We look at the division of 79871512 by 102 
The aim is to understand the frequency of 102 in 79871512.

Step 1:
102 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 102

Advancing to step 2:
When dividing 79 by 102, we get 0 with a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Grab the next digit (8) from the dividend, add it to 79, then carry on: 798 / 102

Let's proceed to step 3:
102 can be fit into 798 7 times, resulting in a remainder of 84.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 714 from 798 and we're left with 84.
Append the next digit (7) from the dividend to 84 and continue with: 847 / 102

On to step 4:
If we divide 847 by 102, we get 8 and a remainder of 31.
Write down 8 as next digit of the result. 
Result so far: 78.0
Subtract 816 from 847 to get 31.
Fetch the next digit (1) from the dividend, attach it to 31 and continue: 311 / 102

Moving on to step 5:
When dividing 311 by 102, we get 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 783.0
If we subtract 306 from 311, we get 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 102

Let's proceed to step 6:
If we divide 55 by 102, we get 0 and a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 7830.0
If we subtract 0 from 55, we get 55.
Include the next digit (1) from the dividend after 55, then repeat: 551 / 102

Advancing to step 7:
When dividing 551 by 102, we get 5 with a remainder of 41.
Write down 5 as next digit of the result. 
Result so far: 78305.0
If we subtract 510 from 551, we get 41.
Grab the next digit (2) from the dividend, add it to 41, then carry on: 412 / 102

Advancing to step 8:
The number 102 fits into 412 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 783054.0
Subtracting 408 from 412 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
When dividing 40 by 102, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 783054.0
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
400 divided by 102 is 3 with a remainder of 94.
The next digit of our result is 3. 
Result so far: 783054.03
Subtract 306 from 400 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 11:
102 can be fit into 940 9 times, resulting in a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 783054.039
Subtract 918 from 940 to get 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 12:
102 goes into 220 2 times with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 783054.0392
Deduct 204 from 220 and we're left 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.

Going ahead to step 13:
When dividing 160 by 102, we get 1 with a remainder of 58.
Use 1 as the next digit of our solution. 
Result so far: 783054.03921
Deduct 102 from 160 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 14:
580 divided by 102 is 5 with a remainder of 70.
The next digit of our result is 5. 
Result so far: 783054.039215
The remainder is 70 after subtracting 510 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 15:
The number 102 fits into 700 6 times, leaving a remainder of 88.
Record the quotient 6 as the next digit in the result. 
Result so far: 783054.0392156
Subtracting 612 from 700 leaves us 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.

Step 16:
102 goes into 880 8 times with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 783054.03921568
The remainder is 64 after subtracting 816 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

In conclusion, the division gives 783054.03921568 with a balance of 6.4e-08.
