Let's divide 78253311 by 572
The aim is to understand the frequency of 572 in 78253311.

Going ahead to step 1:
7 divided by 572 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 572

Advancing to step 2:
572 goes into 78 0 times with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Take the next digit (2) from the dividend and append it to 78, then repeat: 782 / 572

Step 3:
782 divided by 572 is 1 with a remainder of 210.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 210 after subtracting 572 from 782.
Grab the next digit (5) from the dividend, add it to 210, then carry on: 2105 / 572

Step 4:
572 goes into 2105 3 times with a remainder of 389.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 1716 from 2105 to get 389.
Take the next digit (3) from the dividend and append it to 389, then repeat: 3893 / 572

Advancing to step 5:
572 can be fit into 3893 6 times, resulting in a remainder of 461.
Use 6 as the next digit of our solution. 
Result so far: 136.0
The remainder is 461 after subtracting 3432 from 3893.
Include the next digit (3) from the dividend after 461, then repeat: 4613 / 572

Step 6:
572 goes into 4613 8 times with a remainder of 37.
The number 8 becomes the next digit in our result. 
Result so far: 1368.0
Deduct 4576 from 4613 and we're left with 37.
Take the next digit (1) from the dividend and append it to 37, then repeat: 371 / 572

On to step 7:
If we divide 371 by 572, we get 0 and a remainder of 371.
The next digit of our result is 0. 
Result so far: 13680.0
Subtracting 0 from 371 leaves us with 371.
Bring next digit (1) of the dividend behind the 371 and repeat the process: 3711 / 572

Let's proceed to step 8:
The number 572 fits into 3711 6 times, leaving a remainder of 279.
Put 6 as the next digit of the answer. 
Result so far: 136806.0
Subtract 3432 from 3711 to get 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Going ahead to step 9:
The number 572 fits into 2790 4 times, leaving a remainder of 502.
The next digit of our result is 4. 
Result so far: 136806.4
Subtract 2288 from 2790 to get 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

On to step 10:
The number 572 fits into 5020 8 times, leaving a remainder of 444.
The number 8 becomes the next digit in our result. 
Result so far: 136806.48
If we take 4576 away from 5020, we end up with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Moving on to step 11:
When dividing 4440 by 572, we get 7 with a remainder of 436.
Put 7 as the next digit of the answer. 
Result so far: 136806.487
Subtracting 4004 from 4440 leaves us with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Step 12:
When dividing 4360 by 572, we get 7 with a remainder of 356.
The number 7 becomes the next digit in our result. 
Result so far: 136806.4877
If we take 4004 away from 4360, we end up with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

The final result is 136806.4877 with a remainder of 0.00356.
