Let's divide 18238639 by 142
Our goal is to divide 18238639 by 142.

Moving on to step 1:
When dividing 1 by 142, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 142

Going ahead to step 2:
142 goes into 18 0 times with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Append the next digit (2) from the dividend to 18 and continue with: 182 / 142

Going ahead to step 3:
The number 142 fits into 182 1 times, leaving a remainder of 40.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 40 after subtracting 142 from 182.
Grab the next digit (3) from the dividend, add it to 40, then carry on: 403 / 142

On to step 4:
If we divide 403 by 142, we get 2 and a remainder of 119.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 119 after subtracting 284 from 403.
Include the next digit (8) from the dividend after 119, then repeat: 1198 / 142

Let's proceed to step 5:
When dividing 1198 by 142, we get 8 with a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
Subtracting 1136 from 1198 leaves us with 62.
Bring next digit (6) of the dividend behind the 62 and repeat the process: 626 / 142

Step 6:
If we divide 626 by 142, we get 4 and a remainder of 58.
The number 4 becomes the next digit in our result. 
Result so far: 1284.0
Deduct 568 from 626 and we're left with 58.
Append the next digit (3) from the dividend to 58 and continue with: 583 / 142

Going ahead to step 7:
583 divided by 142 is 4 with a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 12844.0
The remainder is 15 after subtracting 568 from 583.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 142

Going ahead to step 8:
142 can be fit into 159 1 times, resulting in a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 128441.0
If we subtract 142 from 159, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 9:
142 can be fit into 170 1 times, resulting in a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 128441.1
Subtract 142 from 170 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 10:
If we divide 280 by 142, we get 1 and a remainder of 138.
Write down 1 as next digit of the result. 
Result so far: 128441.11
Deduct 142 from 280 and we're left with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

The final result is 128441.11 with a remainder of 0.138.
