Let's divide 547702 by 77
The aim is to understand the frequency of 77 in 547702.

Let's proceed to step 1:
The number 77 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 77

Going ahead to step 2:
77 can be fit into 54 0 times, resulting in a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 54 after subtracting 0 from 54.
Append the next digit (7) from the dividend to 54 and continue with: 547 / 77

On to step 3:
If we divide 547 by 77, we get 7 and a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 539 from 547, we get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 77

On to step 4:
If we divide 87 by 77, we get 1 and a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 71.0
Subtract 77 from 87 to get 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 77

Step 5:
When dividing 100 by 77, we get 1 with a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 711.0
If we take 77 away from 100, we end up with 23.
Bring next digit (2) of the dividend behind the 23 and repeat the process: 232 / 77

On to step 6:
If we divide 232 by 77, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 7113.0
If we subtract 231 from 232, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
The number 77 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 7113.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
77 can be fit into 100 1 times, resulting in a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 7113.01
The remainder is 23 after subtracting 77 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 9:
When dividing 230 by 77, we get 2 with a remainder of 76.
The next digit of our result is 2. 
Result so far: 7113.012
If we subtract 154 from 230, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 10:
The number 77 fits into 760 9 times, leaving a remainder of 67.
Put 9 as the next digit of the answer. 
Result so far: 7113.0129
Deduct 693 from 760 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 11:
When dividing 670 by 77, we get 8 with a remainder of 54.
The number 8 becomes the next digit in our result. 
Result so far: 7113.01298
If we take 616 away from 670, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 12:
The number 77 fits into 540 7 times, leaving a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 7113.012987
If we subtract 539 from 540, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 13:
77 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 7113.012987
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 14:
100 divided by 77 is 1 with a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 7113.01298701
Deduct 77 from 100 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final result is 7113.01298701 with a remainder of 2.3e-08.
