686647 ÷ 72 
We want to figure out the number of times 686647 can be divided by 72.

Moving on to step 1:
The number 72 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 72

Let's proceed to step 2:
72 goes into 68 0 times with a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Take the next digit (6) from the dividend and append it to 68, then repeat: 686 / 72

Step 3:
The number 72 fits into 686 9 times, leaving a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 648 from 686 and we're left with 38.
Grab the next digit (6) from the dividend, add it to 38, then carry on: 386 / 72

On to step 4:
72 can be fit into 386 5 times, resulting in a remainder of 26.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
Subtracting 360 from 386 leaves us with 26.
Bring next digit (4) of the dividend behind the 26 and repeat the process: 264 / 72

Moving on to step 5:
The number 72 fits into 264 3 times, leaving a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 953.0
Deduct 216 from 264 and we're left with 48.
Include the next digit (7) from the dividend after 48, then repeat: 487 / 72

Let's proceed to step 6:
If we divide 487 by 72, we get 6 and a remainder of 55.
The number 6 becomes the next digit in our result. 
Result so far: 9536.0
If we take 432 away from 487, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 7:
72 goes into 550 7 times with a remainder of 46.
The next digit of our result is 7. 
Result so far: 9536.7
Deduct 504 from 550 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 8:
460 divided by 72 is 6 with a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 9536.76
If we subtract 432 from 460, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
The number 72 fits into 280 3 times, leaving a remainder of 64.
The next digit of our result is 3. 
Result so far: 9536.763
The remainder is 64 after subtracting 216 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 10:
72 can be fit into 640 8 times, resulting in a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 9536.7638
If we take 576 away from 640, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 11:
The number 72 fits into 640 8 times, leaving a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 9536.76388
Subtracting 576 from 640 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 9536.76388, and the remainder is 6.4e-05.
