519020 divided by 79 
The aim is to understand the frequency of 79 in 519020.

Step 1:
When dividing 5 by 79, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 79

Let's proceed to step 2:
The number 79 fits into 51 0 times, leaving a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Bring next digit (9) of the dividend behind the 51 and repeat the process: 519 / 79

Let's proceed to step 3:
79 goes into 519 6 times with a remainder of 45.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 45 after subtracting 474 from 519.
Fetch the next digit (0) from the dividend, attach it to 45 and continue: 450 / 79

Let's proceed to step 4:
450 divided by 79 is 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
Subtract 395 from 450 to get 55.
Include the next digit (2) from the dividend after 55, then repeat: 552 / 79

Let's proceed to step 5:
When dividing 552 by 79, we get 6 with a remainder of 78.
The number 6 becomes the next digit in our result. 
Result so far: 656.0
Subtract 474 from 552 to get 78.
Bring next digit (0) of the dividend behind the 78 and repeat the process: 780 / 79

Let's proceed to step 6:
79 can be fit into 780 9 times, resulting in a remainder of 69.
Put 9 as the next digit of the answer. 
Result so far: 6569.0
Subtract 711 from 780 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 7:
The number 79 fits into 690 8 times, leaving a remainder of 58.
Use 8 as the next digit of our solution. 
Result so far: 6569.8
Subtract 632 from 690 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 8:
The number 79 fits into 580 7 times, leaving a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 6569.87
If we take 553 away from 580, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 9:
When dividing 270 by 79, we get 3 with a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 6569.873
If we take 237 away from 270, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 10:
If we divide 330 by 79, we get 4 and a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 6569.8734
Deduct 316 from 330 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 11:
79 can be fit into 140 1 times, resulting in a remainder of 61.
Record the quotient 1 as the next digit in the result. 
Result so far: 6569.87341
If we subtract 79 from 140, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 12:
The number 79 fits into 610 7 times, leaving a remainder of 57.
Use 7 as the next digit of our solution. 
Result so far: 6569.873417
Subtract 553 from 610 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 13:
79 can be fit into 570 7 times, resulting in a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 6569.8734177
Subtracting 553 from 570 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

In conclusion, the division gives 6569.8734177 with a balance of 1.7e-07.
