91533237 divided by 489 
The aim is to understand the frequency of 489 in 91533237.

Let's proceed to step 1:
489 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 489

Step 2:
489 goes into 91 0 times with a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Take the next digit (5) from the dividend and append it to 91, then repeat: 915 / 489

Moving on to step 3:
The number 489 fits into 915 1 times, leaving a remainder of 426.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 489 from 915, we get 426.
Bring next digit (3) of the dividend behind the 426 and repeat the process: 4263 / 489

Let's proceed to step 4:
If we divide 4263 by 489, we get 8 and a remainder of 351.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we subtract 3912 from 4263, we get 351.
Include the next digit (3) from the dividend after 351, then repeat: 3513 / 489

Moving on to step 5:
If we divide 3513 by 489, we get 7 and a remainder of 90.
Write down 7 as next digit of the result. 
Result so far: 187.0
Subtracting 3423 from 3513 leaves us with 90.
Bring next digit (2) of the dividend behind the 90 and repeat the process: 902 / 489

Going ahead to step 6:
489 goes into 902 1 times with a remainder of 413.
The next digit of our result is 1. 
Result so far: 1871.0
If we subtract 489 from 902, we get 413.
Bring next digit (3) of the dividend behind the 413 and repeat the process: 4133 / 489

Advancing to step 7:
4133 divided by 489 is 8 with a remainder of 221.
Record the quotient 8 as the next digit in the result. 
Result so far: 18718.0
Subtract 3912 from 4133 to get 221.
Append the next digit (7) from the dividend to 221 and continue with: 2217 / 489

Step 8:
489 goes into 2217 4 times with a remainder of 261.
Record the quotient 4 as the next digit in the result. 
Result so far: 187184.0
Subtracting 1956 from 2217 leaves us with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Advancing to step 9:
If we divide 2610 by 489, we get 5 and a remainder of 165.
The next digit of our result is 5. 
Result so far: 187184.5
Deduct 2445 from 2610 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 10:
The number 489 fits into 1650 3 times, leaving a remainder of 183.
The next digit of our result is 3. 
Result so far: 187184.53
If we subtract 1467 from 1650, we get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Advancing to step 11:
When dividing 1830 by 489, we get 3 with a remainder of 363.
Use 3 as the next digit of our solution. 
Result so far: 187184.533
Deduct 1467 from 1830 and we're left with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

The quotient of the division is 187184.533, and the remainder is 0.0363.
