Let's divide 90049024 by 590
The aim is to understand the frequency of 590 in 90049024.

Going ahead to step 1:
The number 590 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 590

Advancing to step 2:
90 divided by 590 is 0 with a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Grab the next digit (0) from the dividend, add it to 90, then carry on: 900 / 590

Let's proceed to step 3:
The number 590 fits into 900 1 times, leaving a remainder of 310.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 590 from 900, we get 310.
Include the next digit (4) from the dividend after 310, then repeat: 3104 / 590

Step 4:
If we divide 3104 by 590, we get 5 and a remainder of 154.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 154 after subtracting 2950 from 3104.
Bring next digit (9) of the dividend behind the 154 and repeat the process: 1549 / 590

Advancing to step 5:
If we divide 1549 by 590, we get 2 and a remainder of 369.
Record the quotient 2 as the next digit in the result. 
Result so far: 152.0
If we subtract 1180 from 1549, we get 369.
Grab the next digit (0) from the dividend, add it to 369, then carry on: 3690 / 590

Moving on to step 6:
The number 590 fits into 3690 6 times, leaving a remainder of 150.
The number 6 becomes the next digit in our result. 
Result so far: 1526.0
If we take 3540 away from 3690, we end up with 150.
Append the next digit (2) from the dividend to 150 and continue with: 1502 / 590

Advancing to step 7:
The number 590 fits into 1502 2 times, leaving a remainder of 322.
The number 2 becomes the next digit in our result. 
Result so far: 15262.0
Subtract 1180 from 1502 to get 322.
Take the next digit (4) from the dividend and append it to 322, then repeat: 3224 / 590

Advancing to step 8:
590 can be fit into 3224 5 times, resulting in a remainder of 274.
The next digit of our result is 5. 
Result so far: 152625.0
Deduct 2950 from 3224 and we're left with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Let's proceed to step 9:
The number 590 fits into 2740 4 times, leaving a remainder of 380.
Record the quotient 4 as the next digit in the result. 
Result so far: 152625.4
Subtract 2360 from 2740 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 10:
When dividing 3800 by 590, we get 6 with a remainder of 260.
The number 6 becomes the next digit in our result. 
Result so far: 152625.46
If we take 3540 away from 3800, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 11:
590 can be fit into 2600 4 times, resulting in a remainder of 240.
Record the quotient 4 as the next digit in the result. 
Result so far: 152625.464
If we take 2360 away from 2600, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 12:
2400 divided by 590 is 4 with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 152625.4644
If we subtract 2360 from 2400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 152625.4644 with a remainder of 0.0004.
