We look at the division of 768578 by 79 
The aim is to understand the frequency of 79 in 768578.

Step 1:
79 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 79

Advancing to step 2:
76 divided by 79 is 0 with a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Append the next digit (8) from the dividend to 76 and continue with: 768 / 79

Moving on to step 3:
If we divide 768 by 79, we get 9 and a remainder of 57.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 57 after subtracting 711 from 768.
Append the next digit (5) from the dividend to 57 and continue with: 575 / 79

Advancing to step 4:
79 can be fit into 575 7 times, resulting in a remainder of 22.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
Subtract 553 from 575 to get 22.
Grab the next digit (7) from the dividend, add it to 22, then carry on: 227 / 79

Step 5:
The number 79 fits into 227 2 times, leaving a remainder of 69.
Write down 2 as next digit of the result. 
Result so far: 972.0
Deduct 158 from 227 and we're left with 69.
Take the next digit (8) from the dividend and append it to 69, then repeat: 698 / 79

Going ahead to step 6:
79 can be fit into 698 8 times, resulting in a remainder of 66.
Write down 8 as next digit of the result. 
Result so far: 9728.0
If we take 632 away from 698, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 7:
660 divided by 79 is 8 with a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 9728.8
Subtracting 632 from 660 leaves us 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.

Moving on to step 8:
If we divide 280 by 79, we get 3 and a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 9728.83
Subtracting 237 from 280 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 9:
79 can be fit into 430 5 times, resulting in a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 9728.835
Deduct 395 from 430 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 10:
When dividing 350 by 79, we get 4 with a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 9728.8354
If we subtract 316 from 350, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 11:
79 can be fit into 340 4 times, resulting in a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 9728.83544
Subtracting 316 from 340 leaves us with 24.
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 9728.83544, and the remainder is 2.4e-05.
