919087 divided by 30 
The aim is to understand the frequency of 30 in 919087.

Let's proceed to step 1:
30 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 30

Advancing to step 2:
30 can be fit into 91 3 times, resulting in a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 90 away from 91, we end up with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 30

Let's proceed to step 3:
The number 30 fits into 19 0 times, leaving a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 30.0
If we take 0 away from 19, we end up with 19.
Include the next digit (0) from the dividend after 19, then repeat: 190 / 30

Moving on to step 4:
30 can be fit into 190 6 times, resulting in a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 306.0
Subtract 180 from 190 to get 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 30

Moving on to step 5:
When dividing 108 by 30, we get 3 with a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 3063.0
The remainder is 18 after subtracting 90 from 108.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 30

Moving on to step 6:
30 goes into 187 6 times with a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 30636.0
Deduct 180 from 187 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
If we divide 70 by 30, we get 2 and a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 30636.2
Subtracting 60 from 70 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
When dividing 100 by 30, we get 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 30636.23
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
If we divide 100 by 30, we get 3 and a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 30636.233
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 30636.233, with a leftover of 0.001.
