Let's divide 33291437 by 513
The aim is to understand the frequency of 513 in 33291437.

Going ahead to step 1:
3 divided by 513 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 513

Moving on to step 2:
33 divided by 513 is 0 with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 33 and we're left with 33.
Grab the next digit (2) from the dividend, add it to 33, then carry on: 332 / 513

Advancing to step 3:
When dividing 332 by 513, we get 0 with a remainder of 332.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 332, we get 332.
Fetch the next digit (9) from the dividend, attach it to 332 and continue: 3329 / 513

Going ahead to step 4:
513 goes into 3329 6 times with a remainder of 251.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 3078 from 3329 leaves us with 251.
Bring next digit (1) of the dividend behind the 251 and repeat the process: 2511 / 513

Going ahead to step 5:
When dividing 2511 by 513, we get 4 with a remainder of 459.
Put 4 as the next digit of the answer. 
Result so far: 64.0
The remainder is 459 after subtracting 2052 from 2511.
Fetch the next digit (4) from the dividend, attach it to 459 and continue: 4594 / 513

Let's proceed to step 6:
513 goes into 4594 8 times with a remainder of 490.
The number 8 becomes the next digit in our result. 
Result so far: 648.0
Deduct 4104 from 4594 and we're left with 490.
Include the next digit (3) from the dividend after 490, then repeat: 4903 / 513

Moving on to step 7:
If we divide 4903 by 513, we get 9 and a remainder of 286.
The next digit of our result is 9. 
Result so far: 6489.0
Deduct 4617 from 4903 and we're left with 286.
Take the next digit (7) from the dividend and append it to 286, then repeat: 2867 / 513

Advancing to step 8:
When dividing 2867 by 513, we get 5 with a remainder of 302.
Use 5 as the next digit of our solution. 
Result so far: 64895.0
Deduct 2565 from 2867 and we're left with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Advancing to step 9:
513 can be fit into 3020 5 times, resulting in a remainder of 455.
Record the quotient 5 as the next digit in the result. 
Result so far: 64895.5
Subtract 2565 from 3020 to get 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Advancing to step 10:
The number 513 fits into 4550 8 times, leaving a remainder of 446.
The number 8 becomes the next digit in our result. 
Result so far: 64895.58
If we subtract 4104 from 4550, we get 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

On to step 11:
513 goes into 4460 8 times with a remainder of 356.
The number 8 becomes the next digit in our result. 
Result so far: 64895.588
The remainder is 356 after subtracting 4104 from 4460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

After the division, we end up with 64895.588 and a remainder of 0.0356.
