304420 divided by 31 
We're looking to find how many times 31 goes into 304420.

Moving on to step 1:
The number 31 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 31

Moving on to step 2:
31 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 31

Let's proceed to step 3:
31 goes into 304 9 times with a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 279 from 304 to get 25.
Append the next digit (4) from the dividend to 25 and continue with: 254 / 31

Let's proceed to step 4:
The number 31 fits into 254 8 times, leaving a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 98.0
The remainder is 6 after subtracting 248 from 254.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 31

On to step 5:
When dividing 62 by 31, we get 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 982.0
The remainder is 0 after subtracting 62 from 62.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 31

On to step 6:
If we divide 0 by 31, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9820.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
If we divide 0 by 31, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9820.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
0 divided by 31 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9820.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 9820.0 and a remainder of 0.0.
