142252 ÷ 40 
Our goal is to divide 142252 by 40.

Going ahead to step 1:
If we divide 1 by 40, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 40

Advancing to step 2:
The number 40 fits into 14 0 times, leaving a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 40

Moving on to step 3:
The number 40 fits into 142 3 times, leaving a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 120 from 142 leaves us with 22.
Take the next digit (2) from the dividend and append it to 22, then repeat: 222 / 40

Moving on to step 4:
When dividing 222 by 40, we get 5 with a remainder of 22.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Deduct 200 from 222 and we're left with 22.
Grab the next digit (5) from the dividend, add it to 22, then carry on: 225 / 40

Advancing to step 5:
When dividing 225 by 40, we get 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 355.0
If we subtract 200 from 225, we get 25.
Include the next digit (2) from the dividend after 25, then repeat: 252 / 40

Step 6:
If we divide 252 by 40, we get 6 and a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 3556.0
The remainder is 12 after subtracting 240 from 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
40 goes into 120 3 times with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3556.3
Deduct 120 from 120 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
When dividing 0 by 40, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3556.3
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
When dividing 0 by 40, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3556.3
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 3556.3, with a leftover of 0.0.
