Let's divide 80315033 by 310
Our goal is to divide 80315033 by 310.

On to step 1:
8 divided by 310 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
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 / 310

Advancing to step 2:
310 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Append the next digit (3) from the dividend to 80 and continue with: 803 / 310

Going ahead to step 3:
If we divide 803 by 310, we get 2 and a remainder of 183.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 620 from 803 leaves us with 183.
Include the next digit (1) from the dividend after 183, then repeat: 1831 / 310

Going ahead to step 4:
When dividing 1831 by 310, we get 5 with a remainder of 281.
Use 5 as the next digit of our solution. 
Result so far: 25.0
The remainder is 281 after subtracting 1550 from 1831.
Bring next digit (5) of the dividend behind the 281 and repeat the process: 2815 / 310

Step 5:
310 can be fit into 2815 9 times, resulting in a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 259.0
Subtract 2790 from 2815 to get 25.
Grab the next digit (0) from the dividend, add it to 25, then carry on: 250 / 310

On to step 6:
310 goes into 250 0 times with a remainder of 250.
The next digit of our result is 0. 
Result so far: 2590.0
If we subtract 0 from 250, we get 250.
Fetch the next digit (3) from the dividend, attach it to 250 and continue: 2503 / 310

Let's proceed to step 7:
If we divide 2503 by 310, we get 8 and a remainder of 23.
Use 8 as the next digit of our solution. 
Result so far: 25908.0
Subtracting 2480 from 2503 leaves us with 23.
Append the next digit (3) from the dividend to 23 and continue with: 233 / 310

Going ahead to step 8:
When dividing 233 by 310, we get 0 with a remainder of 233.
The number 0 becomes the next digit in our result. 
Result so far: 259080.0
The remainder is 233 after subtracting 0 from 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Step 9:
310 can be fit into 2330 7 times, resulting in a remainder of 160.
The next digit of our result is 7. 
Result so far: 259080.7
Deduct 2170 from 2330 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 10:
The number 310 fits into 1600 5 times, leaving a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 259080.75
Subtract 1550 from 1600 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
The number 310 fits into 500 1 times, leaving a remainder of 190.
Put 1 as the next digit of the answer. 
Result so far: 259080.751
The remainder is 190 after subtracting 310 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 12:
310 goes into 1900 6 times with a remainder of 40.
The next digit of our result is 6. 
Result so far: 259080.7516
Deduct 1860 from 1900 and we're left 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.

Let's proceed to step 13:
If we divide 400 by 310, we get 1 and a remainder of 90.
Record the quotient 1 as the next digit in the result. 
Result so far: 259080.75161
If we subtract 310 from 400, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 14:
310 goes into 900 2 times with a remainder of 280.
Write down 2 as next digit of the result. 
Result so far: 259080.751612
Subtracting 620 from 900 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 15:
If we divide 2800 by 310, we get 9 and a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 259080.7516129
If we subtract 2790 from 2800, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 16:
When dividing 100 by 310, we get 0 with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 259080.7516129
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 259080.7516129 with a remainder of 1e-07.
