Let's divide 66797550 by 680
Let's see how many times 680 fits into 66797550.

Going ahead to step 1:
When dividing 6 by 680, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 680

Advancing to step 2:
If we divide 66 by 680, we get 0 and a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Bring next digit (7) of the dividend behind the 66 and repeat the process: 667 / 680

Let's proceed to step 3:
When dividing 667 by 680, we get 0 with a remainder of 667.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 667, we end up with 667.
Fetch the next digit (9) from the dividend, attach it to 667 and continue: 6679 / 680

Going ahead to step 4:
680 can be fit into 6679 9 times, resulting in a remainder of 559.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 6120 from 6679 leaves us with 559.
Fetch the next digit (7) from the dividend, attach it to 559 and continue: 5597 / 680

Let's proceed to step 5:
5597 divided by 680 is 8 with a remainder of 157.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
If we take 5440 away from 5597, we end up with 157.
Take the next digit (5) from the dividend and append it to 157, then repeat: 1575 / 680

Let's proceed to step 6:
680 goes into 1575 2 times with a remainder of 215.
Record the quotient 2 as the next digit in the result. 
Result so far: 982.0
The remainder is 215 after subtracting 1360 from 1575.
Append the next digit (5) from the dividend to 215 and continue with: 2155 / 680

Going ahead to step 7:
If we divide 2155 by 680, we get 3 and a remainder of 115.
The number 3 becomes the next digit in our result. 
Result so far: 9823.0
Deduct 2040 from 2155 and we're left with 115.
Bring next digit (0) of the dividend behind the 115 and repeat the process: 1150 / 680

Moving on to step 8:
680 goes into 1150 1 times with a remainder of 470.
Use 1 as the next digit of our solution. 
Result so far: 98231.0
If we take 680 away from 1150, we end up with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

On to step 9:
The number 680 fits into 4700 6 times, leaving a remainder of 620.
Use 6 as the next digit of our solution. 
Result so far: 98231.6
Deduct 4080 from 4700 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Advancing to step 10:
If we divide 6200 by 680, we get 9 and a remainder of 80.
Use 9 as the next digit of our solution. 
Result so far: 98231.69
Subtracting 6120 from 6200 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 11:
680 goes into 800 1 times with a remainder of 120.
Put 1 as the next digit of the answer. 
Result so far: 98231.691
If we subtract 680 from 800, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 12:
The number 680 fits into 1200 1 times, leaving a remainder of 520.
Put 1 as the next digit of the answer. 
Result so far: 98231.6911
The remainder is 520 after subtracting 680 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

The final result is 98231.6911 with a remainder of 0.0052.
