236389 divided by 15 
We want to figure out the number of times 236389 can be divided by 15.

Let's proceed to step 1:
2 divided by 15 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 15

Step 2:
15 goes into 23 1 times with a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 15 from 23 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 15

On to step 3:
The number 15 fits into 86 5 times, leaving a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 75 from 86 to get 11.
Bring next digit (3) of the dividend behind the 11 and repeat the process: 113 / 15

Step 4:
If we divide 113 by 15, we get 7 and a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 157.0
If we take 105 away from 113, we end up with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 15

Moving on to step 5:
When dividing 88 by 15, we get 5 with a remainder of 13.
The next digit of our result is 5. 
Result so far: 1575.0
Subtracting 75 from 88 leaves us with 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 15

Step 6:
If we divide 139 by 15, we get 9 and a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 15759.0
Deduct 135 from 139 and we're left 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 7:
15 can be fit into 40 2 times, resulting in a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 15759.2
Deduct 30 from 40 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.

Moving on to step 8:
15 goes into 100 6 times with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 15759.26
Subtract 90 from 100 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.

Let's proceed to step 9:
100 divided by 15 is 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 15759.266
If we take 90 away from 100, 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.

After the division, we end up with 15759.266 and a remainder of 0.001.
