Let's divide 66940795 by 688
We want to figure out the number of times 66940795 can be divided by 688.

Advancing to step 1:
688 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 688

Advancing to step 2:
If we divide 66 by 688, we get 0 and a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Take the next digit (9) from the dividend and append it to 66, then repeat: 669 / 688

Step 3:
If we divide 669 by 688, we get 0 and a remainder of 669.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 669, we get 669.
Grab the next digit (4) from the dividend, add it to 669, then carry on: 6694 / 688

Moving on to step 4:
The number 688 fits into 6694 9 times, leaving a remainder of 502.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 6192 from 6694 and we're left with 502.
Bring next digit (0) of the dividend behind the 502 and repeat the process: 5020 / 688

Let's proceed to step 5:
688 can be fit into 5020 7 times, resulting in a remainder of 204.
Write down 7 as next digit of the result. 
Result so far: 97.0
The remainder is 204 after subtracting 4816 from 5020.
Append the next digit (7) from the dividend to 204 and continue with: 2047 / 688

Advancing to step 6:
2047 divided by 688 is 2 with a remainder of 671.
Record the quotient 2 as the next digit in the result. 
Result so far: 972.0
If we subtract 1376 from 2047, we get 671.
Grab the next digit (9) from the dividend, add it to 671, then carry on: 6719 / 688

Moving on to step 7:
688 goes into 6719 9 times with a remainder of 527.
Record the quotient 9 as the next digit in the result. 
Result so far: 9729.0
Subtracting 6192 from 6719 leaves us with 527.
Fetch the next digit (5) from the dividend, attach it to 527 and continue: 5275 / 688

Moving on to step 8:
The number 688 fits into 5275 7 times, leaving a remainder of 459.
Put 7 as the next digit of the answer. 
Result so far: 97297.0
If we take 4816 away from 5275, we end up with 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Going ahead to step 9:
4590 divided by 688 is 6 with a remainder of 462.
The next digit of our result is 6. 
Result so far: 97297.6
The remainder is 462 after subtracting 4128 from 4590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Step 10:
The number 688 fits into 4620 6 times, leaving a remainder of 492.
The number 6 becomes the next digit in our result. 
Result so far: 97297.66
Subtracting 4128 from 4620 leaves us with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

The final result is 97297.66 with a remainder of 0.492.
