We look at the division of 33043630 by 663 
The aim is to understand the frequency of 663 in 33043630.

Step 1:
663 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 663

Step 2:
If we divide 33 by 663, we get 0 and a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 33 to get 33.
Take the next digit (0) from the dividend and append it to 33, then repeat: 330 / 663

On to step 3:
663 goes into 330 0 times with a remainder of 330.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 330 and we're left with 330.
Grab the next digit (4) from the dividend, add it to 330, then carry on: 3304 / 663

Advancing to step 4:
When dividing 3304 by 663, we get 4 with a remainder of 652.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 652 after subtracting 2652 from 3304.
Append the next digit (3) from the dividend to 652 and continue with: 6523 / 663

Advancing to step 5:
The number 663 fits into 6523 9 times, leaving a remainder of 556.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
Deduct 5967 from 6523 and we're left with 556.
Fetch the next digit (6) from the dividend, attach it to 556 and continue: 5566 / 663

Going ahead to step 6:
If we divide 5566 by 663, we get 8 and a remainder of 262.
Use 8 as the next digit of our solution. 
Result so far: 498.0
Deduct 5304 from 5566 and we're left with 262.
Take the next digit (3) from the dividend and append it to 262, then repeat: 2623 / 663

Let's proceed to step 7:
2623 divided by 663 is 3 with a remainder of 634.
Put 3 as the next digit of the answer. 
Result so far: 4983.0
Subtracting 1989 from 2623 leaves us with 634.
Fetch the next digit (0) from the dividend, attach it to 634 and continue: 6340 / 663

Moving on to step 8:
663 can be fit into 6340 9 times, resulting in a remainder of 373.
The number 9 becomes the next digit in our result. 
Result so far: 49839.0
The remainder is 373 after subtracting 5967 from 6340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Going ahead to step 9:
663 goes into 3730 5 times with a remainder of 415.
The number 5 becomes the next digit in our result. 
Result so far: 49839.5
Subtract 3315 from 3730 to get 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Advancing to step 10:
4150 divided by 663 is 6 with a remainder of 172.
Put 6 as the next digit of the answer. 
Result so far: 49839.56
If we take 3978 away from 4150, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 11:
When dividing 1720 by 663, we get 2 with a remainder of 394.
The next digit of our result is 2. 
Result so far: 49839.562
Subtract 1326 from 1720 to get 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Let's proceed to step 12:
If we divide 3940 by 663, we get 5 and a remainder of 625.
Write down 5 as next digit of the result. 
Result so far: 49839.5625
The remainder is 625 after subtracting 3315 from 3940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Going ahead to step 13:
6250 divided by 663 is 9 with a remainder of 283.
The next digit of our result is 9. 
Result so far: 49839.56259
Subtracting 5967 from 6250 leaves us with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

On to step 14:
The number 663 fits into 2830 4 times, leaving a remainder of 178.
Use 4 as the next digit of our solution. 
Result so far: 49839.562594
If we take 2652 away from 2830, we end up with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Advancing to step 15:
663 goes into 1780 2 times with a remainder of 454.
Use 2 as the next digit of our solution. 
Result so far: 49839.5625942
Subtract 1326 from 1780 to get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

On to step 16:
The number 663 fits into 4540 6 times, leaving a remainder of 562.
The next digit of our result is 6. 
Result so far: 49839.56259426
The remainder is 562 after subtracting 3978 from 4540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

The quotient of the division is 49839.56259426, and the remainder is 5.62e-07.
