4346678 divided by 573 
The aim is to understand the frequency of 573 in 4346678.

On to step 1:
573 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 573

Step 2:
43 divided by 573 is 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Include the next digit (4) from the dividend after 43, then repeat: 434 / 573

Going ahead to step 3:
434 divided by 573 is 0 with a remainder of 434.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 434, we get 434.
Fetch the next digit (6) from the dividend, attach it to 434 and continue: 4346 / 573

Step 4:
The number 573 fits into 4346 7 times, leaving a remainder of 335.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 4011 from 4346, we get 335.
Take the next digit (6) from the dividend and append it to 335, then repeat: 3356 / 573

Advancing to step 5:
573 goes into 3356 5 times with a remainder of 491.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
If we take 2865 away from 3356, we end up with 491.
Take the next digit (7) from the dividend and append it to 491, then repeat: 4917 / 573

Let's proceed to step 6:
573 can be fit into 4917 8 times, resulting in a remainder of 333.
The next digit of our result is 8. 
Result so far: 758.0
If we subtract 4584 from 4917, we get 333.
Take the next digit (8) from the dividend and append it to 333, then repeat: 3338 / 573

On to step 7:
If we divide 3338 by 573, we get 5 and a remainder of 473.
The number 5 becomes the next digit in our result. 
Result so far: 7585.0
The remainder is 473 after subtracting 2865 from 3338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Going ahead to step 8:
If we divide 4730 by 573, we get 8 and a remainder of 146.
Use 8 as the next digit of our solution. 
Result so far: 7585.8
If we take 4584 away from 4730, we end up with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 9:
If we divide 1460 by 573, we get 2 and a remainder of 314.
The number 2 becomes the next digit in our result. 
Result so far: 7585.82
Subtracting 1146 from 1460 leaves us with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Advancing to step 10:
When dividing 3140 by 573, we get 5 with a remainder of 275.
Record the quotient 5 as the next digit in the result. 
Result so far: 7585.825
If we take 2865 away from 3140, we end up with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Moving on to step 11:
573 goes into 2750 4 times with a remainder of 458.
Write down 4 as next digit of the result. 
Result so far: 7585.8254
Subtracting 2292 from 2750 leaves us with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Going ahead to step 12:
When dividing 4580 by 573, we get 7 with a remainder of 569.
Record the quotient 7 as the next digit in the result. 
Result so far: 7585.82547
Subtract 4011 from 4580 to get 569.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

Advancing to step 13:
If we divide 5690 by 573, we get 9 and a remainder of 533.
The number 9 becomes the next digit in our result. 
Result so far: 7585.825479
Deduct 5157 from 5690 and we're left with 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

On to step 14:
If we divide 5330 by 573, we get 9 and a remainder of 173.
Use 9 as the next digit of our solution. 
Result so far: 7585.8254799
If we take 5157 away from 5330, we end up with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

The final result is 7585.8254799 with a remainder of 1.73e-06.
