121463 ÷ 15 
Our goal is to divide 121463 by 15.

Step 1:
15 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 15

Going ahead to step 2:
If we divide 12 by 15, we get 0 and a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 15

On to step 3:
15 can be fit into 121 8 times, resulting in a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 120 away from 121, we end up with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 15

Let's proceed to step 4:
If we divide 14 by 15, we get 0 and a remainder of 14.
The next digit of our result is 0. 
Result so far: 80.0
The remainder is 14 after subtracting 0 from 14.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 15

Let's proceed to step 5:
If we divide 146 by 15, we get 9 and a remainder of 11.
The next digit of our result is 9. 
Result so far: 809.0
Subtracting 135 from 146 leaves us with 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 15

Moving on to step 6:
113 divided by 15 is 7 with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 8097.0
The remainder is 8 after subtracting 105 from 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
When dividing 80 by 15, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 8097.5
If we take 75 away from 80, 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.

Step 8:
50 divided by 15 is 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 8097.53
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
15 goes into 50 3 times with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 8097.533
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.

After the division, we end up with 8097.533 and a remainder of 0.0005.
