402301 ÷ 18 
We want to figure out the number of times 402301 can be divided by 18.

Going ahead to step 1:
The number 18 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 18

On to step 2:
40 divided by 18 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 36 from 40 leaves us with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 18

On to step 3:
The number 18 fits into 42 2 times, leaving a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 22.0
Deduct 36 from 42 and we're left with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 18

Moving on to step 4:
18 goes into 63 3 times with a remainder of 9.
The next digit of our result is 3. 
Result so far: 223.0
If we take 54 away from 63, we end up with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 18

Advancing to step 5:
18 can be fit into 90 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 2235.0
If we take 90 away from 90, we end up with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 18

Advancing to step 6:
If we divide 1 by 18, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 22350.0
Deduct 0 from 1 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
The number 18 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 22350.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
100 divided by 18 is 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 22350.05
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
100 divided by 18 is 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 22350.055
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 22350.055 with a remaining 0.001.
