439821 ÷ 68 
We want to divide 439821 by 68.

Going ahead to step 1:
4 divided by 68 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 68

Going ahead to step 2:
68 can be fit into 43 0 times, resulting in a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Append the next digit (9) from the dividend to 43 and continue with: 439 / 68

Moving on to step 3:
If we divide 439 by 68, we get 6 and a remainder of 31.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 408 from 439 to get 31.
Append the next digit (8) from the dividend to 31 and continue with: 318 / 68

Let's proceed to step 4:
If we divide 318 by 68, we get 4 and a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
If we subtract 272 from 318, we get 46.
Bring next digit (2) of the dividend behind the 46 and repeat the process: 462 / 68

Moving on to step 5:
68 goes into 462 6 times with a remainder of 54.
Put 6 as the next digit of the answer. 
Result so far: 646.0
If we take 408 away from 462, we end up with 54.
Fetch the next digit (1) from the dividend, attach it to 54 and continue: 541 / 68

Advancing to step 6:
541 divided by 68 is 7 with a remainder of 65.
The next digit of our result is 7. 
Result so far: 6467.0
The remainder is 65 after subtracting 476 from 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 7:
68 can be fit into 650 9 times, resulting in a remainder of 38.
Put 9 as the next digit of the answer. 
Result so far: 6467.9
If we subtract 612 from 650, we get 38.
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 8:
380 divided by 68 is 5 with a remainder of 40.
The next digit of our result is 5. 
Result so far: 6467.95
If we take 340 away from 380, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
400 divided by 68 is 5 with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 6467.955
If we take 340 away from 400, we end up with 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 result is 6467.955 with a remainder of 0.006.
