Let's divide 103003 by 8
Let's see how many times 8 fits into 103003.

Let's proceed to 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
Subtracting 0 from 1 leaves us with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 8

Going ahead to step 2:
The number 8 fits into 10 1 times, leaving a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 8 from 10 leaves us with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 8

Advancing to step 3:
If we divide 23 by 8, we get 2 and a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 16 from 23, we get 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 8

Step 4:
8 goes into 70 8 times with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 128.0
Subtract 64 from 70 to get 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 8

Step 5:
60 divided by 8 is 7 with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 1287.0
If we take 56 away from 60, we end up with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 8

On to step 6:
If we divide 43 by 8, we get 5 and a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 12875.0
If we take 40 away from 43, we end up 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.

On to step 7:
The number 8 fits into 30 3 times, leaving a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 12875.3
The remainder is 6 after subtracting 24 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
If we divide 60 by 8, we get 7 and a remainder of 4.
The next digit of our result is 7. 
Result so far: 12875.37
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:
When dividing 40 by 8, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 12875.375
The remainder is 0 after subtracting 40 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12875.375
If we subtract 0 from 0, we 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 11:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12875.375
If we subtract 0 from 0, we 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.

Our division results in 12875.375 with a remaining 0.0.
