Let's divide 529737 by 30
The aim is to understand the frequency of 30 in 529737.

On to step 1:
30 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 30

Moving on to step 2:
52 divided by 30 is 1 with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 22 after subtracting 30 from 52.
Fetch the next digit (9) from the dividend, attach it to 22 and continue: 229 / 30

Step 3:
30 can be fit into 229 7 times, resulting in a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we subtract 210 from 229, we get 19.
Include the next digit (7) from the dividend after 19, then repeat: 197 / 30

On to step 4:
The number 30 fits into 197 6 times, leaving a remainder of 17.
Put 6 as the next digit of the answer. 
Result so far: 176.0
If we take 180 away from 197, we end up with 17.
Grab the next digit (3) from the dividend, add it to 17, then carry on: 173 / 30

Going ahead to step 5:
When dividing 173 by 30, we get 5 with a remainder of 23.
Write down 5 as next digit of the result. 
Result so far: 1765.0
Deduct 150 from 173 and we're left with 23.
Append the next digit (7) from the dividend to 23 and continue with: 237 / 30

Moving on to step 6:
The number 30 fits into 237 7 times, leaving a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 17657.0
Deduct 210 from 237 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 7:
30 can be fit into 270 9 times, resulting in a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 17657.9
If we subtract 270 from 270, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 17657.9
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
30 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 17657.9
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 17657.9 with a remainder of 0.0.
