850887 ÷ 30 
The aim is to understand the frequency of 30 in 850887.

On to step 1:
30 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 30

Moving 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
Subtract 60 from 85 to get 25.
Fetch the next digit (0) from the dividend, attach it to 25 and continue: 250 / 30

Going ahead to step 3:
250 divided by 30 is 8 with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Subtracting 240 from 250 leaves us with 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 30

Step 4:
When dividing 108 by 30, we get 3 with a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 283.0
If we subtract 90 from 108, we get 18.
Fetch the next digit (8) from the dividend, attach it to 18 and continue: 188 / 30

Advancing to step 5:
If we divide 188 by 30, we get 6 and a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 2836.0
Deduct 180 from 188 and we're left with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 30

On to step 6:
87 divided by 30 is 2 with a remainder of 27.
Record the quotient 2 as the next digit in the result. 
Result so far: 28362.0
If we subtract 60 from 87, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On 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: 28362.9
If we take 270 away from 270, 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.

On to step 8:
0 divided by 30 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 28362.9
Deduct 0 from 0 and we're left 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.

On to step 9:
If we divide 0 by 30, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 28362.9
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.

In conclusion, the division gives 28362.9 with a balance of 0.0.
