We look at the division of 148486 by 15 
Let's see how many times 15 fits into 148486.

Advancing to step 1:
If we divide 1 by 15, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 15

Going ahead to step 2:
15 goes into 14 0 times with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 15

On to step 3:
The number 15 fits into 148 9 times, leaving a remainder of 13.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 13 after subtracting 135 from 148.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 15

Moving on to step 4:
134 divided by 15 is 8 with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
If we take 120 away from 134, we end up with 14.
Take the next digit (8) from the dividend and append it to 14, then repeat: 148 / 15

On to step 5:
15 can be fit into 148 9 times, resulting in a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 989.0
If we take 135 away from 148, we end up with 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 15

Let's proceed to step 6:
15 goes into 136 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 9899.0
If we subtract 135 from 136, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
15 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 9899.0
If we take 0 away from 10, 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.

Advancing to step 8:
When dividing 100 by 15, we get 6 with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 9899.06
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.

Moving on to 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: 9899.066
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 final outcome is 9899.066, with a leftover of 0.001.
