680456 ÷ 13 
We want to divide 680456 by 13.

On to step 1:
When dividing 6 by 13, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 13

On to step 2:
13 can be fit into 68 5 times, resulting in a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 65 from 68 to get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 13

Let's proceed to step 3:
13 goes into 30 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
If we take 26 away from 30, we end up with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 13

Going ahead to step 4:
When dividing 44 by 13, we get 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 523.0
If we take 39 away from 44, we end up with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 13

Moving on to step 5:
13 goes into 55 4 times with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 5234.0
If we subtract 52 from 55, we get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 13

Going ahead to step 6:
If we divide 36 by 13, we get 2 and a remainder of 10.
The next digit of our result is 2. 
Result so far: 52342.0
If we take 26 away from 36, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
13 can be fit into 100 7 times, resulting in a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 52342.7
If we take 91 away from 100, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 8:
90 divided by 13 is 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 52342.76
The remainder is 12 after subtracting 78 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
120 divided by 13 is 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 52342.769
Subtract 117 from 120 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 10:
13 can be fit into 30 2 times, resulting in a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 52342.7692
Subtract 26 from 30 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
When dividing 40 by 13, we get 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 52342.76923
Subtracting 39 from 40 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 12:
13 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 52342.76923
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 13:
The number 13 fits into 100 7 times, leaving a remainder of 9.
The next digit of our result is 7. 
Result so far: 52342.7692307
Subtracting 91 from 100 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 14:
13 can be fit into 90 6 times, resulting in a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 52342.76923076
The remainder is 12 after subtracting 78 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 52342.76923076, with a leftover of 1.2e-08.
