99576597 ÷ 590 
The aim is to understand the frequency of 590 in 99576597.

Advancing to step 1:
If we divide 9 by 590, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 590

Let's proceed to step 2:
590 goes into 99 0 times with a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Fetch the next digit (5) from the dividend, attach it to 99 and continue: 995 / 590

Let's proceed to step 3:
590 can be fit into 995 1 times, resulting in a remainder of 405.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 590 from 995 and we're left with 405.
Bring next digit (7) of the dividend behind the 405 and repeat the process: 4057 / 590

Going ahead to step 4:
590 can be fit into 4057 6 times, resulting in a remainder of 517.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we take 3540 away from 4057, we end up with 517.
Bring next digit (6) of the dividend behind the 517 and repeat the process: 5176 / 590

Moving on to step 5:
5176 divided by 590 is 8 with a remainder of 456.
The next digit of our result is 8. 
Result so far: 168.0
If we subtract 4720 from 5176, we get 456.
Bring next digit (5) of the dividend behind the 456 and repeat the process: 4565 / 590

Let's proceed to step 6:
When dividing 4565 by 590, we get 7 with a remainder of 435.
The next digit of our result is 7. 
Result so far: 1687.0
Subtracting 4130 from 4565 leaves us with 435.
Grab the next digit (9) from the dividend, add it to 435, then carry on: 4359 / 590

On to step 7:
The number 590 fits into 4359 7 times, leaving a remainder of 229.
Record the quotient 7 as the next digit in the result. 
Result so far: 16877.0
The remainder is 229 after subtracting 4130 from 4359.
Grab the next digit (7) from the dividend, add it to 229, then carry on: 2297 / 590

Going ahead to step 8:
The number 590 fits into 2297 3 times, leaving a remainder of 527.
The next digit of our result is 3. 
Result so far: 168773.0
Subtract 1770 from 2297 to get 527.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5270, and continue the process.

Moving on to step 9:
590 can be fit into 5270 8 times, resulting in a remainder of 550.
Put 8 as the next digit of the answer. 
Result so far: 168773.8
Subtract 4720 from 5270 to get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

On to step 10:
The number 590 fits into 5500 9 times, leaving a remainder of 190.
Write down 9 as next digit of the result. 
Result so far: 168773.89
The remainder is 190 after subtracting 5310 from 5500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 11:
The number 590 fits into 1900 3 times, leaving a remainder of 130.
The next digit of our result is 3. 
Result so far: 168773.893
If we take 1770 away from 1900, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 12:
1300 divided by 590 is 2 with a remainder of 120.
The number 2 becomes the next digit in our result. 
Result so far: 168773.8932
If we subtract 1180 from 1300, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 13:
590 goes into 1200 2 times with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 168773.89322
The remainder is 20 after subtracting 1180 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 168773.89322 with a remainder of 2e-05.
