148.0
Subtracting 2536 from 2562 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 9:
317 can be fit into 260 0 times, resulting in a remainder of 260.
Write down 0 as next digit of the result. 
Result so far: 254148.0
The remainder is 260 after subtracting 0 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 10:
When dividing 2600 by 317, we get 8 with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 254148.08
The remainder is 64 after subtracting 2536 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 11:
317 can be fit into 640 2 times, resulting in a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 254148.082
If we subtract 634 from 640, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 12:
When dividing 60 by 317, we get 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 254148.082
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 13:
317 can be fit into 600 1 times, resulting in a remainder of 283.
Put 1 as the next digit of the answer. 
Result so far: 254148.08201
Deduct 317 from 600 and we're left with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Advancing to step 14:
If we divide 2830 by 317, we get 8 and a remainder of 294.
Record the quotient 8 as the next digit in the result. 
Result so far: 254148.082018
Subtract 2536 from 2830 to get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Moving on to step 15:
The number 317 fits into 2940 9 times, leaving a remainder of 87.
Record the quotient 9 as the next digit in the result. 
Result so far: 254148.0820189
If we subtract 2853 from 2940, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 16:
The number 317 fits into 870 2 times, leaving a remainder of 236.
The next digit of our result is 2. 
Result so far: 254148.08201892
If we subtract 634 from 870, we get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

The final outcome is 254148.08201892, with a leftover of 2.36e-07.
