We look at the division of 57357 by 79 
The aim is to understand the frequency of 79 in 57357.

Step 1:
The number 79 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 79

Let's proceed to step 2:
79 goes into 57 0 times with a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Append the next digit (3) from the dividend to 57 and continue with: 573 / 79

Advancing to step 3:
79 can be fit into 573 7 times, resulting in a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 553 from 573 leaves us with 20.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 79

Step 4:
If we divide 205 by 79, we get 2 and a remainder of 47.
Write down 2 as next digit of the result. 
Result so far: 72.0
If we take 158 away from 205, we end up with 47.
Bring next digit (7) of the dividend behind the 47 and repeat the process: 477 / 79

Advancing to step 5:
477 divided by 79 is 6 with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 726.0
If we subtract 474 from 477, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 6:
The number 79 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 726.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
If we divide 300 by 79, we get 3 and a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 726.03
Subtracting 237 from 300 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 8:
630 divided by 79 is 7 with a remainder of 77.
The next digit of our result is 7. 
Result so far: 726.037
If we take 553 away from 630, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 9:
79 goes into 770 9 times with a remainder of 59.
The next digit of our result is 9. 
Result so far: 726.0379
Subtract 711 from 770 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 10:
When dividing 590 by 79, we get 7 with a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 726.03797
If we take 553 away from 590, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 11:
When dividing 370 by 79, we get 4 with a remainder of 54.
The next digit of our result is 4. 
Result so far: 726.037974
The remainder is 54 after subtracting 316 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 12:
79 goes into 540 6 times with a remainder of 66.
Record the quotient 6 as the next digit in the result. 
Result so far: 726.0379746
Subtract 474 from 540 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 13:
79 can be fit into 660 8 times, resulting in a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 726.03797468
Subtract 632 from 660 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 726.03797468 and a remainder of 2.8e-08.
