We look at the division of 7745724 by 102 
The aim is to understand the frequency of 102 in 7745724.

Advancing to step 1:
When dividing 7 by 102, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 102

Let's proceed to step 2:
When dividing 77 by 102, we get 0 with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Include the next digit (4) from the dividend after 77, then repeat: 774 / 102

Advancing to step 3:
774 divided by 102 is 7 with a remainder of 60.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 714 from 774 leaves us with 60.
Bring next digit (5) of the dividend behind the 60 and repeat the process: 605 / 102

Step 4:
When dividing 605 by 102, we get 5 with a remainder of 95.
The next digit of our result is 5. 
Result so far: 75.0
If we subtract 510 from 605, we get 95.
Append the next digit (7) from the dividend to 95 and continue with: 957 / 102

Moving on to step 5:
102 can be fit into 957 9 times, resulting in a remainder of 39.
The number 9 becomes the next digit in our result. 
Result so far: 759.0
Subtract 918 from 957 to get 39.
Take the next digit (2) from the dividend and append it to 39, then repeat: 392 / 102

Going ahead to step 6:
102 goes into 392 3 times with a remainder of 86.
Put 3 as the next digit of the answer. 
Result so far: 7593.0
Subtract 306 from 392 to get 86.
Include the next digit (4) from the dividend after 86, then repeat: 864 / 102

On to step 7:
If we divide 864 by 102, we get 8 and a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 75938.0
If we subtract 816 from 864, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 8:
102 goes into 480 4 times with a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 75938.4
Subtract 408 from 480 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 9:
720 divided by 102 is 7 with a remainder of 6.
The next digit of our result is 7. 
Result so far: 75938.47
The remainder is 6 after subtracting 714 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
If we divide 60 by 102, we get 0 and a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 75938.47
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 11:
102 can be fit into 600 5 times, resulting in a remainder of 90.
The number 5 becomes the next digit in our result. 
Result so far: 75938.4705
The remainder is 90 after subtracting 510 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 12:
The number 102 fits into 900 8 times, leaving a remainder of 84.
The next digit of our result is 8. 
Result so far: 75938.47058
If we subtract 816 from 900, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 13:
If we divide 840 by 102, we get 8 and a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 75938.470588
The remainder is 24 after subtracting 816 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 75938.470588, and the remainder is 2.4e-06.
