We look at the division of 142172 by 72 
We're looking to find how many times 72 goes into 142172.

Going ahead to step 1:
72 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 72

Advancing to step 2:
When dividing 14 by 72, we get 0 with a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Append the next digit (2) from the dividend to 14 and continue with: 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
If we subtract 72 from 142, we get 70.
Bring next digit (1) of the dividend behind the 70 and repeat the process: 701 / 72

On to step 4:
When dividing 701 by 72, we get 9 with a remainder of 53.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtracting 648 from 701 leaves us with 53.
Include the next digit (7) from the dividend after 53, then repeat: 537 / 72

Going ahead to step 5:
When dividing 537 by 72, we get 7 with a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 197.0
Deduct 504 from 537 and we're left with 33.
Grab the next digit (2) from the dividend, add it to 33, then carry on: 332 / 72

On to step 6:
332 divided by 72 is 4 with a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 1974.0
Subtract 288 from 332 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 7:
72 can be fit into 440 6 times, resulting in a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 1974.6
If we subtract 432 from 440, we 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.

Step 8:
72 can be fit into 80 1 times, resulting in a remainder of 8.
The next digit of our result is 1. 
Result so far: 1974.61
If we take 72 away from 80, we end up 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.

Step 9:
80 divided by 72 is 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 1974.611
If we subtract 72 from 80, we 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.

The final outcome is 1974.611, with a leftover of 0.0008.
