We look at the division of 996309 by 23 
Let's see how many times 23 fits into 996309.

Going ahead to step 1:
9 divided by 23 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 23

On to step 2:
99 divided by 23 is 4 with a remainder of 7.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 7 after subtracting 92 from 99.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 23

On to step 3:
23 goes into 76 3 times with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Deduct 69 from 76 and we're left with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 23

On to step 4:
If we divide 73 by 23, we get 3 and a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 433.0
If we subtract 69 from 73, we get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 23

Advancing to step 5:
The number 23 fits into 40 1 times, leaving a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 4331.0
Subtracting 23 from 40 leaves us with 17.
Include the next digit (9) from the dividend after 17, then repeat: 179 / 23

Let's proceed to step 6:
When dividing 179 by 23, we get 7 with a remainder of 18.
The next digit of our result is 7. 
Result so far: 43317.0
Deduct 161 from 179 and we're left 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.

Moving on to step 7:
The number 23 fits into 180 7 times, leaving a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 43317.7
Subtracting 161 from 180 leaves us 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.

Let's proceed to step 8:
23 goes into 190 8 times with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 43317.78
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.

Let's proceed to step 9:
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: 43317.782
The remainder is 14 after subtracting 46 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
23 can be fit into 140 6 times, resulting in a remainder of 2.
The next digit of our result is 6. 
Result so far: 43317.7826
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.

On to step 11:
The number 23 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 43317.7826
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
When dividing 200 by 23, we get 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 43317.782608
Deduct 184 from 200 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
The number 23 fits into 160 6 times, leaving a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 43317.7826086
If we take 138 away from 160, we end up 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.

Step 14:
23 goes into 220 9 times with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 43317.78260869
Subtract 207 from 220 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 43317.78260869 and a remainder of 1.3e-08.
