We're dividing 378680 by 18 
We want to figure out the number of times 378680 can be divided by 18.

Advancing to step 1:
18 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 18

Advancing to step 2:
18 goes into 37 2 times with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 36 from 37 to get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 18

On to step 3:
The number 18 fits into 18 1 times, leaving a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Deduct 18 from 18 and we're left with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 18

Step 4:
If we divide 6 by 18, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 210.0
Subtract 0 from 6 to get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 18

Advancing to step 5:
If we divide 68 by 18, we get 3 and a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 2103.0
Subtract 54 from 68 to get 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 18

Going ahead to step 6:
The number 18 fits into 140 7 times, leaving a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 21037.0
The remainder is 14 after subtracting 126 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
140 divided by 18 is 7 with a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 21037.7
The remainder is 14 after subtracting 126 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
The number 18 fits into 140 7 times, leaving a remainder of 14.
The next digit of our result is 7. 
Result so far: 21037.77
Subtracting 126 from 140 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 21037.77 with a remaining 0.014.
