We look at the division of 90369024 by 587 
The aim is to understand the frequency of 587 in 90369024.

Moving on to step 1:
If we divide 9 by 587, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 587

Going ahead to step 2:
If we divide 90 by 587, we get 0 and a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Grab the next digit (3) from the dividend, add it to 90, then carry on: 903 / 587

On to step 3:
When dividing 903 by 587, we get 1 with a remainder of 316.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 587 from 903 leaves us with 316.
Grab the next digit (6) from the dividend, add it to 316, then carry on: 3166 / 587

Moving on to step 4:
587 goes into 3166 5 times with a remainder of 231.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtract 2935 from 3166 to get 231.
Append the next digit (9) from the dividend to 231 and continue with: 2319 / 587

Moving on to step 5:
When dividing 2319 by 587, we get 3 with a remainder of 558.
Record the quotient 3 as the next digit in the result. 
Result so far: 153.0
Subtracting 1761 from 2319 leaves us with 558.
Bring next digit (0) of the dividend behind the 558 and repeat the process: 5580 / 587

Step 6:
587 can be fit into 5580 9 times, resulting in a remainder of 297.
Put 9 as the next digit of the answer. 
Result so far: 1539.0
Subtracting 5283 from 5580 leaves us with 297.
Include the next digit (2) from the dividend after 297, then repeat: 2972 / 587

Step 7:
587 goes into 2972 5 times with a remainder of 37.
Write down 5 as next digit of the result. 
Result so far: 15395.0
Deduct 2935 from 2972 and we're left with 37.
Take the next digit (4) from the dividend and append it to 37, then repeat: 374 / 587

On to step 8:
If we divide 374 by 587, we get 0 and a remainder of 374.
The next digit of our result is 0. 
Result so far: 153950.0
If we subtract 0 from 374, we get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Moving on to step 9:
If we divide 3740 by 587, we get 6 and a remainder of 218.
The number 6 becomes the next digit in our result. 
Result so far: 153950.6
Subtract 3522 from 3740 to get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

On to step 10:
587 goes into 2180 3 times with a remainder of 419.
The next digit of our result is 3. 
Result so far: 153950.63
Deduct 1761 from 2180 and we're left with 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Moving on to step 11:
If we divide 4190 by 587, we get 7 and a remainder of 81.
Record the quotient 7 as the next digit in the result. 
Result so far: 153950.637
Subtracting 4109 from 4190 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 12:
The number 587 fits into 810 1 times, leaving a remainder of 223.
Record the quotient 1 as the next digit in the result. 
Result so far: 153950.6371
Deduct 587 from 810 and we're left with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Advancing to step 13:
587 goes into 2230 3 times with a remainder of 469.
Write down 3 as next digit of the result. 
Result so far: 153950.63713
The remainder is 469 after subtracting 1761 from 2230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

Moving on to step 14:
587 can be fit into 4690 7 times, resulting in a remainder of 581.
Use 7 as the next digit of our solution. 
Result so far: 153950.637137
If we subtract 4109 from 4690, we get 581.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

Moving on to step 15:
5810 divided by 587 is 9 with a remainder of 527.
Put 9 as the next digit of the answer. 
Result so far: 153950.6371379
Subtract 5283 from 5810 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.

Let's proceed to step 16:
If we divide 5270 by 587, we get 8 and a remainder of 574.
The next digit of our result is 8. 
Result so far: 153950.63713798
Deduct 4696 from 5270 and we're left with 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

In conclusion, the division gives 153950.63713798 with a balance of 5.74e-07.
