39528492 ÷ 489 
The aim is to understand the frequency of 489 in 39528492.

Let's proceed to step 1:
3 divided by 489 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 489

Advancing to step 2:
The number 489 fits into 39 0 times, leaving a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Bring next digit (5) of the dividend behind the 39 and repeat the process: 395 / 489

Moving on to step 3:
395 divided by 489 is 0 with a remainder of 395.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 395, we get 395.
Bring next digit (2) of the dividend behind the 395 and repeat the process: 3952 / 489

On to step 4:
If we divide 3952 by 489, we get 8 and a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 3912 away from 3952, we end up with 40.
Include the next digit (8) from the dividend after 40, then repeat: 408 / 489

Let's proceed to step 5:
When dividing 408 by 489, we get 0 with a remainder of 408.
Use 0 as the next digit of our solution. 
Result so far: 80.0
Deduct 0 from 408 and we're left with 408.
Take the next digit (4) from the dividend and append it to 408, then repeat: 4084 / 489

Advancing to step 6:
The number 489 fits into 4084 8 times, leaving a remainder of 172.
Use 8 as the next digit of our solution. 
Result so far: 808.0
Subtract 3912 from 4084 to get 172.
Grab the next digit (9) from the dividend, add it to 172, then carry on: 1729 / 489

On to step 7:
When dividing 1729 by 489, we get 3 with a remainder of 262.
Write down 3 as next digit of the result. 
Result so far: 8083.0
Subtracting 1467 from 1729 leaves us with 262.
Take the next digit (2) from the dividend and append it to 262, then repeat: 2622 / 489

On to step 8:
489 goes into 2622 5 times with a remainder of 177.
The number 5 becomes the next digit in our result. 
Result so far: 80835.0
If we subtract 2445 from 2622, we get 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 9:
489 can be fit into 1770 3 times, resulting in a remainder of 303.
Put 3 as the next digit of the answer. 
Result so far: 80835.3
Deduct 1467 from 1770 and we're left 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.

On to step 10:
If we divide 3030 by 489, we get 6 and a remainder of 96.
Record the quotient 6 as the next digit in the result. 
Result so far: 80835.36
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.

Moving on to step 11:
The number 489 fits into 960 1 times, leaving a remainder of 471.
The number 1 becomes the next digit in our result. 
Result so far: 80835.361
If we take 489 away from 960, we end up with 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

On to step 12:
489 can be fit into 4710 9 times, resulting in a remainder of 309.
Record the quotient 9 as the next digit in the result. 
Result so far: 80835.3619
If we subtract 4401 from 4710, we get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Going ahead to step 13:
The number 489 fits into 3090 6 times, leaving a remainder of 156.
Put 6 as the next digit of the answer. 
Result so far: 80835.36196
If we subtract 2934 from 3090, we get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 14:
When dividing 1560 by 489, we get 3 with a remainder of 93.
Put 3 as the next digit of the answer. 
Result so far: 80835.361963
Deduct 1467 from 1560 and we're left with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Let's proceed to step 15:
489 goes into 930 1 times with a remainder of 441.
Use 1 as the next digit of our solution. 
Result so far: 80835.3619631
Subtracting 489 from 930 leaves us with 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Step 16:
The number 489 fits into 4410 9 times, leaving a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 80835.36196319
Subtract 4401 from 4410 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final outcome is 80835.36196319, with a leftover of 9e-09.
