We're dividing 375402 by 18 
We want to figure out the number of times 375402 can be divided by 18.

Going ahead to step 1:
If we divide 3 by 18, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 18

Moving on to step 2:
37 divided by 18 is 2 with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 36 from 37, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 18

Let's proceed to step 3:
18 can be fit into 15 0 times, resulting in a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Deduct 0 from 15 and we're left with 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 18

On to step 4:
18 goes into 154 8 times with a remainder of 10.
The next digit of our result is 8. 
Result so far: 208.0
If we take 144 away from 154, we end up with 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 18

On to step 5:
100 divided by 18 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 2085.0
Deduct 90 from 100 and we're left with 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 18

Let's proceed to step 6:
If we divide 102 by 18, we get 5 and a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 20855.0
If we take 90 away from 102, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
18 can be fit into 120 6 times, resulting in a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 20855.6
Subtracting 108 from 120 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
The number 18 fits into 120 6 times, leaving a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 20855.66
Deduct 108 from 120 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 20855.66 with a remaining 0.012.
