We divide 72602 by 77
The aim is to understand the frequency of 77 in 72602.

Going ahead to step 1:
When dividing 7 by 77, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 77

Moving on to step 2:
When dividing 72 by 77, we get 0 with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Fetch the next digit (6) from the dividend, attach it to 72 and continue: 726 / 77

Moving on to step 3:
When dividing 726 by 77, we get 9 with a remainder of 33.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 693 from 726 to get 33.
Grab the next digit (0) from the dividend, add it to 33, then carry on: 330 / 77

Advancing to step 4:
When dividing 330 by 77, we get 4 with a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 94.0
Deduct 308 from 330 and we're left with 22.
Fetch the next digit (2) from the dividend, attach it to 22 and continue: 222 / 77

Step 5:
222 divided by 77 is 2 with a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 942.0
If we take 154 away from 222, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 6:
The number 77 fits into 680 8 times, leaving a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 942.8
Subtract 616 from 680 to get 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 7:
The number 77 fits into 640 8 times, leaving a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 942.88
If we subtract 616 from 640, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 942.88, and the remainder is 0.024.
