126242 ÷ 18 
Let's see how many times 18 fits into 126242.

Let's proceed to step 1:
If we divide 1 by 18, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 18

On to step 2:
The number 18 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 18

Step 3:
The number 18 fits into 126 7 times, leaving a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 126 away from 126, we end up with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 18

Moving on to step 4:
18 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 70.0
Subtract 0 from 2 to get 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 18

Step 5:
If we divide 24 by 18, we get 1 and a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 701.0
If we subtract 18 from 24, we get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 18

Let's proceed to step 6:
18 goes into 62 3 times with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 7013.0
Subtracting 54 from 62 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
80 divided by 18 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 7013.4
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
18 goes into 80 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 7013.44
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 7013.44 with a remaining 0.008.
