Let's divide 28335576 by 663
The aim is to understand the frequency of 663 in 28335576.

Let's proceed to step 1:
663 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 663

Moving on to step 2:
If we divide 28 by 663, we get 0 and a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Append the next digit (3) from the dividend to 28 and continue with: 283 / 663

Moving on to step 3:
283 divided by 663 is 0 with a remainder of 283.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 283 leaves us with 283.
Append the next digit (3) from the dividend to 283 and continue with: 2833 / 663

Moving on to step 4:
The number 663 fits into 2833 4 times, leaving a remainder of 181.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 2652 from 2833, we get 181.
Grab the next digit (5) from the dividend, add it to 181, then carry on: 1815 / 663

Going ahead to step 5:
When dividing 1815 by 663, we get 2 with a remainder of 489.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Deduct 1326 from 1815 and we're left with 489.
Take the next digit (5) from the dividend and append it to 489, then repeat: 4895 / 663

Let's proceed to step 6:
4895 divided by 663 is 7 with a remainder of 254.
The next digit of our result is 7. 
Result so far: 427.0
If we take 4641 away from 4895, we end up with 254.
Bring next digit (7) of the dividend behind the 254 and repeat the process: 2547 / 663

Advancing to step 7:
If we divide 2547 by 663, we get 3 and a remainder of 558.
Use 3 as the next digit of our solution. 
Result so far: 4273.0
If we take 1989 away from 2547, we end up with 558.
Append the next digit (6) from the dividend to 558 and continue with: 5586 / 663

On to step 8:
5586 divided by 663 is 8 with a remainder of 282.
The number 8 becomes the next digit in our result. 
Result so far: 42738.0
If we take 5304 away from 5586, we end up with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Advancing to step 9:
When dividing 2820 by 663, we get 4 with a remainder of 168.
Use 4 as the next digit of our solution. 
Result so far: 42738.4
If we take 2652 away from 2820, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Advancing to step 10:
663 goes into 1680 2 times with a remainder of 354.
Use 2 as the next digit of our solution. 
Result so far: 42738.42
Subtracting 1326 from 1680 leaves us with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Going ahead to step 11:
663 goes into 3540 5 times with a remainder of 225.
Put 5 as the next digit of the answer. 
Result so far: 42738.425
Subtracting 3315 from 3540 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Going ahead to step 12:
663 goes into 2250 3 times with a remainder of 261.
The next digit of our result is 3. 
Result so far: 42738.4253
If we take 1989 away from 2250, we end up 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.

Going ahead to step 13:
663 can be fit into 2610 3 times, resulting in a remainder of 621.
Record the quotient 3 as the next digit in the result. 
Result so far: 42738.42533
If we take 1989 away from 2610, we end up with 621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6210, and continue the process.

The quotient of the division is 42738.42533, and the remainder is 0.000621.
