We're dividing 80805756 by 312 
Let's see how many times 312 fits into 80805756.

Step 1:
The number 312 fits into 8 0 times, leaving 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.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 312

Going ahead to step 2:
When dividing 80 by 312, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Include the next digit (8) from the dividend after 80, then repeat: 808 / 312

On to step 3:
The number 312 fits into 808 2 times, leaving a remainder of 184.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 624 away from 808, we end up with 184.
Fetch the next digit (0) from the dividend, attach it to 184 and continue: 1840 / 312

Moving on to step 4:
The number 312 fits into 1840 5 times, leaving a remainder of 280.
Use 5 as the next digit of our solution. 
Result so far: 25.0
The remainder is 280 after subtracting 1560 from 1840.
Take the next digit (5) from the dividend and append it to 280, then repeat: 2805 / 312

Going ahead to step 5:
2805 divided by 312 is 8 with a remainder of 309.
Write down 8 as next digit of the result. 
Result so far: 258.0
If we take 2496 away from 2805, we end up with 309.
Take the next digit (7) from the dividend and append it to 309, then repeat: 3097 / 312

On to step 6:
312 can be fit into 3097 9 times, resulting in a remainder of 289.
Put 9 as the next digit of the answer. 
Result so far: 2589.0
Deduct 2808 from 3097 and we're left with 289.
Grab the next digit (5) from the dividend, add it to 289, then carry on: 2895 / 312

On to step 7:
When dividing 2895 by 312, we get 9 with a remainder of 87.
Record the quotient 9 as the next digit in the result. 
Result so far: 25899.0
Subtracting 2808 from 2895 leaves us with 87.
Bring next digit (6) of the dividend behind the 87 and repeat the process: 876 / 312

Let's proceed to step 8:
When dividing 876 by 312, we get 2 with a remainder of 252.
Put 2 as the next digit of the answer. 
Result so far: 258992.0
Subtracting 624 from 876 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 9:
312 goes into 2520 8 times with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 258992.8
Subtracting 2496 from 2520 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 10:
If we divide 240 by 312, we get 0 and a remainder of 240.
Write down 0 as next digit of the result. 
Result so far: 258992.8
Deduct 0 from 240 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 11:
The number 312 fits into 2400 7 times, leaving a remainder of 216.
Write down 7 as next digit of the result. 
Result so far: 258992.807
If we take 2184 away from 2400, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 12:
312 goes into 2160 6 times with a remainder of 288.
Record the quotient 6 as the next digit in the result. 
Result so far: 258992.8076
If we subtract 1872 from 2160, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Let's proceed to step 13:
If we divide 2880 by 312, we get 9 and a remainder of 72.
Put 9 as the next digit of the answer. 
Result so far: 258992.80769
Deduct 2808 from 2880 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 14:
If we divide 720 by 312, we get 2 and a remainder of 96.
Use 2 as the next digit of our solution. 
Result so far: 258992.807692
If we take 624 away from 720, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 15:
The number 312 fits into 960 3 times, leaving a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 258992.8076923
If we take 936 away from 960, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 16:
When dividing 240 by 312, we get 0 with a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 258992.8076923
Deduct 0 from 240 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Our division results in 258992.8076923 with a remaining 2.4e-07.
