Let's divide 78210259 by 568
The aim is to understand the frequency of 568 in 78210259.

Step 1:
7 divided by 568 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 568

Advancing to step 2:
568 goes into 78 0 times with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Append the next digit (2) from the dividend to 78 and continue with: 782 / 568

Let's proceed to step 3:
782 divided by 568 is 1 with a remainder of 214.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 568 from 782 to get 214.
Include the next digit (1) from the dividend after 214, then repeat: 2141 / 568

Going ahead to step 4:
The number 568 fits into 2141 3 times, leaving a remainder of 437.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 1704 from 2141 leaves us with 437.
Take the next digit (0) from the dividend and append it to 437, then repeat: 4370 / 568

Let's proceed to step 5:
The number 568 fits into 4370 7 times, leaving a remainder of 394.
Write down 7 as next digit of the result. 
Result so far: 137.0
If we take 3976 away from 4370, we end up with 394.
Include the next digit (2) from the dividend after 394, then repeat: 3942 / 568

On to step 6:
The number 568 fits into 3942 6 times, leaving a remainder of 534.
The number 6 becomes the next digit in our result. 
Result so far: 1376.0
Subtracting 3408 from 3942 leaves us with 534.
Append the next digit (5) from the dividend to 534 and continue with: 5345 / 568

Advancing to step 7:
5345 divided by 568 is 9 with a remainder of 233.
Use 9 as the next digit of our solution. 
Result so far: 13769.0
Deduct 5112 from 5345 and we're left with 233.
Fetch the next digit (9) from the dividend, attach it to 233 and continue: 2339 / 568

Step 8:
568 can be fit into 2339 4 times, resulting in a remainder of 67.
Use 4 as the next digit of our solution. 
Result so far: 137694.0
If we subtract 2272 from 2339, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 9:
670 divided by 568 is 1 with a remainder of 102.
Write down 1 as next digit of the result. 
Result so far: 137694.1
If we take 568 away from 670, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Going ahead to step 10:
568 goes into 1020 1 times with a remainder of 452.
The number 1 becomes the next digit in our result. 
Result so far: 137694.11
If we subtract 568 from 1020, we get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

After the division, we end up with 137694.11 and a remainder of 0.452.
