Let's divide 686609 by 1
We're looking to find how many times 1 goes into 686609.

Moving on to step 1:
When dividing 6 by 1, we get 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 6 away from 6, we end up with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 1

Let's proceed to step 2:
1 can be fit into 8 8 times, resulting in a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
Deduct 8 from 8 and we're left with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 1

Advancing to step 3:
1 can be fit into 6 6 times, resulting in a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 686.0
If we subtract 6 from 6, we get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 1

Let's proceed to step 4:
If we divide 6 by 1, we get 6 and a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 6866.0
The remainder is 0 after subtracting 6 from 6.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

On to step 5:
0 divided by 1 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 68660.0
If we subtract 0 from 0, we get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 1

Going ahead to step 6:
When dividing 9 by 1, we get 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 686609.0
If we take 9 away from 9, 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.

Moving on to step 7:
1 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 686609.0
Deduct 0 from 0 and we're left 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:
0 divided by 1 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 686609.0
Deduct 0 from 0 and we're left 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.

Our division results in 686609.0 with a remaining 0.0.
