We look at the division of 28920660 by 735 
The aim is to understand the frequency of 735 in 28920660.

Step 1:
2 divided by 735 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 735

Moving on to step 2:
When dividing 28 by 735, we get 0 with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Append the next digit (9) from the dividend to 28 and continue with: 289 / 735

On to step 3:
735 goes into 289 0 times with a remainder of 289.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 289 to get 289.
Append the next digit (2) from the dividend to 289 and continue with: 2892 / 735

Advancing to step 4:
2892 divided by 735 is 3 with a remainder of 687.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 2205 from 2892 and we're left with 687.
Grab the next digit (0) from the dividend, add it to 687, then carry on: 6870 / 735

Step 5:
735 can be fit into 6870 9 times, resulting in a remainder of 255.
Use 9 as the next digit of our solution. 
Result so far: 39.0
The remainder is 255 after subtracting 6615 from 6870.
Grab the next digit (6) from the dividend, add it to 255, then carry on: 2556 / 735

Step 6:
2556 divided by 735 is 3 with a remainder of 351.
The number 3 becomes the next digit in our result. 
Result so far: 393.0
Deduct 2205 from 2556 and we're left with 351.
Fetch the next digit (6) from the dividend, attach it to 351 and continue: 3516 / 735

Going ahead to step 7:
When dividing 3516 by 735, we get 4 with a remainder of 576.
Record the quotient 4 as the next digit in the result. 
Result so far: 3934.0
Deduct 2940 from 3516 and we're left with 576.
Bring next digit (0) of the dividend behind the 576 and repeat the process: 5760 / 735

Advancing to step 8:
5760 divided by 735 is 7 with a remainder of 615.
Record the quotient 7 as the next digit in the result. 
Result so far: 39347.0
The remainder is 615 after subtracting 5145 from 5760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Moving on to step 9:
The number 735 fits into 6150 8 times, leaving a remainder of 270.
Put 8 as the next digit of the answer. 
Result so far: 39347.8
If we subtract 5880 from 6150, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 10:
If we divide 2700 by 735, we get 3 and a remainder of 495.
The next digit of our result is 3. 
Result so far: 39347.83
If we take 2205 away from 2700, we end up with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Advancing to step 11:
If we divide 4950 by 735, we get 6 and a remainder of 540.
Record the quotient 6 as the next digit in the result. 
Result so far: 39347.836
Subtract 4410 from 4950 to get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Advancing to step 12:
If we divide 5400 by 735, we get 7 and a remainder of 255.
The next digit of our result is 7. 
Result so far: 39347.8367
Subtract 5145 from 5400 to get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Going ahead to step 13:
The number 735 fits into 2550 3 times, leaving a remainder of 345.
Record the quotient 3 as the next digit in the result. 
Result so far: 39347.83673
Subtract 2205 from 2550 to get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

On to step 14:
735 goes into 3450 4 times with a remainder of 510.
Record the quotient 4 as the next digit in the result. 
Result so far: 39347.836734
Subtract 2940 from 3450 to get 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Moving on to step 15:
735 goes into 5100 6 times with a remainder of 690.
Put 6 as the next digit of the answer. 
Result so far: 39347.8367346
Subtracting 4410 from 5100 leaves us with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Going ahead to step 16:
735 can be fit into 6900 9 times, resulting in a remainder of 285.
Use 9 as the next digit of our solution. 
Result so far: 39347.83673469
If we take 6615 away from 6900, we end up with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

The quotient of the division is 39347.83673469, and the remainder is 2.85e-07.
