Let's divide 142950 by 72
We're looking to find how many times 72 goes into 142950.

Step 1:
If we divide 1 by 72, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 72

Going ahead to step 2:
72 goes into 14 0 times with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 72

Advancing to step 3:
142 divided by 72 is 1 with a remainder of 70.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 72 away from 142, we end up with 70.
Bring next digit (9) of the dividend behind the 70 and repeat the process: 709 / 72

Moving on to step 4:
72 goes into 709 9 times with a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtract 648 from 709 to get 61.
Grab the next digit (5) from the dividend, add it to 61, then carry on: 615 / 72

Moving on to step 5:
The number 72 fits into 615 8 times, leaving a remainder of 39.
The next digit of our result is 8. 
Result so far: 198.0
If we take 576 away from 615, we end up with 39.
Bring next digit (0) of the dividend behind the 39 and repeat the process: 390 / 72

Advancing to step 6:
When dividing 390 by 72, we get 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 1985.0
If we take 360 away from 390, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 7:
72 goes into 300 4 times with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 1985.4
If we subtract 288 from 300, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
If we divide 120 by 72, we get 1 and a remainder of 48.
The next digit of our result is 1. 
Result so far: 1985.41
If we take 72 away from 120, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 9:
72 goes into 480 6 times with a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 1985.416
Subtract 432 from 480 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 10:
The number 72 fits into 480 6 times, leaving a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 1985.4166
The remainder is 48 after subtracting 432 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 1985.4166, with a leftover of 0.00048.
