We look at the division of 688473 by 9 
We want to figure out the number of times 688473 can be divided by 9.

Step 1:
If we divide 6 by 9, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 9

Going ahead to step 2:
9 can be fit into 68 7 times, resulting in a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 63 from 68 and we're left with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 9

On to step 3:
If we divide 58 by 9, we get 6 and a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
Subtract 54 from 58 to get 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 9

Let's proceed to step 4:
44 divided by 9 is 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 764.0
Subtracting 36 from 44 leaves us with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 9

Going ahead to step 5:
When dividing 87 by 9, we get 9 with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 7649.0
Deduct 81 from 87 and we're left with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 9

Let's proceed to step 6:
If we divide 63 by 9, we get 7 and a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 76497.0
Deduct 63 from 63 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.

Moving on to step 7:
0 divided by 9 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 76497.0
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.

Moving on to step 8:
0 divided by 9 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 76497.0
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.

The final outcome is 76497.0, with a leftover of 0.0.
