663185 divided by 72 
Our goal is to divide 663185 by 72.

Step 1:
If we divide 6 by 72, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 72

Moving on to step 2:
When dividing 66 by 72, we get 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Include the next digit (3) from the dividend after 66, then repeat: 663 / 72

Moving on to step 3:
663 divided by 72 is 9 with a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 15 after subtracting 648 from 663.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 72

On to step 4:
151 divided by 72 is 2 with a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 92.0
If we take 144 away from 151, we end up with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 72

On to step 5:
72 can be fit into 78 1 times, resulting in a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 921.0
Deduct 72 from 78 and we're left with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 72

Advancing to step 6:
65 divided by 72 is 0 with a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 9210.0
Subtracting 0 from 65 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 7:
The number 72 fits into 650 9 times, leaving a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 9210.9
If we subtract 648 from 650, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
If we divide 20 by 72, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 9210.9
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
When dividing 200 by 72, we get 2 with a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 9210.902
If we take 144 away from 200, we end up 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.

Let's proceed to step 10:
If we divide 560 by 72, we get 7 and a remainder of 56.
The next digit of our result is 7. 
Result so far: 9210.9027
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.

Step 11:
If we divide 560 by 72, we get 7 and a remainder of 56.
Write down 7 as next digit of the result. 
Result so far: 9210.90277
The remainder is 56 after subtracting 504 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final outcome is 9210.90277, with a leftover of 5.6e-05.
