We look at the division of 686989 by 3 
We're looking to find how many times 3 goes into 686989.

Advancing to step 1:
If we divide 6 by 3, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 0 after subtracting 6 from 6.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 3

Going ahead to step 2:
The number 3 fits into 8 2 times, leaving a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Deduct 6 from 8 and we're left with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 3

Moving on to step 3:
3 goes into 26 8 times with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 228.0
Subtracting 24 from 26 leaves us with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 3

Let's proceed to step 4:
When dividing 29 by 3, we get 9 with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 2289.0
Subtracting 27 from 29 leaves us with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 3

Moving on to step 5:
When dividing 28 by 3, we get 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 22899.0
Deduct 27 from 28 and we're left with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 3

Advancing to step 6:
When dividing 19 by 3, we get 6 with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 228996.0
Deduct 18 from 19 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 228996.3
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 8:
When dividing 10 by 3, we get 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 228996.33
Subtracting 9 from 10 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 228996.33 with a balance of 0.001.
