We look at the division of 434390 by 68 
We're looking to find how many times 68 goes into 434390.

Step 1:
If we divide 4 by 68, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 68

Going ahead to step 2:
43 divided by 68 is 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Fetch the next digit (4) from the dividend, attach it to 43 and continue: 434 / 68

Going ahead to step 3:
When dividing 434 by 68, we get 6 with a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 26 after subtracting 408 from 434.
Include the next digit (3) from the dividend after 26, then repeat: 263 / 68

On to step 4:
If we divide 263 by 68, we get 3 and a remainder of 59.
Use 3 as the next digit of our solution. 
Result so far: 63.0
Subtracting 204 from 263 leaves us with 59.
Fetch the next digit (9) from the dividend, attach it to 59 and continue: 599 / 68

Moving on to step 5:
The number 68 fits into 599 8 times, leaving a remainder of 55.
Use 8 as the next digit of our solution. 
Result so far: 638.0
Deduct 544 from 599 and we're left with 55.
Take the next digit (0) from the dividend and append it to 55, then repeat: 550 / 68

Advancing to step 6:
550 divided by 68 is 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 6388.0
Subtract 544 from 550 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.

Advancing to step 7:
68 goes into 60 0 times with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 6388.0
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 8:
68 can be fit into 600 8 times, resulting in a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 6388.08
If we subtract 544 from 600, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 9:
68 goes into 560 8 times with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 6388.088
Subtract 544 from 560 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 6388.088, with a leftover of 0.0016.
