Let's divide 186389 by 23
Let's see how many times 23 fits into 186389.

Moving on to step 1:
If we divide 1 by 23, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 23

Moving on 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
If we take 0 away from 18, we end up with 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 23

Going ahead to step 3:
23 goes into 186 8 times with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 184 from 186 leaves us with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 23

Advancing to step 4:
23 can be fit into 23 1 times, resulting in a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
Subtracting 23 from 23 leaves us with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 23

Let's proceed to step 5:
23 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 810.0
If we take 0 away from 8, we end up with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 23

Let's proceed to step 6:
23 can be fit into 89 3 times, resulting in a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 8103.0
If we take 69 away from 89, we end up 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.

Going ahead to step 7:
When dividing 200 by 23, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 8103.8
Subtract 184 from 200 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
The number 23 fits into 160 6 times, leaving a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 8103.86
Deduct 138 from 160 and we're left 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.

Going ahead to step 9:
23 can be fit into 220 9 times, resulting in a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 8103.869
Subtracting 207 from 220 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 10:
23 can be fit into 130 5 times, resulting in a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 8103.8695
Deduct 115 from 130 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 11:
23 goes into 150 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 8103.86956
Deduct 138 from 150 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
When dividing 120 by 23, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 8103.869565
Deduct 115 from 120 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 13:
When dividing 50 by 23, we get 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 8103.8695652
If we take 46 away from 50, we end up with 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 14:
When dividing 40 by 23, we get 1 with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 8103.86956521
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.

The final result is 8103.86956521 with a remainder of 1.7e-08.
