90321043 divided by 489 
The aim is to understand the frequency of 489 in 90321043.

Advancing to step 1:
9 divided by 489 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 489

Going ahead to step 2:
When dividing 90 by 489, we get 0 with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Append the next digit (3) from the dividend to 90 and continue with: 903 / 489

Let's proceed to step 3:
903 divided by 489 is 1 with a remainder of 414.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 414 after subtracting 489 from 903.
Bring next digit (2) of the dividend behind the 414 and repeat the process: 4142 / 489

Advancing to step 4:
The number 489 fits into 4142 8 times, leaving a remainder of 230.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
The remainder is 230 after subtracting 3912 from 4142.
Fetch the next digit (1) from the dividend, attach it to 230 and continue: 2301 / 489

Going ahead to step 5:
If we divide 2301 by 489, we get 4 and a remainder of 345.
Put 4 as the next digit of the answer. 
Result so far: 184.0
The remainder is 345 after subtracting 1956 from 2301.
Include the next digit (0) from the dividend after 345, then repeat: 3450 / 489

Let's proceed to step 6:
3450 divided by 489 is 7 with a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 1847.0
If we subtract 3423 from 3450, we get 27.
Include the next digit (4) from the dividend after 27, then repeat: 274 / 489

On to step 7:
489 goes into 274 0 times with a remainder of 274.
Put 0 as the next digit of the answer. 
Result so far: 18470.0
Subtract 0 from 274 to get 274.
Grab the next digit (3) from the dividend, add it to 274, then carry on: 2743 / 489

Going ahead to step 8:
When dividing 2743 by 489, we get 5 with a remainder of 298.
Write down 5 as next digit of the result. 
Result so far: 184705.0
The remainder is 298 after subtracting 2445 from 2743.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Going ahead to step 9:
If we divide 2980 by 489, we get 6 and a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 184705.6
If we subtract 2934 from 2980, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 10:
460 divided by 489 is 0 with a remainder of 460.
Put 0 as the next digit of the answer. 
Result so far: 184705.6
If we subtract 0 from 460, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Advancing to step 11:
489 goes into 4600 9 times with a remainder of 199.
Put 9 as the next digit of the answer. 
Result so far: 184705.609
If we subtract 4401 from 4600, we get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

On to step 12:
When dividing 1990 by 489, we get 4 with a remainder of 34.
The next digit of our result is 4. 
Result so far: 184705.6094
Deduct 1956 from 1990 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 13:
If we divide 340 by 489, we get 0 and a remainder of 340.
Write down 0 as next digit of the result. 
Result so far: 184705.6094
If we take 0 away from 340, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 14:
489 can be fit into 3400 6 times, resulting in a remainder of 466.
Put 6 as the next digit of the answer. 
Result so far: 184705.609406
If we subtract 2934 from 3400, we get 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Going ahead to step 15:
The number 489 fits into 4660 9 times, leaving a remainder of 259.
Record the quotient 9 as the next digit in the result. 
Result so far: 184705.6094069
Subtract 4401 from 4660 to get 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Moving on to step 16:
When dividing 2590 by 489, we get 5 with a remainder of 145.
Write down 5 as next digit of the result. 
Result so far: 184705.60940695
Subtracting 2445 from 2590 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

The final result is 184705.60940695 with a remainder of 1.45e-07.
