11660021 ÷ 680 
Let's see how many times 680 fits into 11660021.

On to step 1:
1 divided by 680 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 680

Advancing to step 2:
If we divide 11 by 680, we get 0 and a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 11 leaves us with 11.
Bring next digit (6) of the dividend behind the 11 and repeat the process: 116 / 680

On to step 3:
680 can be fit into 116 0 times, resulting in a remainder of 116.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 116 to get 116.
Grab the next digit (6) from the dividend, add it to 116, then carry on: 1166 / 680

Advancing to step 4:
If we divide 1166 by 680, we get 1 and a remainder of 486.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 486 after subtracting 680 from 1166.
Append the next digit (0) from the dividend to 486 and continue with: 4860 / 680

Step 5:
680 can be fit into 4860 7 times, resulting in a remainder of 100.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtracting 4760 from 4860 leaves us with 100.
Grab the next digit (0) from the dividend, add it to 100, then carry on: 1000 / 680

Step 6:
If we divide 1000 by 680, we get 1 and a remainder of 320.
Record the quotient 1 as the next digit in the result. 
Result so far: 171.0
If we take 680 away from 1000, we end up with 320.
Include the next digit (2) from the dividend after 320, then repeat: 3202 / 680

On to step 7:
680 can be fit into 3202 4 times, resulting in a remainder of 482.
Record the quotient 4 as the next digit in the result. 
Result so far: 1714.0
The remainder is 482 after subtracting 2720 from 3202.
Take the next digit (1) from the dividend and append it to 482, then repeat: 4821 / 680

On to step 8:
When dividing 4821 by 680, we get 7 with a remainder of 61.
Put 7 as the next digit of the answer. 
Result so far: 17147.0
If we take 4760 away from 4821, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 9:
If we divide 610 by 680, we get 0 and a remainder of 610.
Use 0 as the next digit of our solution. 
Result so far: 17147.0
If we take 0 away from 610, we end up with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Going ahead to step 10:
The number 680 fits into 6100 8 times, leaving a remainder of 660.
Use 8 as the next digit of our solution. 
Result so far: 17147.08
If we take 5440 away from 6100, we end up with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Going ahead to step 11:
When dividing 6600 by 680, we get 9 with a remainder of 480.
The next digit of our result is 9. 
Result so far: 17147.089
If we subtract 6120 from 6600, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 12:
If we divide 4800 by 680, we get 7 and a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 17147.0897
The remainder is 40 after subtracting 4760 from 4800.
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 13:
680 goes into 400 0 times with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 17147.0897
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 14:
The number 680 fits into 4000 5 times, leaving a remainder of 600.
Record the quotient 5 as the next digit in the result. 
Result so far: 17147.089705
If we subtract 3400 from 4000, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 15:
680 can be fit into 6000 8 times, resulting in a remainder of 560.
Write down 8 as next digit of the result. 
Result so far: 17147.0897058
If we subtract 5440 from 6000, we 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.

Moving on to step 16:
When dividing 5600 by 680, we get 8 with a remainder of 160.
The number 8 becomes the next digit in our result. 
Result so far: 17147.08970588
Subtract 5440 from 5600 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The quotient of the division is 17147.08970588, and the remainder is 1.6e-07.
