680843 divided by 18 
Let's see how many times 18 fits into 680843.

On to step 1:
18 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 18

Advancing to step 2:
If we divide 68 by 18, we get 3 and a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 54 away from 68, we end up with 14.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 18

Step 3:
18 goes into 140 7 times with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Subtract 126 from 140 to get 14.
Include the next digit (8) from the dividend after 14, then repeat: 148 / 18

Advancing to step 4:
The number 18 fits into 148 8 times, leaving a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 378.0
The remainder is 4 after subtracting 144 from 148.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 18

On to step 5:
18 can be fit into 44 2 times, resulting in a remainder of 8.
The next digit of our result is 2. 
Result so far: 3782.0
If we take 36 away from 44, we end up with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 18

On to step 6:
When dividing 83 by 18, we get 4 with a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 37824.0
Deduct 72 from 83 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
The number 18 fits into 110 6 times, leaving a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 37824.6
Deduct 108 from 110 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
18 can be fit into 20 1 times, resulting in a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 37824.61
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
When dividing 20 by 18, we get 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 37824.611
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 37824.611, and the remainder is 0.0002.
