128533 divided by 77 
The aim is to understand the frequency of 77 in 128533.

Advancing to step 1:
77 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 77

Advancing to step 2:
If we divide 12 by 77, we get 0 and a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 77

Step 3:
77 goes into 128 1 times with a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 77 from 128 to get 51.
Fetch the next digit (5) from the dividend, attach it to 51 and continue: 515 / 77

On to step 4:
If we divide 515 by 77, we get 6 and a remainder of 53.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtract 462 from 515 to get 53.
Append the next digit (3) from the dividend to 53 and continue with: 533 / 77

Advancing to step 5:
When dividing 533 by 77, we get 6 with a remainder of 71.
The next digit of our result is 6. 
Result so far: 166.0
Subtracting 462 from 533 leaves us with 71.
Include the next digit (3) from the dividend after 71, then repeat: 713 / 77

Let's proceed to step 6:
713 divided by 77 is 9 with a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 1669.0
The remainder is 20 after subtracting 693 from 713.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
200 divided by 77 is 2 with a remainder of 46.
The next digit of our result is 2. 
Result so far: 1669.2
The remainder is 46 after subtracting 154 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 8:
77 goes into 460 5 times with a remainder of 75.
The next digit of our result is 5. 
Result so far: 1669.25
If we subtract 385 from 460, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 9:
77 can be fit into 750 9 times, resulting in a remainder of 57.
Put 9 as the next digit of the answer. 
Result so far: 1669.259
The remainder is 57 after subtracting 693 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 10:
If we divide 570 by 77, we get 7 and a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 1669.2597
If we subtract 539 from 570, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 11:
77 goes into 310 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 1669.25974
The remainder is 2 after subtracting 308 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 12:
20 divided by 77 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1669.25974
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
When dividing 200 by 77, we get 2 with a remainder of 46.
Put 2 as the next digit of the answer. 
Result so far: 1669.2597402
Subtract 154 from 200 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 14:
If we divide 460 by 77, we get 5 and a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 1669.25974025
If we subtract 385 from 460, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The quotient of the division is 1669.25974025, and the remainder is 7.5e-08.
