310317 ÷ 23 
We want to figure out the number of times 310317 can be divided by 23.

Moving on to step 1:
23 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 23

Step 2:
23 goes into 31 1 times with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 23 from 31 to get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 23

Moving on to step 3:
23 can be fit into 80 3 times, resulting in a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 69 from 80 leaves us with 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 23

Advancing to step 4:
When dividing 113 by 23, we get 4 with a remainder of 21.
Use 4 as the next digit of our solution. 
Result so far: 134.0
Subtracting 92 from 113 leaves us with 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 23

Going ahead to step 5:
The number 23 fits into 211 9 times, leaving a remainder of 4.
The next digit of our result is 9. 
Result so far: 1349.0
Subtracting 207 from 211 leaves us with 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 23

Going ahead to step 6:
If we divide 47 by 23, we get 2 and a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 13492.0
Deduct 46 from 47 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
23 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 13492.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
If we divide 100 by 23, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 13492.04
Subtracting 92 from 100 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
23 goes into 80 3 times with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 13492.043
If we take 69 away from 80, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 10:
23 can be fit into 110 4 times, resulting in a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 13492.0434
Subtracting 92 from 110 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
180 divided by 23 is 7 with a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 13492.04347
If we take 161 away from 180, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 12:
23 goes into 190 8 times with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 13492.043478
Subtracting 184 from 190 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 13:
The number 23 fits into 60 2 times, leaving a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 13492.0434782
If we take 46 away from 60, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 14:
If we divide 140 by 23, we get 6 and a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 13492.04347826
If we take 138 away from 140, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 13492.04347826 with a remaining 2e-09.
