We're dividing 389089 by 15 
We want to figure out the number of times 389089 can be divided by 15.

Moving on to step 1:
15 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 15

Let's proceed to step 2:
The number 15 fits into 38 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 8 after subtracting 30 from 38.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 15

Advancing to step 3:
When dividing 89 by 15, we get 5 with a remainder of 14.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Deduct 75 from 89 and we're left with 14.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 15

Going ahead to step 4:
The number 15 fits into 140 9 times, leaving a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 259.0
The remainder is 5 after subtracting 135 from 140.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 15

Going ahead to step 5:
58 divided by 15 is 3 with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 2593.0
Deduct 45 from 58 and we're left with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 15

Advancing to step 6:
When dividing 139 by 15, we get 9 with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 25939.0
If we subtract 135 from 139, 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.

On to step 7:
When dividing 40 by 15, we get 2 with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 25939.2
Subtracting 30 from 40 leaves us 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.

Advancing to step 8:
100 divided by 15 is 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 25939.26
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:
When dividing 100 by 15, we get 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 25939.266
Deduct 90 from 100 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.

The quotient of the division is 25939.266, and the remainder is 0.001.
