3955141 divided by 102 
The aim is to understand the frequency of 102 in 3955141.

Step 1:
The number 102 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 102

Let's proceed to step 2:
The number 102 fits into 39 0 times, leaving a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Take the next digit (5) from the dividend and append it to 39, then repeat: 395 / 102

Going ahead to step 3:
395 divided by 102 is 3 with a remainder of 89.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 306 from 395 to get 89.
Bring next digit (5) of the dividend behind the 89 and repeat the process: 895 / 102

Going ahead to step 4:
102 goes into 895 8 times with a remainder of 79.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
If we take 816 away from 895, we end up with 79.
Append the next digit (1) from the dividend to 79 and continue with: 791 / 102

Moving on to step 5:
When dividing 791 by 102, we get 7 with a remainder of 77.
The next digit of our result is 7. 
Result so far: 387.0
Deduct 714 from 791 and we're left with 77.
Grab the next digit (4) from the dividend, add it to 77, then carry on: 774 / 102

Advancing to step 6:
102 goes into 774 7 times with a remainder of 60.
Record the quotient 7 as the next digit in the result. 
Result so far: 3877.0
If we take 714 away from 774, we end up with 60.
Append the next digit (1) from the dividend to 60 and continue with: 601 / 102

Step 7:
601 divided by 102 is 5 with a remainder of 91.
Use 5 as the next digit of our solution. 
Result so far: 38775.0
Subtracting 510 from 601 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Step 8:
The number 102 fits into 910 8 times, leaving a remainder of 94.
Write down 8 as next digit of the result. 
Result so far: 38775.8
The remainder is 94 after subtracting 816 from 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 9:
102 can be fit into 940 9 times, resulting in a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 38775.89
Deduct 918 from 940 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 10:
102 can be fit into 220 2 times, resulting in a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 38775.892
If we take 204 away from 220, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
The number 102 fits into 160 1 times, leaving a remainder of 58.
Write down 1 as next digit of the result. 
Result so far: 38775.8921
Subtract 102 from 160 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 12:
580 divided by 102 is 5 with a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 38775.89215
If we subtract 510 from 580, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 13:
If we divide 700 by 102, we get 6 and a remainder of 88.
The number 6 becomes the next digit in our result. 
Result so far: 38775.892156
Deduct 612 from 700 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 14:
If we divide 880 by 102, we get 8 and a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 38775.8921568
Subtract 816 from 880 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 15:
640 divided by 102 is 6 with a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 38775.89215686
Deduct 612 from 640 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 38775.89215686 with a remainder of 2.8e-08.
