We look at the division of 687591 by 9 
Let's see how many times 9 fits into 687591.

Advancing to step 1:
If we divide 6 by 9, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 9

Step 2:
9 goes into 68 7 times with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 63 from 68 to get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 9

Let's proceed to step 3:
9 goes into 57 6 times with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 76.0
The remainder is 3 after subtracting 54 from 57.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 9

Moving on to step 4:
If we divide 35 by 9, we get 3 and a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 763.0
Deduct 27 from 35 and we're left with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 9

Step 5:
89 divided by 9 is 9 with a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 7639.0
Deduct 81 from 89 and we're left with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 9

Moving on to step 6:
The number 9 fits into 81 9 times, leaving a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 76399.0
Deduct 81 from 81 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.

Going ahead to step 7:
The number 9 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 76399.0
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.

Let's proceed to step 8:
0 divided by 9 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 76399.0
Subtract 0 from 0 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.

Our division results in 76399.0 with a remaining 0.0.
