We look at the division of 79908859 by 489 
The aim is to understand the frequency of 489 in 79908859.

Going ahead to step 1:
When dividing 7 by 489, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 489

Step 2:
When dividing 79 by 489, we get 0 with a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Take the next digit (9) from the dividend and append it to 79, then repeat: 799 / 489

On to step 3:
When dividing 799 by 489, we get 1 with a remainder of 310.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 489 from 799 and we're left with 310.
Append the next digit (0) from the dividend to 310 and continue with: 3100 / 489

Step 4:
When dividing 3100 by 489, we get 6 with a remainder of 166.
The next digit of our result is 6. 
Result so far: 16.0
Subtract 2934 from 3100 to get 166.
Grab the next digit (8) from the dividend, add it to 166, then carry on: 1668 / 489

Going ahead to step 5:
489 can be fit into 1668 3 times, resulting in a remainder of 201.
Use 3 as the next digit of our solution. 
Result so far: 163.0
Deduct 1467 from 1668 and we're left with 201.
Fetch the next digit (8) from the dividend, attach it to 201 and continue: 2018 / 489

Advancing to step 6:
When dividing 2018 by 489, we get 4 with a remainder of 62.
The next digit of our result is 4. 
Result so far: 1634.0
Deduct 1956 from 2018 and we're left with 62.
Grab the next digit (5) from the dividend, add it to 62, then carry on: 625 / 489

Let's proceed to step 7:
When dividing 625 by 489, we get 1 with a remainder of 136.
The number 1 becomes the next digit in our result. 
Result so far: 16341.0
Subtract 489 from 625 to get 136.
Fetch the next digit (9) from the dividend, attach it to 136 and continue: 1369 / 489

Moving on to step 8:
489 can be fit into 1369 2 times, resulting in a remainder of 391.
Put 2 as the next digit of the answer. 
Result so far: 163412.0
If we take 978 away from 1369, we end up with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

On to step 9:
489 can be fit into 3910 7 times, resulting in a remainder of 487.
The number 7 becomes the next digit in our result. 
Result so far: 163412.7
Subtracting 3423 from 3910 leaves us with 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

Going ahead to step 10:
4870 divided by 489 is 9 with a remainder of 469.
Put 9 as the next digit of the answer. 
Result so far: 163412.79
Deduct 4401 from 4870 and we're left with 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

Step 11:
4690 divided by 489 is 9 with a remainder of 289.
The next digit of our result is 9. 
Result so far: 163412.799
The remainder is 289 after subtracting 4401 from 4690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

After the division, we end up with 163412.799 and a remainder of 0.0289.
