We divide 686789 by 1
We're looking to find how many times 1 goes into 686789.

Moving on to step 1:
The number 1 fits into 6 6 times, leaving a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 0 after subtracting 6 from 6.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

Step 2:
When dividing 8 by 1, we get 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 68.0
If we subtract 8 from 8, we get 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 1

Advancing to step 3:
When dividing 6 by 1, we get 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 686.0
If we subtract 6 from 6, we get 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 1

On to step 4:
1 can be fit into 7 7 times, resulting in a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 6867.0
Subtract 7 from 7 to get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

Going ahead to step 5:
When dividing 8 by 1, we get 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 68678.0
Subtract 8 from 8 to get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 1

Going ahead to step 6:
The number 1 fits into 9 9 times, leaving a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 686789.0
If we subtract 9 from 9, we 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.

Let's proceed to step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 686789.0
If we subtract 0 from 0, we 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.

Step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 686789.0
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.

The final outcome is 686789.0, with a leftover of 0.0.
