72320 divided by 77 
Let's see how many times 77 fits into 72320.

Moving on to step 1:
77 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 77

Step 2:
The number 77 fits into 72 0 times, leaving a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Take the next digit (3) from the dividend and append it to 72, then repeat: 723 / 77

Going ahead to step 3:
77 goes into 723 9 times with a remainder of 30.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 693 from 723 and we're left with 30.
Bring next digit (2) of the dividend behind the 30 and repeat the process: 302 / 77

Moving on to step 4:
If we divide 302 by 77, we get 3 and a remainder of 71.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
If we take 231 away from 302, we end up with 71.
Append the next digit (0) from the dividend to 71 and continue with: 710 / 77

On to step 5:
77 can be fit into 710 9 times, resulting in a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 939.0
If we subtract 693 from 710, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 6:
If we divide 170 by 77, we get 2 and a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 939.2
Deduct 154 from 170 and we're left 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.

Advancing to step 7:
The number 77 fits into 160 2 times, leaving a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 939.22
If we take 154 away from 160, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 939.22, and the remainder is 0.006.
