We look at the division of 97970550 by 573 
The aim is to understand the frequency of 573 in 97970550.

Advancing to step 1:
573 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 573

On to step 2:
573 goes into 97 0 times with a remainder of 97.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 97 to get 97.
Bring next digit (9) of the dividend behind the 97 and repeat the process: 979 / 573

Moving on to step 3:
573 goes into 979 1 times with a remainder of 406.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 573 from 979 to get 406.
Grab the next digit (7) from the dividend, add it to 406, then carry on: 4067 / 573

On to step 4:
573 goes into 4067 7 times with a remainder of 56.
The next digit of our result is 7. 
Result so far: 17.0
The remainder is 56 after subtracting 4011 from 4067.
Append the next digit (0) from the dividend to 56 and continue with: 560 / 573

Advancing to step 5:
560 divided by 573 is 0 with a remainder of 560.
Use 0 as the next digit of our solution. 
Result so far: 170.0
Subtract 0 from 560 to get 560.
Append the next digit (5) from the dividend to 560 and continue with: 5605 / 573

Let's proceed to step 6:
573 can be fit into 5605 9 times, resulting in a remainder of 448.
Write down 9 as next digit of the result. 
Result so far: 1709.0
If we subtract 5157 from 5605, we get 448.
Bring next digit (5) of the dividend behind the 448 and repeat the process: 4485 / 573

Step 7:
The number 573 fits into 4485 7 times, leaving a remainder of 474.
The next digit of our result is 7. 
Result so far: 17097.0
Subtract 4011 from 4485 to get 474.
Take the next digit (0) from the dividend and append it to 474, then repeat: 4740 / 573

Step 8:
The number 573 fits into 4740 8 times, leaving a remainder of 156.
Write down 8 as next digit of the result. 
Result so far: 170978.0
If we subtract 4584 from 4740, we get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 9:
The number 573 fits into 1560 2 times, leaving a remainder of 414.
Put 2 as the next digit of the answer. 
Result so far: 170978.2
Subtract 1146 from 1560 to get 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Step 10:
If we divide 4140 by 573, we get 7 and a remainder of 129.
Put 7 as the next digit of the answer. 
Result so far: 170978.27
The remainder is 129 after subtracting 4011 from 4140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Let's proceed to step 11:
573 can be fit into 1290 2 times, resulting in a remainder of 144.
Put 2 as the next digit of the answer. 
Result so far: 170978.272
The remainder is 144 after subtracting 1146 from 1290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 12:
1440 divided by 573 is 2 with a remainder of 294.
Put 2 as the next digit of the answer. 
Result so far: 170978.2722
The remainder is 294 after subtracting 1146 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

The quotient of the division is 170978.2722, and the remainder is 0.00294.
