We're dividing 99637471 by 576 
The aim is to understand the frequency of 576 in 99637471.

Moving on to step 1:
If we divide 9 by 576, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 576

Going ahead to step 2:
If we divide 99 by 576, we get 0 and a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Include the next digit (6) from the dividend after 99, then repeat: 996 / 576

Step 3:
576 goes into 996 1 times with a remainder of 420.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 420 after subtracting 576 from 996.
Fetch the next digit (3) from the dividend, attach it to 420 and continue: 4203 / 576

On to step 4:
The number 576 fits into 4203 7 times, leaving a remainder of 171.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtract 4032 from 4203 to get 171.
Grab the next digit (7) from the dividend, add it to 171, then carry on: 1717 / 576

Moving on to step 5:
The number 576 fits into 1717 2 times, leaving a remainder of 565.
Use 2 as the next digit of our solution. 
Result so far: 172.0
Subtract 1152 from 1717 to get 565.
Include the next digit (4) from the dividend after 565, then repeat: 5654 / 576

Going ahead to step 6:
576 can be fit into 5654 9 times, resulting in a remainder of 470.
Use 9 as the next digit of our solution. 
Result so far: 1729.0
Subtracting 5184 from 5654 leaves us with 470.
Take the next digit (7) from the dividend and append it to 470, then repeat: 4707 / 576

Advancing to step 7:
4707 divided by 576 is 8 with a remainder of 99.
Put 8 as the next digit of the answer. 
Result so far: 17298.0
Deduct 4608 from 4707 and we're left with 99.
Append the next digit (1) from the dividend to 99 and continue with: 991 / 576

On to step 8:
If we divide 991 by 576, we get 1 and a remainder of 415.
Write down 1 as next digit of the result. 
Result so far: 172981.0
Subtracting 576 from 991 leaves us with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Let's proceed to step 9:
The number 576 fits into 4150 7 times, leaving a remainder of 118.
The next digit of our result is 7. 
Result so far: 172981.7
Subtracting 4032 from 4150 leaves us with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Step 10:
1180 divided by 576 is 2 with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 172981.72
Subtract 1152 from 1180 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 11:
576 goes into 280 0 times with a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 172981.72
If we subtract 0 from 280, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 12:
576 goes into 2800 4 times with a remainder of 496.
Write down 4 as next digit of the result. 
Result so far: 172981.7204
The remainder is 496 after subtracting 2304 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Step 13:
4960 divided by 576 is 8 with a remainder of 352.
Put 8 as the next digit of the answer. 
Result so far: 172981.72048
The remainder is 352 after subtracting 4608 from 4960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 14:
3520 divided by 576 is 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 172981.720486
Subtract 3456 from 3520 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 15:
When dividing 640 by 576, we get 1 with a remainder of 64.
The next digit of our result is 1. 
Result so far: 172981.7204861
Subtract 576 from 640 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 16:
If we divide 640 by 576, we get 1 and a remainder of 64.
Record the quotient 1 as the next digit in the result. 
Result so far: 172981.72048611
Subtracting 576 from 640 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 172981.72048611 with a remainder of 6.4e-08.
