150515 ÷ 8 
Let's see how many times 8 fits into 150515.

Step 1:
8 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 8

On to step 2:
8 can be fit into 15 1 times, resulting in a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 8 from 15 and we're left with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 8

Step 3:
8 goes into 70 8 times with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
The remainder is 6 after subtracting 64 from 70.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 8

On to step 4:
If we divide 65 by 8, we get 8 and a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 188.0
Subtract 64 from 65 to get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 8

Advancing to step 5:
When dividing 11 by 8, we get 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1881.0
The remainder is 3 after subtracting 8 from 11.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 8

Advancing to step 6:
35 divided by 8 is 4 with a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 18814.0
Subtracting 32 from 35 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
When dividing 30 by 8, we get 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 18814.3
Subtract 24 from 30 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
60 divided by 8 is 7 with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 18814.37
If we subtract 56 from 60, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
The number 8 fits into 40 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 18814.375
Deduct 40 from 40 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 10:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 18814.375
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.

Step 11:
8 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 18814.375
Subtract 0 from 0 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.

The quotient of the division is 18814.375, and the remainder is 0.0.
