We look at the division of 678839 by 30 
We want to divide 678839 by 30.

Going ahead to step 1:
6 divided by 30 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 30

Advancing to step 2:
The number 30 fits into 67 2 times, leaving a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 60 from 67 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 30

Advancing to step 3:
If we divide 78 by 30, we get 2 and a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Deduct 60 from 78 and we're left with 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 30

Step 4:
30 goes into 188 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 226.0
If we take 180 away from 188, we end up with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 30

Going ahead to step 5:
83 divided by 30 is 2 with a remainder of 23.
Put 2 as the next digit of the answer. 
Result so far: 2262.0
If we take 60 away from 83, we end up with 23.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 30

On to step 6:
The number 30 fits into 239 7 times, leaving a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 22627.0
If we take 210 away from 239, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 7:
The number 30 fits into 290 9 times, leaving a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 22627.9
Subtracting 270 from 290 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
If we divide 200 by 30, we get 6 and a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 22627.96
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
200 divided by 30 is 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 22627.966
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 22627.966, and the remainder is 0.002.
