863984 divided by 72 
We're looking to find how many times 72 goes into 863984.

Let's proceed to step 1:
72 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 72

Step 2:
86 divided by 72 is 1 with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 72 away from 86, we end up with 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 72

Advancing to step 3:
143 divided by 72 is 1 with a remainder of 71.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 71 after subtracting 72 from 143.
Include the next digit (9) from the dividend after 71, then repeat: 719 / 72

On to step 4:
If we divide 719 by 72, we get 9 and a remainder of 71.
Record the quotient 9 as the next digit in the result. 
Result so far: 119.0
Subtract 648 from 719 to get 71.
Bring next digit (8) of the dividend behind the 71 and repeat the process: 718 / 72

Moving on to step 5:
72 can be fit into 718 9 times, resulting in a remainder of 70.
Use 9 as the next digit of our solution. 
Result so far: 1199.0
If we subtract 648 from 718, we get 70.
Grab the next digit (4) from the dividend, add it to 70, then carry on: 704 / 72

Moving on to step 6:
72 can be fit into 704 9 times, resulting in a remainder of 56.
Put 9 as the next digit of the answer. 
Result so far: 11999.0
The remainder is 56 after subtracting 648 from 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 7:
72 can be fit into 560 7 times, resulting in a remainder of 56.
Write down 7 as next digit of the result. 
Result so far: 11999.7
Subtracting 504 from 560 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 8:
72 can be fit into 560 7 times, resulting in a remainder of 56.
Put 7 as the next digit of the answer. 
Result so far: 11999.77
Subtracting 504 from 560 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The quotient of the division is 11999.77, and the remainder is 0.056.
