18437791 ÷ 680 
Our goal is to divide 18437791 by 680.

Moving on to step 1:
If we divide 1 by 680, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 680

Going ahead to step 2:
If we divide 18 by 680, we get 0 and a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Bring next digit (4) of the dividend behind the 18 and repeat the process: 184 / 680

Moving on to step 3:
If we divide 184 by 680, we get 0 and a remainder of 184.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 184 after subtracting 0 from 184.
Bring next digit (3) of the dividend behind the 184 and repeat the process: 1843 / 680

Going ahead to step 4:
If we divide 1843 by 680, we get 2 and a remainder of 483.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 1360 from 1843 leaves us with 483.
Append the next digit (7) from the dividend to 483 and continue with: 4837 / 680

Step 5:
When dividing 4837 by 680, we get 7 with a remainder of 77.
Write down 7 as next digit of the result. 
Result so far: 27.0
Subtracting 4760 from 4837 leaves us with 77.
Include the next digit (7) from the dividend after 77, then repeat: 777 / 680

Going ahead to step 6:
If we divide 777 by 680, we get 1 and a remainder of 97.
Record the quotient 1 as the next digit in the result. 
Result so far: 271.0
Subtracting 680 from 777 leaves us with 97.
Bring next digit (9) of the dividend behind the 97 and repeat the process: 979 / 680

Moving on to step 7:
680 can be fit into 979 1 times, resulting in a remainder of 299.
The number 1 becomes the next digit in our result. 
Result so far: 2711.0
The remainder is 299 after subtracting 680 from 979.
Grab the next digit (1) from the dividend, add it to 299, then carry on: 2991 / 680

On to step 8:
2991 divided by 680 is 4 with a remainder of 271.
The next digit of our result is 4. 
Result so far: 27114.0
Subtract 2720 from 2991 to get 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Advancing to step 9:
680 goes into 2710 3 times with a remainder of 670.
The number 3 becomes the next digit in our result. 
Result so far: 27114.3
If we subtract 2040 from 2710, we get 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Let's proceed to step 10:
6700 divided by 680 is 9 with a remainder of 580.
Use 9 as the next digit of our solution. 
Result so far: 27114.39
The remainder is 580 after subtracting 6120 from 6700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Step 11:
The number 680 fits into 5800 8 times, leaving a remainder of 360.
The next digit of our result is 8. 
Result so far: 27114.398
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.

Moving on to step 12:
The number 680 fits into 3600 5 times, leaving a remainder of 200.
Write down 5 as next digit of the result. 
Result so far: 27114.3985
Subtract 3400 from 3600 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 13:
680 goes into 2000 2 times with a remainder of 640.
The next digit of our result is 2. 
Result so far: 27114.39852
Subtract 1360 from 2000 to get 640.
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:
When dividing 6400 by 680, we get 9 with a remainder of 280.
Put 9 as the next digit of the answer. 
Result so far: 27114.398529
The remainder is 280 after subtracting 6120 from 6400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 15:
680 goes into 2800 4 times with a remainder of 80.
Put 4 as the next digit of the answer. 
Result so far: 27114.3985294
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:
680 goes into 800 1 times with a remainder of 120.
Put 1 as the next digit of the answer. 
Result so far: 27114.39852941
If we subtract 680 from 800, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

After the division, we end up with 27114.39852941 and a remainder of 1.2e-07.
