Let's divide 23860 by 90
We want to divide 23860 by 90.

Step 1:
90 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 90

Step 2:
The number 90 fits into 23 0 times, leaving a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Fetch the next digit (8) from the dividend, attach it to 23 and continue: 238 / 90

On to step 3:
When dividing 238 by 90, we get 2 with a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 180 from 238 and we're left with 58.
Include the next digit (6) from the dividend after 58, then repeat: 586 / 90

Let's proceed to step 4:
If we divide 586 by 90, we get 6 and a remainder of 46.
Use 6 as the next digit of our solution. 
Result so far: 26.0
The remainder is 46 after subtracting 540 from 586.
Take the next digit (0) from the dividend and append it to 46, then repeat: 460 / 90

Let's proceed to step 5:
90 goes into 460 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 265.0
Deduct 450 from 460 and we're left 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.

Let's proceed to step 6:
100 divided by 90 is 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 265.1
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
When dividing 100 by 90, we get 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 265.11
If we subtract 90 from 100, we 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.

The final outcome is 265.11, with a leftover of 0.01.
