We divide 189987 by 23
We want to figure out the number of times 189987 can be divided by 23.

Advancing to step 1:
23 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 23

Let's proceed to step 2:
If we divide 18 by 23, we get 0 and a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Fetch the next digit (9) from the dividend, attach it to 18 and continue: 189 / 23

Advancing to step 3:
189 divided by 23 is 8 with a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 184 from 189, we get 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 23

Going ahead to step 4:
23 can be fit into 59 2 times, resulting in a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
Deduct 46 from 59 and we're left with 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 23

Moving on to step 5:
23 can be fit into 138 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 826.0
If we subtract 138 from 138, we get 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 23

Step 6:
23 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 8260.0
Deduct 0 from 7 and we're left 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.

Going ahead to step 7:
The number 23 fits into 70 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 8260.3
Subtract 69 from 70 to get 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 8:
23 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 8260.3
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.

On to step 9:
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: 8260.304
Deduct 92 from 100 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.

On to step 10:
If we divide 80 by 23, we get 3 and a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 8260.3043
Subtract 69 from 80 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 11:
110 divided by 23 is 4 with a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 8260.30434
If we subtract 92 from 110, we get 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 12:
If we divide 180 by 23, we get 7 and a remainder of 19.
The next digit of our result is 7. 
Result so far: 8260.304347
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.

Advancing to step 13:
23 can be fit into 190 8 times, resulting in a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 8260.3043478
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.

Moving on to step 14:
23 goes into 60 2 times with a remainder of 14.
The next digit of our result is 2. 
Result so far: 8260.30434782
If we subtract 46 from 60, we 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.

Our division results in 8260.30434782 with a remaining 1.4e-08.
