303104 ÷ 31 
Our goal is to divide 303104 by 31.

Going ahead to step 1:
If we divide 3 by 31, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 31

Moving on to step 2:
The number 31 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Include the next digit (3) from the dividend after 30, then repeat: 303 / 31

Let's proceed to step 3:
31 goes into 303 9 times with a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 279 from 303 leaves us with 24.
Fetch the next digit (1) from the dividend, attach it to 24 and continue: 241 / 31

Moving on to step 4:
241 divided by 31 is 7 with a remainder of 24.
The next digit of our result is 7. 
Result so far: 97.0
Subtracting 217 from 241 leaves us with 24.
Include the next digit (0) from the dividend after 24, then repeat: 240 / 31

Moving on to step 5:
If we divide 240 by 31, we get 7 and a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 977.0
Subtracting 217 from 240 leaves us with 23.
Bring next digit (4) of the dividend behind the 23 and repeat the process: 234 / 31

Let's proceed to step 6:
If we divide 234 by 31, we get 7 and a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 9777.0
The remainder is 17 after subtracting 217 from 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 7:
31 goes into 170 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 9777.5
If we take 155 away from 170, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
If we divide 150 by 31, we get 4 and a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 9777.54
The remainder is 26 after subtracting 124 from 150.
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:
When dividing 260 by 31, we get 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 9777.548
The remainder is 12 after subtracting 248 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
120 divided by 31 is 3 with a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 9777.5483
Subtracting 93 from 120 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 11:
31 goes into 270 8 times with a remainder of 22.
The next digit of our result is 8. 
Result so far: 9777.54838
If we subtract 248 from 270, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 12:
The number 31 fits into 220 7 times, leaving a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 9777.548387
If we subtract 217 from 220, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 13:
The number 31 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 9777.548387
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 14:
If we divide 300 by 31, we get 9 and a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 9777.54838709
If we subtract 279 from 300, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final outcome is 9777.54838709, with a leftover of 2.1e-08.
