We're dividing 18537525 by 599 
The aim is to understand the frequency of 599 in 18537525.

Going ahead to step 1:
If we divide 1 by 599, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 599

Moving on to step 2:
When dividing 18 by 599, we get 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 599

Let's proceed to step 3:
599 can be fit into 185 0 times, resulting in a remainder of 185.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 185 and we're left with 185.
Bring next digit (3) of the dividend behind the 185 and repeat the process: 1853 / 599

Moving on to step 4:
1853 divided by 599 is 3 with a remainder of 56.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 1797 from 1853, we get 56.
Take the next digit (7) from the dividend and append it to 56, then repeat: 567 / 599

Advancing to step 5:
If we divide 567 by 599, we get 0 and a remainder of 567.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
Subtract 0 from 567 to get 567.
Take the next digit (5) from the dividend and append it to 567, then repeat: 5675 / 599

Moving on to step 6:
If we divide 5675 by 599, we get 9 and a remainder of 284.
Put 9 as the next digit of the answer. 
Result so far: 309.0
Subtract 5391 from 5675 to get 284.
Bring next digit (2) of the dividend behind the 284 and repeat the process: 2842 / 599

Let's proceed to step 7:
If we divide 2842 by 599, we get 4 and a remainder of 446.
The number 4 becomes the next digit in our result. 
Result so far: 3094.0
The remainder is 446 after subtracting 2396 from 2842.
Grab the next digit (5) from the dividend, add it to 446, then carry on: 4465 / 599

Going ahead to step 8:
599 can be fit into 4465 7 times, resulting in a remainder of 272.
The next digit of our result is 7. 
Result so far: 30947.0
If we subtract 4193 from 4465, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Step 9:
The number 599 fits into 2720 4 times, leaving a remainder of 324.
Write down 4 as next digit of the result. 
Result so far: 30947.4
Subtracting 2396 from 2720 leaves us with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Step 10:
599 goes into 3240 5 times with a remainder of 245.
The number 5 becomes the next digit in our result. 
Result so far: 30947.45
The remainder is 245 after subtracting 2995 from 3240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

On to step 11:
599 can be fit into 2450 4 times, resulting in a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 30947.454
If we take 2396 away from 2450, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 12:
599 can be fit into 540 0 times, resulting in a remainder of 540.
Record the quotient 0 as the next digit in the result. 
Result so far: 30947.454
If we take 0 away from 540, we end up with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Going ahead to step 13:
5400 divided by 599 is 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 30947.45409
Deduct 5391 from 5400 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 14:
90 divided by 599 is 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 30947.45409
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 15:
900 divided by 599 is 1 with a remainder of 301.
The next digit of our result is 1. 
Result so far: 30947.4540901
If we subtract 599 from 900, we get 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Moving on to step 16:
When dividing 3010 by 599, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 30947.45409015
The remainder is 15 after subtracting 2995 from 3010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

In conclusion, the division gives 30947.45409015 with a balance of 1.5e-08.
