324215 ÷ 31 
Let's see how many times 31 fits into 324215.

Step 1:
31 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 31

On to step 2:
The number 31 fits into 32 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 31 from 32 and we're left with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 31

Moving on to step 3:
The number 31 fits into 14 0 times, leaving a remainder of 14.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 14 leaves us with 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 31

Advancing to step 4:
If we divide 142 by 31, we get 4 and a remainder of 18.
The next digit of our result is 4. 
Result so far: 104.0
If we take 124 away from 142, we end up with 18.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 31

On to step 5:
31 can be fit into 181 5 times, resulting in a remainder of 26.
Put 5 as the next digit of the answer. 
Result so far: 1045.0
If we take 155 away from 181, we end up with 26.
Take the next digit (5) from the dividend and append it to 26, then repeat: 265 / 31

Going ahead to step 6:
31 goes into 265 8 times with a remainder of 17.
The number 8 becomes the next digit in our result. 
Result so far: 10458.0
If we take 248 away from 265, we end up with 17.
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:
When dividing 170 by 31, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 10458.5
Subtracting 155 from 170 leaves us 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.

On to step 8:
When dividing 150 by 31, we get 4 with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 10458.54
Deduct 124 from 150 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 9:
31 can be fit into 260 8 times, resulting in a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 10458.548
If we subtract 248 from 260, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
The number 31 fits into 120 3 times, leaving a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 10458.5483
If we take 93 away from 120, we end up 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.

Advancing to step 11:
31 goes into 270 8 times with a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 10458.54838
Subtracting 248 from 270 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 12:
When dividing 220 by 31, we get 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 10458.548387
The remainder is 3 after subtracting 217 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 13:
The number 31 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 10458.548387
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 14:
31 goes into 300 9 times with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 10458.54838709
Deduct 279 from 300 and we're left with 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 quotient of the division is 10458.54838709, and the remainder is 2.1e-08.
