Let's divide 779750 by 77
The aim is to understand the frequency of 77 in 779750.

Advancing to step 1:
If we divide 7 by 77, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 77

Going ahead to step 2:
77 can be fit into 77 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 77 from 77 to get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 77

Step 3:
77 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 77

Advancing to step 4:
97 divided by 77 is 1 with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 101.0
Subtracting 77 from 97 leaves us with 20.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 77

Let's proceed to step 5:
77 can be fit into 205 2 times, resulting in a remainder of 51.
Put 2 as the next digit of the answer. 
Result so far: 1012.0
Subtract 154 from 205 to get 51.
Append the next digit (0) from the dividend to 51 and continue with: 510 / 77

Advancing to step 6:
510 divided by 77 is 6 with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 10126.0
If we take 462 away from 510, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 7:
77 goes into 480 6 times with a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 10126.6
The remainder is 18 after subtracting 462 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
When dividing 180 by 77, we get 2 with a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 10126.62
If we subtract 154 from 180, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 9:
If we divide 260 by 77, we get 3 and a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 10126.623
Deduct 231 from 260 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 10:
If we divide 290 by 77, we get 3 and a remainder of 59.
Use 3 as the next digit of our solution. 
Result so far: 10126.6233
If we subtract 231 from 290, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

The quotient of the division is 10126.6233, and the remainder is 0.00059.
