We're dividing 678557 by 77 
The aim is to understand the frequency of 77 in 678557.

On to step 1:
6 divided by 77 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 77

Going ahead to step 2:
77 goes into 67 0 times with a remainder of 67.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 67 after subtracting 0 from 67.
Take the next digit (8) from the dividend and append it to 67, then repeat: 678 / 77

On to step 3:
77 goes into 678 8 times with a remainder of 62.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 616 from 678 and we're left with 62.
Grab the next digit (5) from the dividend, add it to 62, then carry on: 625 / 77

Let's proceed to step 4:
The number 77 fits into 625 8 times, leaving a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
The remainder is 9 after subtracting 616 from 625.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 77

Step 5:
77 goes into 95 1 times with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 881.0
Subtract 77 from 95 to get 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 77

Step 6:
77 goes into 187 2 times with a remainder of 33.
Write down 2 as next digit of the result. 
Result so far: 8812.0
Deduct 154 from 187 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 7:
77 can be fit into 330 4 times, resulting in a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 8812.4
Subtracting 308 from 330 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 8:
77 goes into 220 2 times with a remainder of 66.
The next digit of our result is 2. 
Result so far: 8812.42
Deduct 154 from 220 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 9:
77 goes into 660 8 times with a remainder of 44.
The next digit of our result is 8. 
Result so far: 8812.428
Deduct 616 from 660 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 10:
77 goes into 440 5 times with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 8812.4285
Subtracting 385 from 440 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 11:
If we divide 550 by 77, we get 7 and a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 8812.42857
Deduct 539 from 550 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 12:
77 can be fit into 110 1 times, resulting in a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 8812.428571
If we take 77 away from 110, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 13:
The number 77 fits into 330 4 times, leaving a remainder of 22.
The next digit of our result is 4. 
Result so far: 8812.4285714
The remainder is 22 after subtracting 308 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 14:
If we divide 220 by 77, we get 2 and a remainder of 66.
Write down 2 as next digit of the result. 
Result so far: 8812.42857142
Subtracting 154 from 220 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

In conclusion, the division gives 8812.42857142 with a balance of 6.6e-08.
