We look at the division of 686890 by 30 
We're looking to find how many times 30 goes into 686890.

Going ahead to step 1:
When dividing 6 by 30, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 30

Advancing to step 2:
68 divided by 30 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 60 from 68 leaves us with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 30

Let's proceed to step 3:
86 divided by 30 is 2 with a remainder of 26.
The next digit of our result is 2. 
Result so far: 22.0
The remainder is 26 after subtracting 60 from 86.
Grab the next digit (8) from the dividend, add it to 26, then carry on: 268 / 30

Advancing to step 4:
If we divide 268 by 30, we get 8 and a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 228.0
The remainder is 28 after subtracting 240 from 268.
Bring next digit (9) of the dividend behind the 28 and repeat the process: 289 / 30

Let's proceed to step 5:
30 can be fit into 289 9 times, resulting in a remainder of 19.
The next digit of our result is 9. 
Result so far: 2289.0
Deduct 270 from 289 and we're left with 19.
Grab the next digit (0) from the dividend, add it to 19, then carry on: 190 / 30

Moving on to step 6:
The number 30 fits into 190 6 times, leaving a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 22896.0
The remainder is 10 after subtracting 180 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
The number 30 fits into 100 3 times, leaving a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 22896.3
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
When dividing 100 by 30, we get 3 with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 22896.33
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 22896.33 with a remainder of 0.01.
