We're dividing 31564467 by 573 
The aim is to understand the frequency of 573 in 31564467.

Advancing to step 1:
If we divide 3 by 573, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 573

Step 2:
If we divide 31 by 573, we get 0 and a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Take the next digit (5) from the dividend and append it to 31, then repeat: 315 / 573

Let's proceed to step 3:
When dividing 315 by 573, we get 0 with a remainder of 315.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 315 and we're left with 315.
Grab the next digit (6) from the dividend, add it to 315, then carry on: 3156 / 573

Advancing to step 4:
The number 573 fits into 3156 5 times, leaving a remainder of 291.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 2865 from 3156 and we're left with 291.
Grab the next digit (4) from the dividend, add it to 291, then carry on: 2914 / 573

Step 5:
573 can be fit into 2914 5 times, resulting in a remainder of 49.
Write down 5 as next digit of the result. 
Result so far: 55.0
Subtracting 2865 from 2914 leaves us with 49.
Fetch the next digit (4) from the dividend, attach it to 49 and continue: 494 / 573

Moving on to step 6:
494 divided by 573 is 0 with a remainder of 494.
Use 0 as the next digit of our solution. 
Result so far: 550.0
If we subtract 0 from 494, we get 494.
Include the next digit (6) from the dividend after 494, then repeat: 4946 / 573

Step 7:
573 goes into 4946 8 times with a remainder of 362.
The next digit of our result is 8. 
Result so far: 5508.0
Deduct 4584 from 4946 and we're left with 362.
Grab the next digit (7) from the dividend, add it to 362, then carry on: 3627 / 573

Advancing to step 8:
573 can be fit into 3627 6 times, resulting in a remainder of 189.
Use 6 as the next digit of our solution. 
Result so far: 55086.0
Subtracting 3438 from 3627 leaves us with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Let's proceed to step 9:
The number 573 fits into 1890 3 times, leaving a remainder of 171.
Put 3 as the next digit of the answer. 
Result so far: 55086.3
If we subtract 1719 from 1890, we get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Advancing to step 10:
When dividing 1710 by 573, we get 2 with a remainder of 564.
Record the quotient 2 as the next digit in the result. 
Result so far: 55086.32
Subtract 1146 from 1710 to get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

On to step 11:
The number 573 fits into 5640 9 times, leaving a remainder of 483.
Record the quotient 9 as the next digit in the result. 
Result so far: 55086.329
If we subtract 5157 from 5640, we get 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

Moving on to step 12:
When dividing 4830 by 573, we get 8 with a remainder of 246.
Put 8 as the next digit of the answer. 
Result so far: 55086.3298
The remainder is 246 after subtracting 4584 from 4830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Moving on to step 13:
573 goes into 2460 4 times with a remainder of 168.
The number 4 becomes the next digit in our result. 
Result so far: 55086.32984
Subtracting 2292 from 2460 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 14:
If we divide 1680 by 573, we get 2 and a remainder of 534.
The number 2 becomes the next digit in our result. 
Result so far: 55086.329842
Subtract 1146 from 1680 to get 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Let's proceed to step 15:
When dividing 5340 by 573, we get 9 with a remainder of 183.
The next digit of our result is 9. 
Result so far: 55086.3298429
Deduct 5157 from 5340 and we're left with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Moving on to step 16:
573 goes into 1830 3 times with a remainder of 111.
The next digit of our result is 3. 
Result so far: 55086.32984293
If we subtract 1719 from 1830, we get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

In conclusion, the division gives 55086.32984293 with a balance of 1.11e-07.
