Let's divide 12442920 by 680
Our goal is to divide 12442920 by 680.

Advancing to step 1:
680 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 680

Going ahead to step 2:
680 can be fit into 12 0 times, resulting in a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 680

Step 3:
680 can be fit into 124 0 times, resulting in a remainder of 124.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 124, we end up with 124.
Fetch the next digit (4) from the dividend, attach it to 124 and continue: 1244 / 680

Going ahead to step 4:
If we divide 1244 by 680, we get 1 and a remainder of 564.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 564 after subtracting 680 from 1244.
Fetch the next digit (2) from the dividend, attach it to 564 and continue: 5642 / 680

Advancing to step 5:
When dividing 5642 by 680, we get 8 with a remainder of 202.
The next digit of our result is 8. 
Result so far: 18.0
Deduct 5440 from 5642 and we're left with 202.
Fetch the next digit (9) from the dividend, attach it to 202 and continue: 2029 / 680

Moving on to step 6:
2029 divided by 680 is 2 with a remainder of 669.
Write down 2 as next digit of the result. 
Result so far: 182.0
If we subtract 1360 from 2029, we get 669.
Grab the next digit (2) from the dividend, add it to 669, then carry on: 6692 / 680

Moving on to step 7:
680 can be fit into 6692 9 times, resulting in a remainder of 572.
Write down 9 as next digit of the result. 
Result so far: 1829.0
If we take 6120 away from 6692, we end up with 572.
Grab the next digit (0) from the dividend, add it to 572, then carry on: 5720 / 680

Step 8:
680 goes into 5720 8 times with a remainder of 280.
Record the quotient 8 as the next digit in the result. 
Result so far: 18298.0
Deduct 5440 from 5720 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.

Advancing to step 9:
The number 680 fits into 2800 4 times, leaving a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 18298.4
The remainder is 80 after subtracting 2720 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 10:
The number 680 fits into 800 1 times, leaving a remainder of 120.
Use 1 as the next digit of our solution. 
Result so far: 18298.41
If we take 680 away from 800, we end up 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.

Let's proceed to step 11:
1200 divided by 680 is 1 with a remainder of 520.
Use 1 as the next digit of our solution. 
Result so far: 18298.411
The remainder is 520 after subtracting 680 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Our division results in 18298.411 with a remaining 0.052.
