We're dividing 243517 by 31 
We're looking to find how many times 31 goes into 243517.

Let's proceed to step 1:
When dividing 2 by 31, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 31

Moving on 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
The remainder is 24 after subtracting 0 from 24.
Fetch the next digit (3) from the dividend, attach it to 24 and continue: 243 / 31

Advancing to step 3:
243 divided by 31 is 7 with a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 26 after subtracting 217 from 243.
Include the next digit (5) from the dividend after 26, then repeat: 265 / 31

Let's proceed to step 4:
The number 31 fits into 265 8 times, leaving a remainder of 17.
The next digit of our result is 8. 
Result so far: 78.0
If we take 248 away from 265, we end up with 17.
Include the next digit (1) from the dividend after 17, then repeat: 171 / 31

Going ahead to step 5:
When dividing 171 by 31, we get 5 with a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 785.0
Subtract 155 from 171 to get 16.
Append the next digit (7) from the dividend to 16 and continue with: 167 / 31

On to step 6:
The number 31 fits into 167 5 times, leaving a remainder of 12.
Put 5 as the next digit of the answer. 
Result so far: 7855.0
Subtract 155 from 167 to 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.

Going ahead to step 7:
When dividing 120 by 31, we get 3 with a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 7855.3
Deduct 93 from 120 and we're left 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 8:
31 goes into 270 8 times with a remainder of 22.
The next digit of our result is 8. 
Result so far: 7855.38
Subtract 248 from 270 to 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.

Moving on to step 9:
220 divided by 31 is 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 7855.387
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 10:
31 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 7855.387
Deduct 0 from 30 and we're left 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.

On to step 11:
If we divide 300 by 31, we get 9 and a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 7855.38709
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.

Let's proceed to step 12:
31 goes into 210 6 times with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 7855.387096
If we subtract 186 from 210, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 13:
240 divided by 31 is 7 with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 7855.3870967
The remainder is 23 after subtracting 217 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 14:
The number 31 fits into 230 7 times, leaving a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 7855.38709677
Subtracting 217 from 230 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 7855.38709677 with a remaining 1.3e-08.
