We're dividing 526401 by 30 
The aim is to understand the frequency of 30 in 526401.

Going ahead 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
Subtracting 0 from 5 leaves us with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 30

On to step 2:
52 divided by 30 is 1 with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 30 away from 52, we end up with 22.
Take the next digit (6) from the dividend and append it to 22, then repeat: 226 / 30

Going ahead to step 3:
The number 30 fits into 226 7 times, leaving a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
The remainder is 16 after subtracting 210 from 226.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 30

Step 4:
The number 30 fits into 164 5 times, leaving a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 175.0
Subtract 150 from 164 to get 14.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 30

Step 5:
30 goes into 140 4 times with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 1754.0
If we subtract 120 from 140, we get 20.
Include the next digit (1) from the dividend after 20, then repeat: 201 / 30

Going ahead to step 6:
30 can be fit into 201 6 times, resulting in a remainder of 21.
Put 6 as the next digit of the answer. 
Result so far: 17546.0
If we subtract 180 from 201, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
If we divide 210 by 30, we get 7 and a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 17546.7
Subtract 210 from 210 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.

Advancing to step 8:
30 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 17546.7
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
30 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 17546.7
Subtracting 0 from 0 leaves us 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.

After the division, we end up with 17546.7 and a remainder of 0.0.
