We're dividing 663369 by 72 
We want to divide 663369 by 72.

Step 1:
When dividing 6 by 72, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 72

Going ahead to step 2:
The number 72 fits into 66 0 times, leaving a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Include the next digit (3) from the dividend after 66, then repeat: 663 / 72

On to step 3:
If we divide 663 by 72, we get 9 and a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 648 from 663 and we're left with 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 72

On to step 4:
72 can be fit into 153 2 times, resulting in a remainder of 9.
The next digit of our result is 2. 
Result so far: 92.0
Subtract 144 from 153 to get 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 72

Step 5:
When dividing 96 by 72, we get 1 with a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 921.0
Deduct 72 from 96 and we're left with 24.
Bring next digit (9) of the dividend behind the 24 and repeat the process: 249 / 72

On to step 6:
249 divided by 72 is 3 with a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 9213.0
If we take 216 away from 249, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 7:
The number 72 fits into 330 4 times, leaving a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 9213.4
Subtract 288 from 330 to 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.

Moving on to step 8:
The number 72 fits into 420 5 times, leaving a remainder of 60.
The next digit of our result is 5. 
Result so far: 9213.45
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.

Advancing to step 9:
72 can be fit into 600 8 times, resulting in a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 9213.458
Subtract 576 from 600 to get 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:
72 can be fit into 240 3 times, resulting in a remainder of 24.
The next digit of our result is 3. 
Result so far: 9213.4583
Subtract 216 from 240 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 11:
240 divided by 72 is 3 with a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 9213.45833
The remainder is 24 after subtracting 216 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 9213.45833, and the remainder is 2.4e-05.
