We're dividing 148203 by 8 
We're looking to find how many times 8 goes into 148203.

Going ahead to step 1:
8 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 8

Let's proceed to step 2:
If we divide 14 by 8, we get 1 and a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 8 from 14, we get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 8

Step 3:
8 can be fit into 68 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtract 64 from 68 to get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 8

Step 4:
The number 8 fits into 42 5 times, leaving a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 185.0
Deduct 40 from 42 and we're left with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 8

Step 5:
When dividing 20 by 8, we get 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 1852.0
Deduct 16 from 20 and we're left with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 8

Step 6:
When dividing 43 by 8, we get 5 with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 18525.0
Subtracting 40 from 43 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.

Let's proceed to step 7:
30 divided by 8 is 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 18525.3
If we take 24 away from 30, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
The number 8 fits into 60 7 times, leaving a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 18525.37
Subtract 56 from 60 to 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.

Moving on to step 9:
40 divided by 8 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 18525.375
Subtracting 40 from 40 leaves us 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:
If we divide 0 by 8, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 18525.375
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.

Moving on to step 11:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18525.375
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.

The final result is 18525.375 with a remainder of 0.0.
