We look at the division of 686393 by 30 
We want to divide 686393 by 30.

Let's proceed to step 1:
The number 30 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 30

Let's proceed to step 2:
The number 30 fits into 68 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 60 away from 68, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 30

Step 3:
When dividing 86 by 30, we get 2 with a remainder of 26.
The next digit of our result is 2. 
Result so far: 22.0
Subtracting 60 from 86 leaves us with 26.
Fetch the next digit (3) from the dividend, attach it to 26 and continue: 263 / 30

Step 4:
30 can be fit into 263 8 times, resulting in a remainder of 23.
Use 8 as the next digit of our solution. 
Result so far: 228.0
The remainder is 23 after subtracting 240 from 263.
Grab the next digit (9) from the dividend, add it to 23, then carry on: 239 / 30

Moving on to step 5:
When dividing 239 by 30, we get 7 with a remainder of 29.
Record the quotient 7 as the next digit in the result. 
Result so far: 2287.0
Deduct 210 from 239 and we're left with 29.
Append the next digit (3) from the dividend to 29 and continue with: 293 / 30

Going ahead to step 6:
30 can be fit into 293 9 times, resulting in a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 22879.0
Deduct 270 from 293 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 7:
If we divide 230 by 30, we get 7 and a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 22879.7
Subtracting 210 from 230 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.

Let's proceed to step 8:
When dividing 200 by 30, we get 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 22879.76
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
30 goes into 200 6 times with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 22879.766
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 22879.766 with a balance of 0.002.
