2480872 ÷ 489 
The aim is to understand the frequency of 489 in 2480872.

Moving on to step 1:
When dividing 2 by 489, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 489

Let's proceed to step 2:
489 goes into 24 0 times with a remainder of 24.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 24 to get 24.
Grab the next digit (8) from the dividend, add it to 24, then carry on: 248 / 489

Moving on to step 3:
489 goes into 248 0 times with a remainder of 248.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 248, we get 248.
Append the next digit (0) from the dividend to 248 and continue with: 2480 / 489

Advancing to step 4:
When dividing 2480 by 489, we get 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 2445 from 2480 leaves us with 35.
Append the next digit (8) from the dividend to 35 and continue with: 358 / 489

Going ahead to step 5:
358 divided by 489 is 0 with a remainder of 358.
Write down 0 as next digit of the result. 
Result so far: 50.0
If we take 0 away from 358, we end up with 358.
Include the next digit (7) from the dividend after 358, then repeat: 3587 / 489

Advancing to step 6:
489 can be fit into 3587 7 times, resulting in a remainder of 164.
The next digit of our result is 7. 
Result so far: 507.0
Subtracting 3423 from 3587 leaves us with 164.
Append the next digit (2) from the dividend to 164 and continue with: 1642 / 489

Going ahead to step 7:
The number 489 fits into 1642 3 times, leaving a remainder of 175.
The number 3 becomes the next digit in our result. 
Result so far: 5073.0
Deduct 1467 from 1642 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 8:
The number 489 fits into 1750 3 times, leaving a remainder of 283.
Record the quotient 3 as the next digit in the result. 
Result so far: 5073.3
Subtract 1467 from 1750 to get 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

On to step 9:
When dividing 2830 by 489, we get 5 with a remainder of 385.
Record the quotient 5 as the next digit in the result. 
Result so far: 5073.35
The remainder is 385 after subtracting 2445 from 2830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Step 10:
The number 489 fits into 3850 7 times, leaving a remainder of 427.
Use 7 as the next digit of our solution. 
Result so far: 5073.357
If we subtract 3423 from 3850, we get 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

Going ahead to step 11:
The number 489 fits into 4270 8 times, leaving a remainder of 358.
Write down 8 as next digit of the result. 
Result so far: 5073.3578
Subtracting 3912 from 4270 leaves us with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

On to step 12:
The number 489 fits into 3580 7 times, leaving a remainder of 157.
Use 7 as the next digit of our solution. 
Result so far: 5073.35787
Subtract 3423 from 3580 to get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

On to step 13:
489 can be fit into 1570 3 times, resulting in a remainder of 103.
The next digit of our result is 3. 
Result so far: 5073.357873
If we subtract 1467 from 1570, we get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Step 14:
When dividing 1030 by 489, we get 2 with a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 5073.3578732
If we subtract 978 from 1030, 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.

Step 15:
489 goes into 520 1 times with a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 5073.35787321
Subtracting 489 from 520 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

After the division, we end up with 5073.35787321 and a remainder of 3.1e-08.
