We look at the division of 287463 by 72 
We want to divide 287463 by 72.

Step 1:
72 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 72

On to step 2:
28 divided by 72 is 0 with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Grab the next digit (7) from the dividend, add it to 28, then carry on: 287 / 72

Going ahead to step 3:
287 divided by 72 is 3 with a remainder of 71.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 216 from 287 and we're left with 71.
Take the next digit (4) from the dividend and append it to 71, then repeat: 714 / 72

Let's proceed to step 4:
714 divided by 72 is 9 with a remainder of 66.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
The remainder is 66 after subtracting 648 from 714.
Grab the next digit (6) from the dividend, add it to 66, then carry on: 666 / 72

Moving on to step 5:
When dividing 666 by 72, we get 9 with a remainder of 18.
The next digit of our result is 9. 
Result so far: 399.0
If we take 648 away from 666, we end up with 18.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 72

On to step 6:
72 can be fit into 183 2 times, resulting in a remainder of 39.
The next digit of our result is 2. 
Result so far: 3992.0
Subtract 144 from 183 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
The number 72 fits into 390 5 times, leaving a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 3992.5
The remainder is 30 after subtracting 360 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
72 can be fit into 300 4 times, resulting in a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 3992.54
Subtracting 288 from 300 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
The number 72 fits into 120 1 times, leaving a remainder of 48.
The next digit of our result is 1. 
Result so far: 3992.541
If we subtract 72 from 120, we 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.

Going ahead to step 10:
When dividing 480 by 72, we get 6 with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 3992.5416
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 11:
If we divide 480 by 72, we get 6 and a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 3992.54166
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.

The final outcome is 3992.54166, with a leftover of 4.8e-05.
