We divide 513058 by 30
The aim is to understand the frequency of 30 in 513058.

Step 1:
When dividing 5 by 30, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 30

Going ahead to step 2:
If we divide 51 by 30, we get 1 and a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 30 from 51, we get 21.
Take the next digit (3) from the dividend and append it to 21, then repeat: 213 / 30

Let's proceed to step 3:
30 goes into 213 7 times with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we subtract 210 from 213, we get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 30

Going ahead to step 4:
30 can be fit into 30 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 171.0
If we subtract 30 from 30, we get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 30

Advancing to step 5:
If we divide 5 by 30, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 1710.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 30

Moving on to step 6:
When dividing 58 by 30, we get 1 with a remainder of 28.
The next digit of our result is 1. 
Result so far: 17101.0
Subtract 30 from 58 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 7:
If we divide 280 by 30, we get 9 and a remainder of 10.
The next digit of our result is 9. 
Result so far: 17101.9
If we take 270 away from 280, we end up 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.

Step 8:
The number 30 fits into 100 3 times, leaving a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 17101.93
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.

Moving on to step 9:
The number 30 fits into 100 3 times, leaving a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 17101.933
If we take 90 away from 100, we end up 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.

The final result is 17101.933 with a remainder of 0.001.
