696569 ÷ 30 
The aim is to understand the frequency of 30 in 696569.

On to step 1:
When dividing 6 by 30, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 30

Advancing to step 2:
If we divide 69 by 30, we get 2 and a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 60 away from 69, we end up with 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 30

Moving on to step 3:
30 goes into 96 3 times with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we subtract 90 from 96, we get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 30

Going ahead to step 4:
30 goes into 65 2 times with a remainder of 5.
The next digit of our result is 2. 
Result so far: 232.0
The remainder is 5 after subtracting 60 from 65.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 30

Advancing to step 5:
56 divided by 30 is 1 with a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 2321.0
The remainder is 26 after subtracting 30 from 56.
Bring next digit (9) of the dividend behind the 26 and repeat the process: 269 / 30

Step 6:
30 can be fit into 269 8 times, resulting in a remainder of 29.
Use 8 as the next digit of our solution. 
Result so far: 23218.0
The remainder is 29 after subtracting 240 from 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 7:
30 can be fit into 290 9 times, resulting in a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 23218.9
Subtract 270 from 290 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 23218.96
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
30 can be fit into 200 6 times, resulting in a remainder of 20.
The next digit of our result is 6. 
Result so far: 23218.966
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 23218.966 and a remainder of 0.002.
