343019 divided by 8 
We want to divide 343019 by 8.

Advancing to step 1:
8 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 8

Going ahead to step 2:
When dividing 34 by 8, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 32 away from 34, we end up with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 8

Let's proceed to step 3:
8 goes into 23 2 times with a remainder of 7.
The next digit of our result is 2. 
Result so far: 42.0
If we take 16 away from 23, we end up with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 8

Going ahead to step 4:
8 can be fit into 70 8 times, resulting in a remainder of 6.
The next digit of our result is 8. 
Result so far: 428.0
The remainder is 6 after subtracting 64 from 70.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 8

Advancing to step 5:
When dividing 61 by 8, we get 7 with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 4287.0
Subtract 56 from 61 to get 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 8

Let's proceed to step 6:
When dividing 59 by 8, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 42877.0
Subtract 56 from 59 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
The number 8 fits into 30 3 times, leaving a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 42877.3
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.

On to step 8:
8 goes into 60 7 times with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 42877.37
The remainder is 4 after subtracting 56 from 60.
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:
The number 8 fits into 40 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 42877.375
If we take 40 away from 40, 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.

On 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: 42877.375
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:
The number 8 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 42877.375
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.

After the division, we end up with 42877.375 and a remainder of 0.0.
