43143 divided by 8 
We want to figure out the number of times 43143 can be divided by 8.

Step 1:
When dividing 4 by 8, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 8

Let's proceed to step 2:
43 divided by 8 is 5 with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 40 from 43 leaves us with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 8

Going ahead to step 3:
When dividing 31 by 8, we get 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
Subtract 24 from 31 to get 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 8

Going ahead to step 4:
8 can be fit into 74 9 times, resulting in a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 539.0
If we take 72 away from 74, we end up with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 8

Step 5:
The number 8 fits into 23 2 times, leaving a remainder of 7.
The next digit of our result is 2. 
Result so far: 5392.0
The remainder is 7 after subtracting 16 from 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 6:
8 can be fit into 70 8 times, resulting in a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 5392.8
Subtract 64 from 70 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.

Moving on to step 7:
When dividing 60 by 8, we get 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 5392.87
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.

Step 8:
If we divide 40 by 8, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5392.875
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.

Moving on to step 9:
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: 5392.875
Subtracting 0 from 0 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.

Going ahead to step 10:
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: 5392.875
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.

The final outcome is 5392.875, with a leftover of 0.0.
