57528369 ÷ 489 
The aim is to understand the frequency of 489 in 57528369.

Advancing to step 1:
5 divided by 489 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 489

Step 2:
When dividing 57 by 489, we get 0 with a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Bring next digit (5) of the dividend behind the 57 and repeat the process: 575 / 489

On to step 3:
When dividing 575 by 489, we get 1 with a remainder of 86.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 489 from 575, we get 86.
Include the next digit (2) from the dividend after 86, then repeat: 862 / 489

Advancing to step 4:
489 can be fit into 862 1 times, resulting in a remainder of 373.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 489 from 862 leaves us with 373.
Grab the next digit (8) from the dividend, add it to 373, then carry on: 3738 / 489

Advancing to step 5:
If we divide 3738 by 489, we get 7 and a remainder of 315.
Record the quotient 7 as the next digit in the result. 
Result so far: 117.0
Deduct 3423 from 3738 and we're left with 315.
Append the next digit (3) from the dividend to 315 and continue with: 3153 / 489

Moving on to step 6:
489 can be fit into 3153 6 times, resulting in a remainder of 219.
Write down 6 as next digit of the result. 
Result so far: 1176.0
Subtracting 2934 from 3153 leaves us with 219.
Fetch the next digit (6) from the dividend, attach it to 219 and continue: 2196 / 489

Let's proceed to step 7:
489 goes into 2196 4 times with a remainder of 240.
The next digit of our result is 4. 
Result so far: 11764.0
Subtract 1956 from 2196 to get 240.
Take the next digit (9) from the dividend and append it to 240, then repeat: 2409 / 489

Let's proceed to step 8:
If we divide 2409 by 489, we get 4 and a remainder of 453.
Record the quotient 4 as the next digit in the result. 
Result so far: 117644.0
If we subtract 1956 from 2409, we get 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

On to step 9:
489 goes into 4530 9 times with a remainder of 129.
Use 9 as the next digit of our solution. 
Result so far: 117644.9
If we subtract 4401 from 4530, we get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Moving on to step 10:
1290 divided by 489 is 2 with a remainder of 312.
Use 2 as the next digit of our solution. 
Result so far: 117644.92
Subtracting 978 from 1290 leaves us with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Moving on to step 11:
When dividing 3120 by 489, we get 6 with a remainder of 186.
Record the quotient 6 as the next digit in the result. 
Result so far: 117644.926
Subtracting 2934 from 3120 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 12:
489 goes into 1860 3 times with a remainder of 393.
Put 3 as the next digit of the answer. 
Result so far: 117644.9263
If we subtract 1467 from 1860, we get 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Step 13:
When dividing 3930 by 489, we get 8 with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 117644.92638
Subtract 3912 from 3930 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 14:
489 can be fit into 180 0 times, resulting in a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 117644.92638
If we take 0 away from 180, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 15:
The number 489 fits into 1800 3 times, leaving a remainder of 333.
Put 3 as the next digit of the answer. 
Result so far: 117644.9263803
Deduct 1467 from 1800 and we're left with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Going ahead to step 16:
3330 divided by 489 is 6 with a remainder of 396.
Put 6 as the next digit of the answer. 
Result so far: 117644.92638036
If we take 2934 away from 3330, we end up with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

The final result is 117644.92638036 with a remainder of 3.96e-07.
