16185693 divided by 489 
The aim is to understand the frequency of 489 in 16185693.

Step 1:
1 divided by 489 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 489

Moving on to step 2:
489 can be fit into 16 0 times, resulting in a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 489

Going ahead to step 3:
161 divided by 489 is 0 with a remainder of 161.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 161, we get 161.
Fetch the next digit (8) from the dividend, attach it to 161 and continue: 1618 / 489

Going ahead to step 4:
489 can be fit into 1618 3 times, resulting in a remainder of 151.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 1467 from 1618 leaves us with 151.
Bring next digit (5) of the dividend behind the 151 and repeat the process: 1515 / 489

Moving on to step 5:
1515 divided by 489 is 3 with a remainder of 48.
Write down 3 as next digit of the result. 
Result so far: 33.0
If we subtract 1467 from 1515, we get 48.
Fetch the next digit (6) from the dividend, attach it to 48 and continue: 486 / 489

Moving on to step 6:
When dividing 486 by 489, we get 0 with a remainder of 486.
Record the quotient 0 as the next digit in the result. 
Result so far: 330.0
If we subtract 0 from 486, we get 486.
Include the next digit (9) from the dividend after 486, then repeat: 4869 / 489

Going ahead to step 7:
When dividing 4869 by 489, we get 9 with a remainder of 468.
Write down 9 as next digit of the result. 
Result so far: 3309.0
Deduct 4401 from 4869 and we're left with 468.
Include the next digit (3) from the dividend after 468, then repeat: 4683 / 489

Going ahead to step 8:
When dividing 4683 by 489, we get 9 with a remainder of 282.
Use 9 as the next digit of our solution. 
Result so far: 33099.0
If we subtract 4401 from 4683, we get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 9:
The number 489 fits into 2820 5 times, leaving a remainder of 375.
Use 5 as the next digit of our solution. 
Result so far: 33099.5
Deduct 2445 from 2820 and we're left with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

On to step 10:
If we divide 3750 by 489, we get 7 and a remainder of 327.
Write down 7 as next digit of the result. 
Result so far: 33099.57
Deduct 3423 from 3750 and we're left with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Advancing to step 11:
The number 489 fits into 3270 6 times, leaving a remainder of 336.
Write down 6 as next digit of the result. 
Result so far: 33099.576
Deduct 2934 from 3270 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Moving on to step 12:
3360 divided by 489 is 6 with a remainder of 426.
Record the quotient 6 as the next digit in the result. 
Result so far: 33099.5766
The remainder is 426 after subtracting 2934 from 3360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

After the division, we end up with 33099.5766 and a remainder of 0.00426.
