We look at the division of 305143 by 8 
We want to figure out the number of times 305143 can be divided by 8.

Going ahead to step 1:
8 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 8

Advancing to step 2:
8 can be fit into 30 3 times, resulting in a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 24 away from 30, we end up with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 8

Moving on to step 3:
When dividing 65 by 8, we get 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
If we subtract 64 from 65, we get 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 8

On to step 4:
8 goes into 11 1 times with a remainder of 3.
The next digit of our result is 1. 
Result so far: 381.0
If we take 8 away from 11, we end up with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 8

Moving on to step 5:
When dividing 34 by 8, we get 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 3814.0
If we subtract 32 from 34, we get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 8

Let's proceed to step 6:
23 divided by 8 is 2 with a remainder of 7.
The next digit of our result is 2. 
Result so far: 38142.0
Subtract 16 from 23 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:
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: 38142.8
If we subtract 64 from 70, we 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.

Moving on to step 8:
60 divided by 8 is 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 38142.87
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.

Step 9:
8 can be fit into 40 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 38142.875
If we subtract 40 from 40, 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.

Going ahead to step 10:
When dividing 0 by 8, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 38142.875
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.

On to step 11:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 38142.875
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.

Our division results in 38142.875 with a remaining 0.0.
