24686973 ÷ 489 
The aim is to understand the frequency of 489 in 24686973.

On to step 1:
2 divided by 489 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 489

Moving on to step 2:
When dividing 24 by 489, we get 0 with a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 24 and we're left with 24.
Append the next digit (6) from the dividend to 24 and continue with: 246 / 489

Step 3:
246 divided by 489 is 0 with a remainder of 246.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 246, we get 246.
Append the next digit (8) from the dividend to 246 and continue with: 2468 / 489

Advancing to step 4:
The number 489 fits into 2468 5 times, leaving a remainder of 23.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 2445 from 2468 and we're left with 23.
Bring next digit (6) of the dividend behind the 23 and repeat the process: 236 / 489

On to step 5:
236 divided by 489 is 0 with a remainder of 236.
The next digit of our result is 0. 
Result so far: 50.0
Subtracting 0 from 236 leaves us with 236.
Include the next digit (9) from the dividend after 236, then repeat: 2369 / 489

Step 6:
When dividing 2369 by 489, we get 4 with a remainder of 413.
The next digit of our result is 4. 
Result so far: 504.0
The remainder is 413 after subtracting 1956 from 2369.
Take the next digit (7) from the dividend and append it to 413, then repeat: 4137 / 489

Step 7:
When dividing 4137 by 489, we get 8 with a remainder of 225.
Put 8 as the next digit of the answer. 
Result so far: 5048.0
If we subtract 3912 from 4137, we get 225.
Bring next digit (3) of the dividend behind the 225 and repeat the process: 2253 / 489

Advancing to step 8:
If we divide 2253 by 489, we get 4 and a remainder of 297.
Use 4 as the next digit of our solution. 
Result so far: 50484.0
Subtract 1956 from 2253 to get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Going ahead to step 9:
2970 divided by 489 is 6 with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 50484.6
If we take 2934 away from 2970, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 10:
489 goes into 360 0 times with a remainder of 360.
The next digit of our result is 0. 
Result so far: 50484.6
Subtract 0 from 360 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 11:
When dividing 3600 by 489, we get 7 with a remainder of 177.
Use 7 as the next digit of our solution. 
Result so far: 50484.607
If we take 3423 away from 3600, we end up with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

On to step 12:
The number 489 fits into 1770 3 times, leaving a remainder of 303.
Record the quotient 3 as the next digit in the result. 
Result so far: 50484.6073
If we take 1467 away from 1770, we end up with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Moving on to step 13:
3030 divided by 489 is 6 with a remainder of 96.
Use 6 as the next digit of our solution. 
Result so far: 50484.60736
Subtracting 2934 from 3030 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 14:
489 can be fit into 960 1 times, resulting in a remainder of 471.
The number 1 becomes the next digit in our result. 
Result so far: 50484.607361
The remainder is 471 after subtracting 489 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Moving on to step 15:
The number 489 fits into 4710 9 times, leaving a remainder of 309.
Put 9 as the next digit of the answer. 
Result so far: 50484.6073619
Subtracting 4401 from 4710 leaves us with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Advancing to step 16:
When dividing 3090 by 489, we get 6 with a remainder of 156.
Record the quotient 6 as the next digit in the result. 
Result so far: 50484.60736196
Subtracting 2934 from 3090 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

After the division, we end up with 50484.60736196 and a remainder of 1.56e-07.
