Let's divide 143493 by 72
Our goal is to divide 143493 by 72.

Moving on to step 1:
72 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 72

On 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
If we subtract 0 from 14, we get 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 72

Advancing to step 3:
72 can be fit into 143 1 times, resulting in a remainder of 71.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 72 from 143 to get 71.
Bring next digit (4) of the dividend behind the 71 and repeat the process: 714 / 72

Going ahead to step 4:
When dividing 714 by 72, we get 9 with a remainder of 66.
The next digit of our result is 9. 
Result so far: 19.0
The remainder is 66 after subtracting 648 from 714.
Include the next digit (9) from the dividend after 66, then repeat: 669 / 72

Going ahead to step 5:
If we divide 669 by 72, we get 9 and a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 199.0
Subtracting 648 from 669 leaves us with 21.
Take the next digit (3) from the dividend and append it to 21, then repeat: 213 / 72

Step 6:
213 divided by 72 is 2 with a remainder of 69.
The number 2 becomes the next digit in our result. 
Result so far: 1992.0
Deduct 144 from 213 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 7:
If we divide 690 by 72, we get 9 and a remainder of 42.
Put 9 as the next digit of the answer. 
Result so far: 1992.9
If we subtract 648 from 690, we get 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 8:
If we divide 420 by 72, we get 5 and a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 1992.95
If we take 360 away from 420, we end up 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.

Step 9:
If we divide 600 by 72, we get 8 and a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 1992.958
If we take 576 away from 600, 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.

Step 10:
240 divided by 72 is 3 with a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 1992.9583
Subtracting 216 from 240 leaves us 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.

On to step 11:
When dividing 240 by 72, we get 3 with a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 1992.95833
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.

After the division, we end up with 1992.95833 and a remainder of 2.4e-05.
