68405550 divided by 680 
We want to figure out the number of times 68405550 can be divided by 680.

Going ahead to step 1:
When dividing 6 by 680, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 680

Advancing to step 2:
68 divided by 680 is 0 with a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Include the next digit (4) from the dividend after 68, then repeat: 684 / 680

On to step 3:
The number 680 fits into 684 1 times, leaving a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 680 from 684 to get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 680

Let's proceed to step 4:
680 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 40 after subtracting 0 from 40.
Grab the next digit (5) from the dividend, add it to 40, then carry on: 405 / 680

Moving on to step 5:
680 can be fit into 405 0 times, resulting in a remainder of 405.
Put 0 as the next digit of the answer. 
Result so far: 100.0
If we subtract 0 from 405, we get 405.
Include the next digit (5) from the dividend after 405, then repeat: 4055 / 680

On to step 6:
680 can be fit into 4055 5 times, resulting in a remainder of 655.
Put 5 as the next digit of the answer. 
Result so far: 1005.0
The remainder is 655 after subtracting 3400 from 4055.
Include the next digit (5) from the dividend after 655, then repeat: 6555 / 680

Going ahead to step 7:
680 goes into 6555 9 times with a remainder of 435.
Record the quotient 9 as the next digit in the result. 
Result so far: 10059.0
If we subtract 6120 from 6555, we get 435.
Take the next digit (0) from the dividend and append it to 435, then repeat: 4350 / 680

Step 8:
If we divide 4350 by 680, we get 6 and a remainder of 270.
The number 6 becomes the next digit in our result. 
Result so far: 100596.0
Subtracting 4080 from 4350 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 9:
680 can be fit into 2700 3 times, resulting in a remainder of 660.
Record the quotient 3 as the next digit in the result. 
Result so far: 100596.3
If we subtract 2040 from 2700, we get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Advancing to step 10:
The number 680 fits into 6600 9 times, leaving a remainder of 480.
The next digit of our result is 9. 
Result so far: 100596.39
Deduct 6120 from 6600 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 11:
4800 divided by 680 is 7 with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 100596.397
Subtracting 4760 from 4800 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 12:
400 divided by 680 is 0 with a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 100596.397
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 13:
The number 680 fits into 4000 5 times, leaving a remainder of 600.
Write down 5 as next digit of the result. 
Result so far: 100596.39705
Subtracting 3400 from 4000 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 14:
680 goes into 6000 8 times with a remainder of 560.
The number 8 becomes the next digit in our result. 
Result so far: 100596.397058
Subtract 5440 from 6000 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 15:
680 can be fit into 5600 8 times, resulting in a remainder of 160.
Write down 8 as next digit of the result. 
Result so far: 100596.3970588
Subtracting 5440 from 5600 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

After the division, we end up with 100596.3970588 and a remainder of 1.6e-06.
