We're dividing 243491 by 31 
We want to divide 243491 by 31.

Step 1:
2 divided by 31 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 31

Advancing to step 2:
The number 31 fits into 24 0 times, leaving a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 24 leaves us with 24.
Bring next digit (3) of the dividend behind the 24 and repeat the process: 243 / 31

Let's proceed to step 3:
31 can be fit into 243 7 times, resulting in a remainder of 26.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 217 from 243, we get 26.
Fetch the next digit (4) from the dividend, attach it to 26 and continue: 264 / 31

Advancing to step 4:
If we divide 264 by 31, we get 8 and a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Subtracting 248 from 264 leaves us with 16.
Grab the next digit (9) from the dividend, add it to 16, then carry on: 169 / 31

Going ahead to step 5:
If we divide 169 by 31, we get 5 and a remainder of 14.
The number 5 becomes the next digit in our result. 
Result so far: 785.0
Subtract 155 from 169 to get 14.
Append the next digit (1) from the dividend to 14 and continue with: 141 / 31

Moving on to step 6:
When dividing 141 by 31, we get 4 with a remainder of 17.
The number 4 becomes the next digit in our result. 
Result so far: 7854.0
If we take 124 away from 141, 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.

Going ahead to step 7:
170 divided by 31 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 7854.5
Deduct 155 from 170 and we're left 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:
150 divided by 31 is 4 with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 7854.54
Subtracting 124 from 150 leaves us 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.

Let's proceed to step 9:
31 goes into 260 8 times with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 7854.548
Deduct 248 from 260 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
120 divided by 31 is 3 with a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 7854.5483
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.

On to step 11:
31 goes into 270 8 times with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 7854.54838
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.

Let's proceed to step 12:
31 can be fit into 220 7 times, resulting in a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 7854.548387
If we take 217 away from 220, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 13:
30 divided by 31 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 7854.548387
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 14:
300 divided by 31 is 9 with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 7854.54838709
Subtracting 279 from 300 leaves us 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 7854.54838709, and the remainder is 2.1e-08.
