77902 divided by 72 
We want to figure out the number of times 77902 can be divided by 72.

Step 1:
The number 72 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
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:
If we divide 77 by 72, we get 1 and a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 5 after subtracting 72 from 77.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 72

Let's proceed to step 3:
59 divided by 72 is 0 with a remainder of 59.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 59 to get 59.
Grab the next digit (0) from the dividend, add it to 59, then carry on: 590 / 72

On to step 4:
The number 72 fits into 590 8 times, leaving a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 108.0
If we take 576 away from 590, we end up with 14.
Fetch the next digit (2) from the dividend, attach it to 14 and continue: 142 / 72

On to step 5:
When dividing 142 by 72, we get 1 with a remainder of 70.
The number 1 becomes the next digit in our result. 
Result so far: 1081.0
The remainder is 70 after subtracting 72 from 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 6:
72 goes into 700 9 times with a remainder of 52.
Use 9 as the next digit of our solution. 
Result so far: 1081.9
Deduct 648 from 700 and we're left 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.

Going ahead to step 7:
72 can be fit into 520 7 times, resulting in a remainder of 16.
The next digit of our result is 7. 
Result so far: 1081.97
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.

Moving on to step 8:
When dividing 160 by 72, we get 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 1081.972
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 9:
72 goes into 160 2 times with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 1081.9722
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.

The final result is 1081.9722 with a remainder of 0.00016.
