859595 divided by 30 
The aim is to understand the frequency of 30 in 859595.

Advancing to step 1:
The number 30 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 30

On to step 2:
If we divide 85 by 30, we get 2 and a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 60 from 85, we get 25.
Append the next digit (9) from the dividend to 25 and continue with: 259 / 30

Moving on to step 3:
When dividing 259 by 30, we get 8 with a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we take 240 away from 259, we end up with 19.
Append the next digit (5) from the dividend to 19 and continue with: 195 / 30

Let's proceed to step 4:
30 can be fit into 195 6 times, resulting in a remainder of 15.
The next digit of our result is 6. 
Result so far: 286.0
If we take 180 away from 195, we end up with 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 30

On to step 5:
30 can be fit into 159 5 times, resulting in a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 2865.0
The remainder is 9 after subtracting 150 from 159.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 30

Going ahead to step 6:
95 divided by 30 is 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 28653.0
Subtracting 90 from 95 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
If we divide 50 by 30, we get 1 and a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 28653.1
The remainder is 20 after subtracting 30 from 50.
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 8:
30 goes into 200 6 times with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 28653.16
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.

Let's proceed to step 9:
If we divide 200 by 30, we get 6 and a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 28653.166
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.

The final outcome is 28653.166, with a leftover of 0.002.
