We look at the division of 66475475 by 688 
Let's see how many times 688 fits into 66475475.

Advancing to step 1:
If we divide 6 by 688, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 688

Advancing to step 2:
688 goes into 66 0 times with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Take the next digit (4) from the dividend and append it to 66, then repeat: 664 / 688

On to step 3:
664 divided by 688 is 0 with a remainder of 664.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 664 to get 664.
Take the next digit (7) from the dividend and append it to 664, then repeat: 6647 / 688

Moving on to step 4:
If we divide 6647 by 688, we get 9 and a remainder of 455.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 6192 away from 6647, we end up with 455.
Bring next digit (5) of the dividend behind the 455 and repeat the process: 4555 / 688

Let's proceed to step 5:
The number 688 fits into 4555 6 times, leaving a remainder of 427.
Use 6 as the next digit of our solution. 
Result so far: 96.0
The remainder is 427 after subtracting 4128 from 4555.
Take the next digit (4) from the dividend and append it to 427, then repeat: 4274 / 688

Step 6:
688 goes into 4274 6 times with a remainder of 146.
The next digit of our result is 6. 
Result so far: 966.0
Subtracting 4128 from 4274 leaves us with 146.
Append the next digit (7) from the dividend to 146 and continue with: 1467 / 688

Moving on to step 7:
If we divide 1467 by 688, we get 2 and a remainder of 91.
The next digit of our result is 2. 
Result so far: 9662.0
Subtract 1376 from 1467 to get 91.
Bring next digit (5) of the dividend behind the 91 and repeat the process: 915 / 688

Let's proceed to step 8:
The number 688 fits into 915 1 times, leaving a remainder of 227.
The number 1 becomes the next digit in our result. 
Result so far: 96621.0
The remainder is 227 after subtracting 688 from 915.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

On to step 9:
688 can be fit into 2270 3 times, resulting in a remainder of 206.
Record the quotient 3 as the next digit in the result. 
Result so far: 96621.3
If we subtract 2064 from 2270, we get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

On to step 10:
688 goes into 2060 2 times with a remainder of 684.
Put 2 as the next digit of the answer. 
Result so far: 96621.32
Subtracting 1376 from 2060 leaves us with 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Step 11:
When dividing 6840 by 688, we get 9 with a remainder of 648.
Write down 9 as next digit of the result. 
Result so far: 96621.329
If we take 6192 away from 6840, we end up with 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Advancing to step 12:
When dividing 6480 by 688, we get 9 with a remainder of 288.
Write down 9 as next digit of the result. 
Result so far: 96621.3299
Subtract 6192 from 6480 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The final outcome is 96621.3299, with a leftover of 0.00288.
