We're dividing 27251954 by 489 
The aim is to understand the frequency of 489 in 27251954.

Let's proceed to step 1:
When dividing 2 by 489, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 489

Let's proceed to step 2:
489 can be fit into 27 0 times, resulting in a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 27 leaves us with 27.
Fetch the next digit (2) from the dividend, attach it to 27 and continue: 272 / 489

Step 3:
489 can be fit into 272 0 times, resulting in a remainder of 272.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 272 after subtracting 0 from 272.
Fetch the next digit (5) from the dividend, attach it to 272 and continue: 2725 / 489

Advancing to step 4:
489 can be fit into 2725 5 times, resulting in a remainder of 280.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 2445 from 2725, we get 280.
Append the next digit (1) from the dividend to 280 and continue with: 2801 / 489

Step 5:
If we divide 2801 by 489, we get 5 and a remainder of 356.
Put 5 as the next digit of the answer. 
Result so far: 55.0
Deduct 2445 from 2801 and we're left with 356.
Take the next digit (9) from the dividend and append it to 356, then repeat: 3569 / 489

Moving on to step 6:
When dividing 3569 by 489, we get 7 with a remainder of 146.
Write down 7 as next digit of the result. 
Result so far: 557.0
If we subtract 3423 from 3569, we get 146.
Append the next digit (5) from the dividend to 146 and continue with: 1465 / 489

Advancing to step 7:
When dividing 1465 by 489, we get 2 with a remainder of 487.
Put 2 as the next digit of the answer. 
Result so far: 5572.0
Subtract 978 from 1465 to get 487.
Append the next digit (4) from the dividend to 487 and continue with: 4874 / 489

Let's proceed to step 8:
If we divide 4874 by 489, we get 9 and a remainder of 473.
Use 9 as the next digit of our solution. 
Result so far: 55729.0
Deduct 4401 from 4874 and we're left with 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Moving on to step 9:
489 can be fit into 4730 9 times, resulting in a remainder of 329.
Record the quotient 9 as the next digit in the result. 
Result so far: 55729.9
If we subtract 4401 from 4730, we get 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Step 10:
3290 divided by 489 is 6 with a remainder of 356.
Write down 6 as next digit of the result. 
Result so far: 55729.96
The remainder is 356 after subtracting 2934 from 3290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Moving on to step 11:
3560 divided by 489 is 7 with a remainder of 137.
The number 7 becomes the next digit in our result. 
Result so far: 55729.967
If we subtract 3423 from 3560, we get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Step 12:
The number 489 fits into 1370 2 times, leaving a remainder of 392.
Use 2 as the next digit of our solution. 
Result so far: 55729.9672
If we subtract 978 from 1370, we get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Moving on to step 13:
When dividing 3920 by 489, we get 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 55729.96728
The remainder is 8 after subtracting 3912 from 3920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 14:
489 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 55729.96728
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 15:
489 goes into 800 1 times with a remainder of 311.
Write down 1 as next digit of the result. 
Result so far: 55729.9672801
If we subtract 489 from 800, we get 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Advancing to step 16:
489 goes into 3110 6 times with a remainder of 176.
Record the quotient 6 as the next digit in the result. 
Result so far: 55729.96728016
The remainder is 176 after subtracting 2934 from 3110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

The final outcome is 55729.96728016, with a leftover of 1.76e-07.
