We're dividing 78188 by 51 
The aim is to understand the frequency of 51 in 78188.

Step 1:
51 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 51

Step 2:
51 goes into 78 1 times with a remainder of 27.
The next digit of our result is 1. 
Result so far: 1.0
If we take 51 away from 78, we end up with 27.
Append the next digit (1) from the dividend to 27 and continue with: 271 / 51

Step 3:
271 divided by 51 is 5 with a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we subtract 255 from 271, we get 16.
Append the next digit (8) from the dividend to 16 and continue with: 168 / 51

Advancing to step 4:
51 goes into 168 3 times with a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 153.0
Subtract 153 from 168 to get 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 51

Step 5:
158 divided by 51 is 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 1533.0
If we take 153 away from 158, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 6:
51 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 1533.0
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 7:
51 goes into 500 9 times with a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 1533.09
If we subtract 459 from 500, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 8:
410 divided by 51 is 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 1533.098
Subtracting 408 from 410 leaves us 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 9:
When dividing 20 by 51, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 1533.098
If we subtract 0 from 20, we get 20.
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 10:
The number 51 fits into 200 3 times, leaving a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 1533.09803
The remainder is 47 after subtracting 153 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 11:
470 divided by 51 is 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 1533.098039
Subtracting 459 from 470 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 12:
If we divide 110 by 51, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 1533.0980392
If we take 102 away from 110, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
The number 51 fits into 80 1 times, leaving a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 1533.09803921
Subtracting 51 from 80 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

In conclusion, the division gives 1533.09803921 with a balance of 2.9e-08.
