We look at the division of 910663 by 30 
The aim is to understand the frequency of 30 in 910663.

Moving on to step 1:
If we divide 9 by 30, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 30

Moving on to step 2:
When dividing 91 by 30, we get 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 1 after subtracting 90 from 91.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 30

Advancing to step 3:
The number 30 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
The remainder is 10 after subtracting 0 from 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 30

Moving on to step 4:
30 can be fit into 106 3 times, resulting in a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 303.0
If we subtract 90 from 106, we get 16.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 30

On to step 5:
The number 30 fits into 166 5 times, leaving a remainder of 16.
Use 5 as the next digit of our solution. 
Result so far: 3035.0
If we take 150 away from 166, we end up with 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 30

Let's proceed to step 6:
163 divided by 30 is 5 with a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 30355.0
Deduct 150 from 163 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
When dividing 130 by 30, we get 4 with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 30355.4
Subtracting 120 from 130 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.

Advancing to step 8:
The number 30 fits into 100 3 times, leaving a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 30355.43
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
30 can be fit into 100 3 times, resulting in a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 30355.433
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.

The final outcome is 30355.433, with a leftover of 0.001.
