We look at the division of 142242 by 72 
We're looking to find how many times 72 goes into 142242.

Step 1:
When dividing 1 by 72, we get 0 with 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.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 72

Going ahead to step 2:
If we divide 14 by 72, we get 0 and a remainder of 14.
Record the quotient 0 as the next digit in the result. 
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 / 72

Step 3:
When dividing 142 by 72, we get 1 with a remainder of 70.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 72 from 142 to get 70.
Append the next digit (2) from the dividend to 70 and continue with: 702 / 72

Going ahead to step 4:
72 can be fit into 702 9 times, resulting in a remainder of 54.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
The remainder is 54 after subtracting 648 from 702.
Grab the next digit (4) from the dividend, add it to 54, then carry on: 544 / 72

Let's proceed to step 5:
When dividing 544 by 72, we get 7 with a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 197.0
Subtract 504 from 544 to get 40.
Include the next digit (2) from the dividend after 40, then repeat: 402 / 72

Moving on to step 6:
The number 72 fits into 402 5 times, leaving a remainder of 42.
Use 5 as the next digit of our solution. 
Result so far: 1975.0
Subtracting 360 from 402 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 7:
The number 72 fits into 420 5 times, leaving a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 1975.5
Subtracting 360 from 420 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 8:
72 can be fit into 600 8 times, resulting in a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 1975.58
If we subtract 576 from 600, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
When dividing 240 by 72, we get 3 with a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 1975.583
Deduct 216 from 240 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
72 goes into 240 3 times with a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 1975.5833
If we take 216 away from 240, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 1975.5833 with a remainder of 0.00024.
