Let's divide 13666605 by 680
We want to divide 13666605 by 680.

Moving on to step 1:
The number 680 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 680

Going ahead to step 2:
The number 680 fits into 13 0 times, leaving a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Include the next digit (6) from the dividend after 13, then repeat: 136 / 680

Advancing to step 3:
The number 680 fits into 136 0 times, leaving a remainder of 136.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 136 leaves us with 136.
Bring next digit (6) of the dividend behind the 136 and repeat the process: 1366 / 680

Moving on to step 4:
680 can be fit into 1366 2 times, resulting in a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 6 after subtracting 1360 from 1366.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 680

Going ahead to step 5:
66 divided by 680 is 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we subtract 0 from 66, we get 66.
Grab the next digit (6) from the dividend, add it to 66, then carry on: 666 / 680

On to step 6:
The number 680 fits into 666 0 times, leaving a remainder of 666.
Write down 0 as next digit of the result. 
Result so far: 200.0
If we take 0 away from 666, we end up with 666.
Grab the next digit (0) from the dividend, add it to 666, then carry on: 6660 / 680

Advancing to step 7:
6660 divided by 680 is 9 with a remainder of 540.
Write down 9 as next digit of the result. 
Result so far: 2009.0
Subtracting 6120 from 6660 leaves us with 540.
Bring next digit (5) of the dividend behind the 540 and repeat the process: 5405 / 680

Advancing to step 8:
680 can be fit into 5405 7 times, resulting in a remainder of 645.
The next digit of our result is 7. 
Result so far: 20097.0
If we subtract 4760 from 5405, we get 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

Let's proceed to step 9:
680 can be fit into 6450 9 times, resulting in a remainder of 330.
The next digit of our result is 9. 
Result so far: 20097.9
The remainder is 330 after subtracting 6120 from 6450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 10:
680 goes into 3300 4 times with a remainder of 580.
Put 4 as the next digit of the answer. 
Result so far: 20097.94
Subtracting 2720 from 3300 leaves us with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

On to step 11:
When dividing 5800 by 680, we get 8 with a remainder of 360.
The number 8 becomes the next digit in our result. 
Result so far: 20097.948
The remainder is 360 after subtracting 5440 from 5800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 12:
When dividing 3600 by 680, we get 5 with a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 20097.9485
If we take 3400 away from 3600, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 13:
2000 divided by 680 is 2 with a remainder of 640.
The number 2 becomes the next digit in our result. 
Result so far: 20097.94852
The remainder is 640 after subtracting 1360 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

On to step 14:
680 goes into 6400 9 times with a remainder of 280.
Put 9 as the next digit of the answer. 
Result so far: 20097.948529
Deduct 6120 from 6400 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 15:
When dividing 2800 by 680, we get 4 with a remainder of 80.
Use 4 as the next digit of our solution. 
Result so far: 20097.9485294
If we subtract 2720 from 2800, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 16:
The number 680 fits into 800 1 times, leaving a remainder of 120.
Write down 1 as next digit of the result. 
Result so far: 20097.94852941
Deduct 680 from 800 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final outcome is 20097.94852941, with a leftover of 1.2e-07.
