We're dividing 52513261 by 573 
The aim is to understand the frequency of 573 in 52513261.

Step 1:
When dividing 5 by 573, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 573

Let's proceed to step 2:
If we divide 52 by 573, we get 0 and a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Grab the next digit (5) from the dividend, add it to 52, then carry on: 525 / 573

Step 3:
573 goes into 525 0 times with a remainder of 525.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 525 and we're left with 525.
Include the next digit (1) from the dividend after 525, then repeat: 5251 / 573

Advancing to step 4:
5251 divided by 573 is 9 with a remainder of 94.
The next digit of our result is 9. 
Result so far: 9.0
If we take 5157 away from 5251, we end up with 94.
Fetch the next digit (3) from the dividend, attach it to 94 and continue: 943 / 573

Let's proceed to step 5:
573 goes into 943 1 times with a remainder of 370.
Write down 1 as next digit of the result. 
Result so far: 91.0
Subtracting 573 from 943 leaves us with 370.
Fetch the next digit (2) from the dividend, attach it to 370 and continue: 3702 / 573

Advancing to step 6:
573 can be fit into 3702 6 times, resulting in a remainder of 264.
Write down 6 as next digit of the result. 
Result so far: 916.0
If we subtract 3438 from 3702, we get 264.
Bring next digit (6) of the dividend behind the 264 and repeat the process: 2646 / 573

On to step 7:
2646 divided by 573 is 4 with a remainder of 354.
The next digit of our result is 4. 
Result so far: 9164.0
If we take 2292 away from 2646, we end up with 354.
Take the next digit (1) from the dividend and append it to 354, then repeat: 3541 / 573

On to step 8:
The number 573 fits into 3541 6 times, leaving a remainder of 103.
Record the quotient 6 as the next digit in the result. 
Result so far: 91646.0
If we take 3438 away from 3541, we end up with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

On to step 9:
573 can be fit into 1030 1 times, resulting in a remainder of 457.
Put 1 as the next digit of the answer. 
Result so far: 91646.1
Subtract 573 from 1030 to get 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Advancing to step 10:
The number 573 fits into 4570 7 times, leaving a remainder of 559.
Use 7 as the next digit of our solution. 
Result so far: 91646.17
If we take 4011 away from 4570, we end up with 559.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

Moving on to step 11:
573 goes into 5590 9 times with a remainder of 433.
Use 9 as the next digit of our solution. 
Result so far: 91646.179
Subtracting 5157 from 5590 leaves us with 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Moving on to step 12:
573 can be fit into 4330 7 times, resulting in a remainder of 319.
Record the quotient 7 as the next digit in the result. 
Result so far: 91646.1797
Subtract 4011 from 4330 to get 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Going ahead to step 13:
573 can be fit into 3190 5 times, resulting in a remainder of 325.
Write down 5 as next digit of the result. 
Result so far: 91646.17975
Subtract 2865 from 3190 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Step 14:
If we divide 3250 by 573, we get 5 and a remainder of 385.
The number 5 becomes the next digit in our result. 
Result so far: 91646.179755
Subtracting 2865 from 3250 leaves us with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

In conclusion, the division gives 91646.179755 with a balance of 3.85e-05.
