We're dividing 764610 by 77 
The aim is to understand the frequency of 77 in 764610.

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
Subtracting 0 from 7 leaves us with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 77

Step 2:
77 goes into 76 0 times with a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Grab the next digit (4) from the dividend, add it to 76, then carry on: 764 / 77

On to step 3:
77 can be fit into 764 9 times, resulting in a remainder of 71.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 693 from 764, we get 71.
Bring next digit (6) of the dividend behind the 71 and repeat the process: 716 / 77

Going ahead to step 4:
When dividing 716 by 77, we get 9 with a remainder of 23.
The next digit of our result is 9. 
Result so far: 99.0
Subtract 693 from 716 to get 23.
Bring next digit (1) of the dividend behind the 23 and repeat the process: 231 / 77

Step 5:
If we divide 231 by 77, we get 3 and a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 993.0
Subtract 231 from 231 to get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 77

On to step 6:
0 divided by 77 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 9930.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
77 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 9930.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
77 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9930.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 9930.0, with a leftover of 0.0.
