We look at the division of 754639 by 79 
The aim is to understand the frequency of 79 in 754639.

Advancing to step 1:
If we divide 7 by 79, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 79

Moving on to step 2:
When dividing 75 by 79, we get 0 with a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Append the next digit (4) from the dividend to 75 and continue with: 754 / 79

On to step 3:
79 goes into 754 9 times with a remainder of 43.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 43 after subtracting 711 from 754.
Bring next digit (6) of the dividend behind the 43 and repeat the process: 436 / 79

Going ahead to step 4:
If we divide 436 by 79, we get 5 and a remainder of 41.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
If we take 395 away from 436, we end up with 41.
Grab the next digit (3) from the dividend, add it to 41, then carry on: 413 / 79

On to step 5:
If we divide 413 by 79, we get 5 and a remainder of 18.
The next digit of our result is 5. 
Result so far: 955.0
If we take 395 away from 413, we end up with 18.
Append the next digit (9) from the dividend to 18 and continue with: 189 / 79

Step 6:
If we divide 189 by 79, we get 2 and a remainder of 31.
Record the quotient 2 as the next digit in the result. 
Result so far: 9552.0
If we subtract 158 from 189, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
79 goes into 310 3 times with a remainder of 73.
Write down 3 as next digit of the result. 
Result so far: 9552.3
If we take 237 away from 310, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 8:
When dividing 730 by 79, we get 9 with a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 9552.39
Deduct 711 from 730 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 9:
If we divide 190 by 79, we get 2 and a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 9552.392
The remainder is 32 after subtracting 158 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 10:
79 goes into 320 4 times with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 9552.3924
Deduct 316 from 320 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
79 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 9552.3924
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
When dividing 400 by 79, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 9552.392405
Subtract 395 from 400 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 13:
When dividing 50 by 79, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 9552.392405
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 14:
The number 79 fits into 500 6 times, leaving a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 9552.39240506
If we subtract 474 from 500, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final outcome is 9552.39240506, with a leftover of 2.6e-08.
