Let's divide 11457 by 15
Let's see how many times 15 fits into 11457.

Going ahead to step 1:
1 divided by 15 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 15

Moving on to step 2:
15 can be fit into 11 0 times, resulting in a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 11 and we're left with 11.
Fetch the next digit (4) from the dividend, attach it to 11 and continue: 114 / 15

Moving on to step 3:
The number 15 fits into 114 7 times, leaving a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 105 from 114 and we're left with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 15

Advancing to step 4:
95 divided by 15 is 6 with a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 76.0
Subtract 90 from 95 to get 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 15

Moving on to step 5:
57 divided by 15 is 3 with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 763.0
The remainder is 12 after subtracting 45 from 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 6:
If we divide 120 by 15, we get 8 and a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 763.8
Subtract 120 from 120 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
When dividing 0 by 15, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 763.8
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
The number 15 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 763.8
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 763.8, with a leftover of 0.0.
