887636 ÷ 30 
The aim is to understand the frequency of 30 in 887636.

Moving on to step 1:
If we divide 8 by 30, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 30

On to step 2:
30 can be fit into 88 2 times, resulting in a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 60 from 88 and we're left with 28.
Grab the next digit (7) from the dividend, add it to 28, then carry on: 287 / 30

Moving on to step 3:
If we divide 287 by 30, we get 9 and a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 29.0
If we take 270 away from 287, we end up with 17.
Append the next digit (6) from the dividend to 17 and continue with: 176 / 30

Going ahead to step 4:
30 goes into 176 5 times with a remainder of 26.
Use 5 as the next digit of our solution. 
Result so far: 295.0
Subtract 150 from 176 to get 26.
Fetch the next digit (3) from the dividend, attach it to 26 and continue: 263 / 30

Advancing to step 5:
If we divide 263 by 30, we get 8 and a remainder of 23.
Write down 8 as next digit of the result. 
Result so far: 2958.0
If we subtract 240 from 263, we get 23.
Append the next digit (6) from the dividend to 23 and continue with: 236 / 30

Let's proceed to step 6:
If we divide 236 by 30, we get 7 and a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 29587.0
If we take 210 away from 236, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 7:
The number 30 fits into 260 8 times, leaving a remainder of 20.
The next digit of our result is 8. 
Result so far: 29587.8
Subtract 240 from 260 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:
200 divided by 30 is 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 29587.86
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.

Advancing to step 9:
30 goes into 200 6 times with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 29587.866
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.

The final outcome is 29587.866, with a leftover of 0.002.
