77977814 ÷ 102 
The aim is to understand the frequency of 102 in 77977814.

Going ahead to step 1:
102 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 102

Moving on to step 2:
If we divide 77 by 102, we get 0 and a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Take the next digit (9) from the dividend and append it to 77, then repeat: 779 / 102

Moving on to step 3:
The number 102 fits into 779 7 times, leaving a remainder of 65.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 714 from 779 to get 65.
Include the next digit (7) from the dividend after 65, then repeat: 657 / 102

Step 4:
When dividing 657 by 102, we get 6 with a remainder of 45.
Put 6 as the next digit of the answer. 
Result so far: 76.0
If we subtract 612 from 657, we get 45.
Bring next digit (7) of the dividend behind the 45 and repeat the process: 457 / 102

Going ahead to step 5:
If we divide 457 by 102, we get 4 and a remainder of 49.
Put 4 as the next digit of the answer. 
Result so far: 764.0
The remainder is 49 after subtracting 408 from 457.
Include the next digit (8) from the dividend after 49, then repeat: 498 / 102

Moving on to step 6:
102 goes into 498 4 times with a remainder of 90.
Put 4 as the next digit of the answer. 
Result so far: 7644.0
The remainder is 90 after subtracting 408 from 498.
Take the next digit (1) from the dividend and append it to 90, then repeat: 901 / 102

Advancing to step 7:
102 can be fit into 901 8 times, resulting in a remainder of 85.
Record the quotient 8 as the next digit in the result. 
Result so far: 76448.0
The remainder is 85 after subtracting 816 from 901.
Bring next digit (4) of the dividend behind the 85 and repeat the process: 854 / 102

Let's proceed to step 8:
102 goes into 854 8 times with a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 764488.0
The remainder is 38 after subtracting 816 from 854.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 9:
If we divide 380 by 102, we get 3 and a remainder of 74.
The number 3 becomes the next digit in our result. 
Result so far: 764488.3
Deduct 306 from 380 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 10:
When dividing 740 by 102, we get 7 with a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 764488.37
Subtracting 714 from 740 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 11:
When dividing 260 by 102, we get 2 with a remainder of 56.
Put 2 as the next digit of the answer. 
Result so far: 764488.372
If we take 204 away from 260, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 12:
The number 102 fits into 560 5 times, leaving a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 764488.3725
If we take 510 away from 560, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 13:
102 can be fit into 500 4 times, resulting in a remainder of 92.
Use 4 as the next digit of our solution. 
Result so far: 764488.37254
Deduct 408 from 500 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 14:
920 divided by 102 is 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 764488.372549
If we take 918 away from 920, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 15:
If we divide 20 by 102, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 764488.372549
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.

Let's proceed to step 16:
200 divided by 102 is 1 with a remainder of 98.
Use 1 as the next digit of our solution. 
Result so far: 764488.37254901
Subtracting 102 from 200 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

The final outcome is 764488.37254901, with a leftover of 9.8e-08.
