We're dividing 144161 by 15 
We want to figure out the number of times 144161 can be divided by 15.

Let's proceed to step 1:
15 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 15

Advancing to step 2:
The number 15 fits into 14 0 times, leaving a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Append the next digit (4) from the dividend to 14 and continue with: 144 / 15

Going ahead to step 3:
15 can be fit into 144 9 times, resulting in a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 135 from 144 and we're left with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 15

Going ahead to step 4:
When dividing 91 by 15, we get 6 with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 96.0
If we take 90 away from 91, we end up with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 15

Going ahead to step 5:
The number 15 fits into 16 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 961.0
If we subtract 15 from 16, we get 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 15

On to step 6:
15 can be fit into 11 0 times, resulting in a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 9610.0
Subtract 0 from 11 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
When dividing 110 by 15, we get 7 with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 9610.7
Deduct 105 from 110 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
15 can be fit into 50 3 times, resulting in a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 9610.73
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 9610.733
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 9610.733, with a leftover of 0.0005.
