We divide 536086 by 30
The aim is to understand the frequency of 30 in 536086.

Step 1:
30 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 30

Going ahead to step 2:
When dividing 53 by 30, we get 1 with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 30 from 53 and we're left with 23.
Take the next digit (6) from the dividend and append it to 23, then repeat: 236 / 30

Let's proceed to step 3:
The number 30 fits into 236 7 times, leaving a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtract 210 from 236 to get 26.
Take the next digit (0) from the dividend and append it to 26, then repeat: 260 / 30

Going ahead to step 4:
If we divide 260 by 30, we get 8 and a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 178.0
Subtracting 240 from 260 leaves us with 20.
Include the next digit (8) from the dividend after 20, then repeat: 208 / 30

Step 5:
30 goes into 208 6 times with a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 1786.0
If we take 180 away from 208, we end up with 28.
Grab the next digit (6) from the dividend, add it to 28, then carry on: 286 / 30

Step 6:
286 divided by 30 is 9 with a remainder of 16.
Use 9 as the next digit of our solution. 
Result so far: 17869.0
Deduct 270 from 286 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
30 goes into 160 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 17869.5
The remainder is 10 after subtracting 150 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
30 can be fit into 100 3 times, resulting in a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 17869.53
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
When dividing 100 by 30, we get 3 with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 17869.533
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 17869.533 with a remainder of 0.001.
