13073989 ÷ 680 
Our goal is to divide 13073989 by 680.

Advancing to step 1:
680 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 680

Going ahead to step 2:
When dividing 13 by 680, we get 0 with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 680

Advancing to step 3:
680 can be fit into 130 0 times, resulting in a remainder of 130.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 130 to get 130.
Include the next digit (7) from the dividend after 130, then repeat: 1307 / 680

Step 4:
The number 680 fits into 1307 1 times, leaving a remainder of 627.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 627 after subtracting 680 from 1307.
Grab the next digit (3) from the dividend, add it to 627, then carry on: 6273 / 680

On to step 5:
680 goes into 6273 9 times with a remainder of 153.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we take 6120 away from 6273, we end up with 153.
Append the next digit (9) from the dividend to 153 and continue with: 1539 / 680

Step 6:
If we divide 1539 by 680, we get 2 and a remainder of 179.
Use 2 as the next digit of our solution. 
Result so far: 192.0
Subtract 1360 from 1539 to get 179.
Append the next digit (8) from the dividend to 179 and continue with: 1798 / 680

Step 7:
680 can be fit into 1798 2 times, resulting in a remainder of 438.
Write down 2 as next digit of the result. 
Result so far: 1922.0
Subtracting 1360 from 1798 leaves us with 438.
Take the next digit (9) from the dividend and append it to 438, then repeat: 4389 / 680

Let's proceed to step 8:
4389 divided by 680 is 6 with a remainder of 309.
Use 6 as the next digit of our solution. 
Result so far: 19226.0
Subtracting 4080 from 4389 leaves us with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Going ahead to step 9:
3090 divided by 680 is 4 with a remainder of 370.
The next digit of our result is 4. 
Result so far: 19226.4
If we subtract 2720 from 3090, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Let's proceed to step 10:
680 can be fit into 3700 5 times, resulting in a remainder of 300.
The number 5 becomes the next digit in our result. 
Result so far: 19226.45
If we subtract 3400 from 3700, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 11:
680 can be fit into 3000 4 times, resulting in a remainder of 280.
Use 4 as the next digit of our solution. 
Result so far: 19226.454
Subtract 2720 from 3000 to get 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 12:
680 can be fit into 2800 4 times, resulting in a remainder of 80.
Use 4 as the next digit of our solution. 
Result so far: 19226.4544
Deduct 2720 from 2800 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final outcome is 19226.4544, with a leftover of 0.0008.
