102303 ÷ 8 
Let's see how many times 8 fits into 102303.

Step 1:
If we divide 1 by 8, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 8

Advancing to step 2:
The number 8 fits into 10 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 8 from 10, we get 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 8

Advancing to step 3:
When dividing 22 by 8, we get 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 16 away from 22, we end up with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 8

Let's proceed to step 4:
8 can be fit into 63 7 times, resulting in a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 127.0
Deduct 56 from 63 and we're left with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 8

Advancing to step 5:
70 divided by 8 is 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 1278.0
Subtract 64 from 70 to get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 8

Step 6:
8 goes into 63 7 times with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 12787.0
Subtract 56 from 63 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
If we divide 70 by 8, we get 8 and a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 12787.8
The remainder is 6 after subtracting 64 from 70.
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:
If we divide 60 by 8, we get 7 and a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 12787.87
Subtracting 56 from 60 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
8 can be fit into 40 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 12787.875
Subtract 40 from 40 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.

Advancing to step 10:
If we divide 0 by 8, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12787.875
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.

Let's proceed to step 11:
If we divide 0 by 8, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12787.875
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 quotient of the division is 12787.875, and the remainder is 0.0.
