We're dividing 426821 by 68 
Let's see how many times 68 fits into 426821.

On to step 1:
If we divide 4 by 68, we get 0 and 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.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 68

Going ahead to step 2:
If we divide 42 by 68, we get 0 and a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Bring next digit (6) of the dividend behind the 42 and repeat the process: 426 / 68

Step 3:
68 can be fit into 426 6 times, resulting in a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 408 from 426, we get 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 68

Moving on to step 4:
When dividing 188 by 68, we get 2 with a remainder of 52.
Use 2 as the next digit of our solution. 
Result so far: 62.0
Deduct 136 from 188 and we're left with 52.
Grab the next digit (2) from the dividend, add it to 52, then carry on: 522 / 68

Step 5:
68 goes into 522 7 times with a remainder of 46.
Put 7 as the next digit of the answer. 
Result so far: 627.0
Deduct 476 from 522 and we're left with 46.
Fetch the next digit (1) from the dividend, attach it to 46 and continue: 461 / 68

Going ahead to step 6:
68 goes into 461 6 times with a remainder of 53.
Put 6 as the next digit of the answer. 
Result so far: 6276.0
Subtracting 408 from 461 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 7:
530 divided by 68 is 7 with a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 6276.7
Deduct 476 from 530 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 8:
68 goes into 540 7 times with a remainder of 64.
The next digit of our result is 7. 
Result so far: 6276.77
Subtracting 476 from 540 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 6276.77 with a remainder of 0.064.
