We look at the division of 408431 by 79 
The aim is to understand the frequency of 79 in 408431.

Moving on to step 1:
If we divide 4 by 79, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 79

Advancing to step 2:
79 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Fetch the next digit (8) from the dividend, attach it to 40 and continue: 408 / 79

Let's proceed to step 3:
The number 79 fits into 408 5 times, leaving a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 395 from 408, we get 13.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 79

Moving on to step 4:
If we divide 134 by 79, we get 1 and a remainder of 55.
Write down 1 as next digit of the result. 
Result so far: 51.0
If we subtract 79 from 134, we get 55.
Fetch the next digit (3) from the dividend, attach it to 55 and continue: 553 / 79

Advancing to step 5:
79 goes into 553 7 times with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 517.0
Subtracting 553 from 553 leaves us with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 79

Let's proceed to step 6:
The number 79 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 5170.0
If we subtract 0 from 1, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
79 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 5170.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
If we divide 100 by 79, we get 1 and a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 5170.01
If we subtract 79 from 100, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 9:
79 can be fit into 210 2 times, resulting in a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 5170.012
Subtracting 158 from 210 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 10:
520 divided by 79 is 6 with a remainder of 46.
Record the quotient 6 as the next digit in the result. 
Result so far: 5170.0126
If we take 474 away from 520, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 11:
460 divided by 79 is 5 with a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 5170.01265
Subtract 395 from 460 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 12:
79 goes into 650 8 times with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 5170.012658
Subtracting 632 from 650 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 13:
79 can be fit into 180 2 times, resulting in a remainder of 22.
The next digit of our result is 2. 
Result so far: 5170.0126582
Deduct 158 from 180 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 14:
220 divided by 79 is 2 with a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 5170.01265822
If we take 158 away from 220, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The quotient of the division is 5170.01265822, and the remainder is 6.2e-08.
