663433 ÷ 72 
We want to figure out the number of times 663433 can be divided by 72.

On to step 1:
72 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 72

Moving on to step 2:
72 can be fit into 66 0 times, resulting in a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Grab the next digit (3) from the dividend, add it to 66, then carry on: 663 / 72

Moving on to step 3:
72 can be fit into 663 9 times, resulting in a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 648 away from 663, we end up with 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 72

Moving on to step 4:
If we divide 154 by 72, we get 2 and a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 92.0
Subtract 144 from 154 to get 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 72

Let's proceed to step 5:
When dividing 103 by 72, we get 1 with a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 921.0
The remainder is 31 after subtracting 72 from 103.
Take the next digit (3) from the dividend and append it to 31, then repeat: 313 / 72

On to step 6:
313 divided by 72 is 4 with a remainder of 25.
The number 4 becomes the next digit in our result. 
Result so far: 9214.0
Subtract 288 from 313 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 7:
72 can be fit into 250 3 times, resulting in a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 9214.3
Subtracting 216 from 250 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
72 can be fit into 340 4 times, resulting in a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 9214.34
If we take 288 away from 340, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 9:
72 goes into 520 7 times with a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 9214.347
The remainder is 16 after subtracting 504 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
If we divide 160 by 72, we get 2 and a remainder of 16.
The next digit of our result is 2. 
Result so far: 9214.3472
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
If we divide 160 by 72, we get 2 and a remainder of 16.
The next digit of our result is 2. 
Result so far: 9214.34722
If we take 144 away from 160, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 9214.34722, and the remainder is 1.6e-05.
