We're dividing 390516 by 68 
We're looking to find how many times 68 goes into 390516.

Step 1:
68 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
If we take 0 away from 3, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 68

On to step 2:
68 goes into 39 0 times with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Take the next digit (0) from the dividend and append it to 39, then repeat: 390 / 68

Advancing to step 3:
68 can be fit into 390 5 times, resulting in a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 340 from 390 to get 50.
Take the next digit (5) from the dividend and append it to 50, then repeat: 505 / 68

Going ahead to step 4:
68 goes into 505 7 times with a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 57.0
If we subtract 476 from 505, we get 29.
Take the next digit (1) from the dividend and append it to 29, then repeat: 291 / 68

Advancing to step 5:
68 goes into 291 4 times with a remainder of 19.
The number 4 becomes the next digit in our result. 
Result so far: 574.0
If we subtract 272 from 291, we get 19.
Append the next digit (6) from the dividend to 19 and continue with: 196 / 68

Advancing to step 6:
196 divided by 68 is 2 with a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 5742.0
If we subtract 136 from 196, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 7:
When dividing 600 by 68, we get 8 with a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 5742.8
If we take 544 away from 600, we end up with 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 8:
68 can be fit into 560 8 times, resulting in a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 5742.88
Subtracting 544 from 560 leaves us with 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 5742.88, with a leftover of 0.016.
