We divide 90584598 by 574
The aim is to understand the frequency of 574 in 90584598.

Advancing to step 1:
If we divide 9 by 574, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 574

Step 2:
When dividing 90 by 574, we get 0 with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Grab the next digit (5) from the dividend, add it to 90, then carry on: 905 / 574

Advancing to step 3:
If we divide 905 by 574, we get 1 and a remainder of 331.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 574 from 905 leaves us with 331.
Bring next digit (8) of the dividend behind the 331 and repeat the process: 3318 / 574

On to step 4:
If we divide 3318 by 574, we get 5 and a remainder of 448.
Use 5 as the next digit of our solution. 
Result so far: 15.0
The remainder is 448 after subtracting 2870 from 3318.
Include the next digit (4) from the dividend after 448, then repeat: 4484 / 574

Going ahead to step 5:
When dividing 4484 by 574, we get 7 with a remainder of 466.
Use 7 as the next digit of our solution. 
Result so far: 157.0
Deduct 4018 from 4484 and we're left with 466.
Bring next digit (5) of the dividend behind the 466 and repeat the process: 4665 / 574

Going ahead to step 6:
574 can be fit into 4665 8 times, resulting in a remainder of 73.
Record the quotient 8 as the next digit in the result. 
Result so far: 1578.0
Subtract 4592 from 4665 to get 73.
Grab the next digit (9) from the dividend, add it to 73, then carry on: 739 / 574

Moving on to step 7:
When dividing 739 by 574, we get 1 with a remainder of 165.
The next digit of our result is 1. 
Result so far: 15781.0
Subtracting 574 from 739 leaves us with 165.
Grab the next digit (8) from the dividend, add it to 165, then carry on: 1658 / 574

Let's proceed to step 8:
If we divide 1658 by 574, we get 2 and a remainder of 510.
Write down 2 as next digit of the result. 
Result so far: 157812.0
If we subtract 1148 from 1658, we get 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Moving on to step 9:
574 can be fit into 5100 8 times, resulting in a remainder of 508.
The number 8 becomes the next digit in our result. 
Result so far: 157812.8
The remainder is 508 after subtracting 4592 from 5100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Let's proceed to step 10:
The number 574 fits into 5080 8 times, leaving a remainder of 488.
Use 8 as the next digit of our solution. 
Result so far: 157812.88
The remainder is 488 after subtracting 4592 from 5080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

The final result is 157812.88 with a remainder of 0.488.
