309811 divided by 23 
We want to divide 309811 by 23.

Moving on to step 1:
The number 23 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 23

Let's proceed to step 2:
If we divide 30 by 23, we get 1 and a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 23 from 30 to get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 23

Going ahead to step 3:
If we divide 79 by 23, we get 3 and a remainder of 10.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 69 from 79 leaves us with 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 23

Going ahead to step 4:
23 goes into 108 4 times with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 134.0
Subtract 92 from 108 to get 16.
Append the next digit (1) from the dividend to 16 and continue with: 161 / 23

Step 5:
161 divided by 23 is 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 1347.0
Subtract 161 from 161 to get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 23

Advancing to step 6:
If we divide 1 by 23, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 13470.0
The remainder is 1 after subtracting 0 from 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
The number 23 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 13470.0
If we take 0 away from 10, we end up 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.

Let's proceed to step 8:
If we divide 100 by 23, we get 4 and a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 13470.04
If we take 92 away from 100, we end up 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.

On to step 9:
80 divided by 23 is 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 13470.043
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.

Let's proceed to step 10:
When dividing 110 by 23, we get 4 with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 13470.0434
If we take 92 away from 110, we end up 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:
23 goes into 180 7 times with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 13470.04347
The remainder is 19 after subtracting 161 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 12:
The number 23 fits into 190 8 times, leaving a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 13470.043478
If we subtract 184 from 190, we get 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:
When dividing 60 by 23, we get 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 13470.0434782
Subtract 46 from 60 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 14:
The number 23 fits into 140 6 times, leaving a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 13470.04347826
Subtract 138 from 140 to get 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 13470.04347826 with a remaining 2e-09.
