We look at the division of 923489 by 79 
The aim is to understand the frequency of 79 in 923489.

On to step 1:
When dividing 9 by 79, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 79

Let's proceed to step 2:
92 divided by 79 is 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 13 after subtracting 79 from 92.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 79

Moving on to step 3:
The number 79 fits into 133 1 times, leaving a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 79 from 133, we get 54.
Include the next digit (4) from the dividend after 54, then repeat: 544 / 79

Let's proceed to step 4:
79 can be fit into 544 6 times, resulting in a remainder of 70.
Write down 6 as next digit of the result. 
Result so far: 116.0
Subtract 474 from 544 to get 70.
Include the next digit (8) from the dividend after 70, then repeat: 708 / 79

Advancing to step 5:
When dividing 708 by 79, we get 8 with a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 1168.0
The remainder is 76 after subtracting 632 from 708.
Append the next digit (9) from the dividend to 76 and continue with: 769 / 79

Advancing to step 6:
769 divided by 79 is 9 with a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 11689.0
If we take 711 away from 769, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 7:
If we divide 580 by 79, we get 7 and a remainder of 27.
The next digit of our result is 7. 
Result so far: 11689.7
Deduct 553 from 580 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 8:
79 goes into 270 3 times with a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 11689.73
Subtract 237 from 270 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 9:
When dividing 330 by 79, we get 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 11689.734
If we subtract 316 from 330, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 10:
When dividing 140 by 79, we get 1 with a remainder of 61.
Record the quotient 1 as the next digit in the result. 
Result so far: 11689.7341
Deduct 79 from 140 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 11:
79 goes into 610 7 times with a remainder of 57.
Write down 7 as next digit of the result. 
Result so far: 11689.73417
Subtract 553 from 610 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 12:
79 can be fit into 570 7 times, resulting in a remainder of 17.
The next digit of our result is 7. 
Result so far: 11689.734177
Deduct 553 from 570 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

After the division, we end up with 11689.734177 and a remainder of 1.7e-06.
