We look at the division of 66830913 by 685 
We want to figure out the number of times 66830913 can be divided by 685.

Let's proceed to step 1:
6 divided by 685 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 685

Step 2:
685 can be fit into 66 0 times, resulting in a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Fetch the next digit (8) from the dividend, attach it to 66 and continue: 668 / 685

Moving on to step 3:
When dividing 668 by 685, we get 0 with a remainder of 668.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 668 leaves us with 668.
Fetch the next digit (3) from the dividend, attach it to 668 and continue: 6683 / 685

On to step 4:
When dividing 6683 by 685, we get 9 with a remainder of 518.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 6165 from 6683 and we're left with 518.
Bring next digit (0) of the dividend behind the 518 and repeat the process: 5180 / 685

Going ahead to step 5:
The number 685 fits into 5180 7 times, leaving a remainder of 385.
Write down 7 as next digit of the result. 
Result so far: 97.0
Subtracting 4795 from 5180 leaves us with 385.
Grab the next digit (9) from the dividend, add it to 385, then carry on: 3859 / 685

Moving on to step 6:
The number 685 fits into 3859 5 times, leaving a remainder of 434.
The next digit of our result is 5. 
Result so far: 975.0
Deduct 3425 from 3859 and we're left with 434.
Grab the next digit (1) from the dividend, add it to 434, then carry on: 4341 / 685

Going ahead to step 7:
When dividing 4341 by 685, we get 6 with a remainder of 231.
Write down 6 as next digit of the result. 
Result so far: 9756.0
The remainder is 231 after subtracting 4110 from 4341.
Bring next digit (3) of the dividend behind the 231 and repeat the process: 2313 / 685

Going ahead to step 8:
685 goes into 2313 3 times with a remainder of 258.
Put 3 as the next digit of the answer. 
Result so far: 97563.0
Subtracting 2055 from 2313 leaves us with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

On to step 9:
The number 685 fits into 2580 3 times, leaving a remainder of 525.
Write down 3 as next digit of the result. 
Result so far: 97563.3
If we subtract 2055 from 2580, we get 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Moving on to step 10:
5250 divided by 685 is 7 with a remainder of 455.
Record the quotient 7 as the next digit in the result. 
Result so far: 97563.37
The remainder is 455 after subtracting 4795 from 5250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Moving on to step 11:
If we divide 4550 by 685, we get 6 and a remainder of 440.
The next digit of our result is 6. 
Result so far: 97563.376
The remainder is 440 after subtracting 4110 from 4550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 12:
If we divide 4400 by 685, we get 6 and a remainder of 290.
Record the quotient 6 as the next digit in the result. 
Result so far: 97563.3766
If we take 4110 away from 4400, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

In conclusion, the division gives 97563.3766 with a balance of 0.0029.
