686910 divided by 10 
We want to figure out the number of times 686910 can be divided by 10.

Advancing to step 1:
If we divide 6 by 10, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 10

Step 2:
10 goes into 68 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 60 away from 68, we end up with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 10

Let's proceed to step 3:
86 divided by 10 is 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 68.0
Subtracting 80 from 86 leaves us with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 10

Advancing to step 4:
10 goes into 69 6 times with a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 686.0
If we take 60 away from 69, we end up with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 10

Moving on to step 5:
91 divided by 10 is 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 6869.0
Subtract 90 from 91 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 10

Going ahead to step 6:
If we divide 10 by 10, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 68691.0
Subtract 10 from 10 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 68691.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
10 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 68691.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 68691.0 with a remainder of 0.0.
