We're dividing 991584 by 23 
Our goal is to divide 991584 by 23.

Going ahead to step 1:
23 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 23

Moving on to step 2:
The number 23 fits into 99 4 times, leaving a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 92 from 99 and we're left with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 23

Going ahead to step 3:
71 divided by 23 is 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Subtracting 69 from 71 leaves us with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 23

Going ahead to step 4:
25 divided by 23 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 431.0
If we subtract 23 from 25, we get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 23

Let's proceed to step 5:
The number 23 fits into 28 1 times, leaving a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 4311.0
Subtracting 23 from 28 leaves us with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 23

On to step 6:
The number 23 fits into 54 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 43112.0
Deduct 46 from 54 and we're left 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.

Let's proceed to step 7:
If we divide 80 by 23, we get 3 and a remainder of 11.
The next digit of our result is 3. 
Result so far: 43112.3
Deduct 69 from 80 and we're left 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.

Step 8:
23 can be fit into 110 4 times, resulting in a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 43112.34
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.

Step 9:
If we divide 180 by 23, we get 7 and a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 43112.347
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 10:
190 divided by 23 is 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 43112.3478
If we take 184 away from 190, we end up 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.

Step 11:
23 goes into 60 2 times with a remainder of 14.
The next digit of our result is 2. 
Result so far: 43112.34782
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.

On to step 12:
23 goes into 140 6 times with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 43112.347826
If we subtract 138 from 140, we 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.

Advancing to step 13:
23 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 43112.347826
Subtracting 0 from 20 leaves us with 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 14:
The number 23 fits into 200 8 times, leaving a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 43112.34782608
Subtracting 184 from 200 leaves us 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.

The final result is 43112.34782608 with a remainder of 1.6e-08.
