128989 divided by 23 
We want to divide 128989 by 23.

Going ahead to step 1:
23 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 23

Step 2:
When dividing 12 by 23, we get 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 23

Let's proceed to step 3:
The number 23 fits into 128 5 times, leaving a remainder of 13.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 115 from 128, we get 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 23

Advancing to step 4:
23 can be fit into 139 6 times, resulting in a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
Subtract 138 from 139 to get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 23

Going ahead to step 5:
23 can be fit into 18 0 times, resulting in a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 560.0
The remainder is 18 after subtracting 0 from 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 23

Step 6:
If we divide 189 by 23, we get 8 and a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 5608.0
Subtract 184 from 189 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
50 divided by 23 is 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 5608.2
If we subtract 46 from 50, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
If we divide 40 by 23, we get 1 and a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 5608.21
Subtract 23 from 40 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 9:
23 can be fit into 170 7 times, resulting in a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 5608.217
If we take 161 away from 170, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 10:
The number 23 fits into 90 3 times, leaving a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 5608.2173
Deduct 69 from 90 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.

Step 11:
23 can be fit into 210 9 times, resulting in a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 5608.21739
The remainder is 3 after subtracting 207 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 12:
30 divided by 23 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 5608.217391
If we take 23 away from 30, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 13:
The number 23 fits into 70 3 times, leaving a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 5608.2173913
If we take 69 away from 70, we end up 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.

Let's proceed to step 14:
10 divided by 23 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 5608.2173913
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 5608.2173913 with a remaining 1e-08.
