7720 ÷ 72 
We want to divide 7720 by 72.

Step 1:
If we divide 7 by 72, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 72

On to step 2:
When dividing 77 by 72, we get 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 72 away from 77, we end up with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 72

Advancing to step 3:
72 goes into 52 0 times with a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 52 to get 52.
Grab the next digit (0) from the dividend, add it to 52, then carry on: 520 / 72

On to step 4:
When dividing 520 by 72, we get 7 with a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 107.0
If we take 504 away from 520, 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.

On to step 5:
72 goes into 160 2 times with a remainder of 16.
The next digit of our result is 2. 
Result so far: 107.2
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 6:
When dividing 160 by 72, we get 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 107.22
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.

Our division results in 107.22 with a remaining 0.016.
