Let's divide 80863993 by 314
We're looking to find how many times 314 goes into 80863993.

Moving on to step 1:
314 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 314

On to step 2:
When dividing 80 by 314, we get 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Append the next digit (8) from the dividend to 80 and continue with: 808 / 314

Moving on to step 3:
314 goes into 808 2 times with a remainder of 180.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 628 from 808 leaves us with 180.
Fetch the next digit (6) from the dividend, attach it to 180 and continue: 1806 / 314

On to step 4:
When dividing 1806 by 314, we get 5 with a remainder of 236.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtracting 1570 from 1806 leaves us with 236.
Append the next digit (3) from the dividend to 236 and continue with: 2363 / 314

Step 5:
If we divide 2363 by 314, we get 7 and a remainder of 165.
The next digit of our result is 7. 
Result so far: 257.0
The remainder is 165 after subtracting 2198 from 2363.
Grab the next digit (9) from the dividend, add it to 165, then carry on: 1659 / 314

Moving on to step 6:
When dividing 1659 by 314, we get 5 with a remainder of 89.
The number 5 becomes the next digit in our result. 
Result so far: 2575.0
If we subtract 1570 from 1659, we get 89.
Bring next digit (9) of the dividend behind the 89 and repeat the process: 899 / 314

Step 7:
The number 314 fits into 899 2 times, leaving a remainder of 271.
Use 2 as the next digit of our solution. 
Result so far: 25752.0
Subtracting 628 from 899 leaves us with 271.
Bring next digit (3) of the dividend behind the 271 and repeat the process: 2713 / 314

Going ahead to step 8:
The number 314 fits into 2713 8 times, leaving a remainder of 201.
Use 8 as the next digit of our solution. 
Result so far: 257528.0
Subtracting 2512 from 2713 leaves us with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Step 9:
314 can be fit into 2010 6 times, resulting in a remainder of 126.
Put 6 as the next digit of the answer. 
Result so far: 257528.6
The remainder is 126 after subtracting 1884 from 2010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

On to step 10:
1260 divided by 314 is 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 257528.64
If we subtract 1256 from 1260, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
The number 314 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 257528.64
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
The number 314 fits into 400 1 times, leaving a remainder of 86.
Use 1 as the next digit of our solution. 
Result so far: 257528.6401
Deduct 314 from 400 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 13:
If we divide 860 by 314, we get 2 and a remainder of 232.
Write down 2 as next digit of the result. 
Result so far: 257528.64012
Subtract 628 from 860 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Let's proceed to step 14:
314 goes into 2320 7 times with a remainder of 122.
Use 7 as the next digit of our solution. 
Result so far: 257528.640127
The remainder is 122 after subtracting 2198 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 15:
314 goes into 1220 3 times with a remainder of 278.
Use 3 as the next digit of our solution. 
Result so far: 257528.6401273
Subtract 942 from 1220 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Advancing to step 16:
If we divide 2780 by 314, we get 8 and a remainder of 268.
The number 8 becomes the next digit in our result. 
Result so far: 257528.64012738
Deduct 2512 from 2780 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

The final result is 257528.64012738 with a remainder of 2.68e-07.
