We're dividing 668138 by 68 
Let's see how many times 68 fits into 668138.

Advancing to step 1:
68 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 68

Going ahead to step 2:
When dividing 66 by 68, we get 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Fetch the next digit (8) from the dividend, attach it to 66 and continue: 668 / 68

Step 3:
668 divided by 68 is 9 with a remainder of 56.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 612 from 668 to get 56.
Bring next digit (1) of the dividend behind the 56 and repeat the process: 561 / 68

Advancing to step 4:
When dividing 561 by 68, we get 8 with a remainder of 17.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
If we subtract 544 from 561, we get 17.
Take the next digit (3) from the dividend and append it to 17, then repeat: 173 / 68

Let's proceed to step 5:
When dividing 173 by 68, we get 2 with a remainder of 37.
The number 2 becomes the next digit in our result. 
Result so far: 982.0
The remainder is 37 after subtracting 136 from 173.
Grab the next digit (8) from the dividend, add it to 37, then carry on: 378 / 68

Going ahead to step 6:
68 can be fit into 378 5 times, resulting in a remainder of 38.
The number 5 becomes the next digit in our result. 
Result so far: 9825.0
The remainder is 38 after subtracting 340 from 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 7:
When dividing 380 by 68, we get 5 with a remainder of 40.
The next digit of our result is 5. 
Result so far: 9825.5
If we subtract 340 from 380, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
If we divide 400 by 68, we get 5 and a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 9825.55
If we subtract 340 from 400, 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.

The final outcome is 9825.55, with a leftover of 0.06.
