142105 ÷ 18 
Our goal is to divide 142105 by 18.

Moving on to step 1:
1 divided by 18 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 18

Step 2:
18 can be fit into 14 0 times, resulting in a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Fetch the next digit (2) from the dividend, attach it to 14 and continue: 142 / 18

Step 3:
18 can be fit into 142 7 times, resulting in a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 16 after subtracting 126 from 142.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 18

Advancing to step 4:
The number 18 fits into 161 8 times, leaving a remainder of 17.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
Deduct 144 from 161 and we're left with 17.
Take the next digit (0) from the dividend and append it to 17, then repeat: 170 / 18

Moving on to step 5:
170 divided by 18 is 9 with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 789.0
Deduct 162 from 170 and we're left with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 18

Going ahead to step 6:
85 divided by 18 is 4 with a remainder of 13.
The number 4 becomes the next digit in our result. 
Result so far: 7894.0
If we subtract 72 from 85, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
18 can be fit into 130 7 times, resulting in a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 7894.7
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
18 can be fit into 40 2 times, resulting in a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 7894.72
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
18 can be fit into 40 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 7894.722
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 7894.722 with a remaining 0.0004.
