196591 ÷ 77 
The aim is to understand the frequency of 77 in 196591.

Going ahead to step 1:
The number 77 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 77

Step 2:
The number 77 fits into 19 0 times, leaving a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Grab the next digit (6) from the dividend, add it to 19, then carry on: 196 / 77

Step 3:
When dividing 196 by 77, we get 2 with a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 42 after subtracting 154 from 196.
Bring next digit (5) of the dividend behind the 42 and repeat the process: 425 / 77

Going ahead to step 4:
77 can be fit into 425 5 times, resulting in a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we take 385 away from 425, we end up with 40.
Include the next digit (9) from the dividend after 40, then repeat: 409 / 77

On to step 5:
77 goes into 409 5 times with a remainder of 24.
Put 5 as the next digit of the answer. 
Result so far: 255.0
Subtracting 385 from 409 leaves us with 24.
Include the next digit (1) from the dividend after 24, then repeat: 241 / 77

Step 6:
If we divide 241 by 77, we get 3 and a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 2553.0
Deduct 231 from 241 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
77 goes into 100 1 times with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 2553.1
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.

Step 8:
230 divided by 77 is 2 with a remainder of 76.
Put 2 as the next digit of the answer. 
Result so far: 2553.12
The remainder is 76 after subtracting 154 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 9:
77 can be fit into 760 9 times, resulting in a remainder of 67.
Record the quotient 9 as the next digit in the result. 
Result so far: 2553.129
The remainder is 67 after subtracting 693 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 10:
When dividing 670 by 77, we get 8 with a remainder of 54.
Write down 8 as next digit of the result. 
Result so far: 2553.1298
If we subtract 616 from 670, we get 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 11:
The number 77 fits into 540 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 2553.12987
If we take 539 away from 540, we end up with 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 12:
10 divided by 77 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 2553.12987
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.

Let's proceed to step 13:
77 can be fit into 100 1 times, resulting in a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 2553.1298701
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.

Advancing to step 14:
77 can be fit into 230 2 times, resulting in a remainder of 76.
Use 2 as the next digit of our solution. 
Result so far: 2553.12987012
Deduct 154 from 230 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

In conclusion, the division gives 2553.12987012 with a balance of 7.6e-08.
