We look at the division of 75367748 by 79 
The aim is to understand the frequency of 79 in 75367748.

Advancing to step 1:
7 divided by 79 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 79

Step 2:
The number 79 fits into 75 0 times, leaving a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Grab the next digit (3) from the dividend, add it to 75, then carry on: 753 / 79

Step 3:
If we divide 753 by 79, we get 9 and a remainder of 42.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 711 from 753 leaves us with 42.
Append the next digit (6) from the dividend to 42 and continue with: 426 / 79

Going ahead to step 4:
When dividing 426 by 79, we get 5 with a remainder of 31.
Use 5 as the next digit of our solution. 
Result so far: 95.0
If we subtract 395 from 426, we get 31.
Take the next digit (7) from the dividend and append it to 31, then repeat: 317 / 79

On to step 5:
If we divide 317 by 79, we get 4 and a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 954.0
Subtracting 316 from 317 leaves us with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 79

Let's proceed to step 6:
17 divided by 79 is 0 with a remainder of 17.
The next digit of our result is 0. 
Result so far: 9540.0
Deduct 0 from 17 and we're left with 17.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 79

Going ahead to step 7:
79 goes into 174 2 times with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 95402.0
The remainder is 16 after subtracting 158 from 174.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 79

On to step 8:
The number 79 fits into 168 2 times, leaving a remainder of 10.
The next digit of our result is 2. 
Result so far: 954022.0
If we take 158 away from 168, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
100 divided by 79 is 1 with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 954022.1
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 10:
210 divided by 79 is 2 with a remainder of 52.
Use 2 as the next digit of our solution. 
Result so far: 954022.12
If we subtract 158 from 210, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 11:
If we divide 520 by 79, we get 6 and a remainder of 46.
Record the quotient 6 as the next digit in the result. 
Result so far: 954022.126
Subtracting 474 from 520 leaves us 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.

Moving on to step 12:
If we divide 460 by 79, we get 5 and a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 954022.1265
If we take 395 away from 460, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 13:
When dividing 650 by 79, we get 8 with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 954022.12658
If we take 632 away from 650, we end up 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 14:
When dividing 180 by 79, we get 2 with a remainder of 22.
The next digit of our result is 2. 
Result so far: 954022.126582
Subtracting 158 from 180 leaves us 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.

Step 15:
If we divide 220 by 79, we get 2 and a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 954022.1265822
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 final outcome is 954022.1265822, with a leftover of 6.2e-07.
