We look at the division of 89868430 by 15 
We're looking to find how many times 15 goes into 89868430.

Let's proceed to step 1:
15 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 15

Moving on to step 2:
The number 15 fits into 89 5 times, leaving a remainder of 14.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 75 from 89 and we're left with 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 15

Moving on to step 3:
15 can be fit into 148 9 times, resulting in a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 59.0
If we take 135 away from 148, we end up with 13.
Append the next digit (6) from the dividend to 13 and continue with: 136 / 15

Step 4:
136 divided by 15 is 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 599.0
Subtracting 135 from 136 leaves us with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 15

Let's proceed to step 5:
The number 15 fits into 18 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 5991.0
Subtract 15 from 18 to get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 15

On to step 6:
The number 15 fits into 34 2 times, leaving a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 59912.0
Deduct 30 from 34 and we're left with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 15

Step 7:
15 goes into 43 2 times with a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 599122.0
Subtract 30 from 43 to get 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 15

Going ahead to step 8:
The number 15 fits into 130 8 times, leaving a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 5991228.0
Subtract 120 from 130 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.

Step 9:
The number 15 fits into 100 6 times, leaving a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 5991228.6
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.

Moving on to step 10:
15 goes into 100 6 times with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 5991228.66
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.

In conclusion, the division gives 5991228.66 with a balance of 0.01.
