We're dividing 625359 by 77 
The aim is to understand the frequency of 77 in 625359.

Step 1:
If we divide 6 by 77, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 77

Going ahead to step 2:
If we divide 62 by 77, we get 0 and a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 62 leaves us with 62.
Include the next digit (5) from the dividend after 62, then repeat: 625 / 77

Going ahead to step 3:
77 can be fit into 625 8 times, resulting in a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 616 from 625 to get 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 77

Going ahead to step 4:
93 divided by 77 is 1 with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
If we take 77 away from 93, we end up with 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 77

Let's proceed to step 5:
77 goes into 165 2 times with a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 812.0
Subtract 154 from 165 to get 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 77

Step 6:
119 divided by 77 is 1 with a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 8121.0
If we take 77 away from 119, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 7:
77 goes into 420 5 times with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 8121.5
Subtracting 385 from 420 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 8:
77 can be fit into 350 4 times, resulting in a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 8121.54
Subtracting 308 from 350 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 9:
77 goes into 420 5 times with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 8121.545
If we take 385 away from 420, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 10:
350 divided by 77 is 4 with a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 8121.5454
If we subtract 308 from 350, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 11:
The number 77 fits into 420 5 times, leaving a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 8121.54545
If we take 385 away from 420, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 12:
The number 77 fits into 350 4 times, leaving a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 8121.545454
If we subtract 308 from 350, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 13:
77 can be fit into 420 5 times, resulting in a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 8121.5454545
If we take 385 away from 420, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 14:
77 goes into 350 4 times with a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 8121.54545454
If we take 308 away from 350, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

In conclusion, the division gives 8121.54545454 with a balance of 4.2e-08.
