We're dividing 891207 by 30 
The aim is to understand the frequency of 30 in 891207.

Going ahead to step 1:
The number 30 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 30

Let's proceed to step 2:
When dividing 89 by 30, we get 2 with a remainder of 29.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 60 from 89 and we're left with 29.
Bring next digit (1) of the dividend behind the 29 and repeat the process: 291 / 30

Advancing to step 3:
291 divided by 30 is 9 with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
If we take 270 away from 291, we end up with 21.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 30

Let's proceed to step 4:
The number 30 fits into 212 7 times, leaving a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 297.0
If we subtract 210 from 212, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 30

Going ahead to step 5:
If we divide 20 by 30, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 2970.0
If we take 0 away from 20, we end up with 20.
Bring next digit (7) of the dividend behind the 20 and repeat the process: 207 / 30

Step 6:
If we divide 207 by 30, we get 6 and a remainder of 27.
The number 6 becomes the next digit in our result. 
Result so far: 29706.0
If we take 180 away from 207, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 7:
The number 30 fits into 270 9 times, leaving a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 29706.9
Deduct 270 from 270 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.

Moving on to step 8:
When dividing 0 by 30, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 29706.9
If we take 0 away from 0, 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.

Advancing to step 9:
0 divided by 30 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 29706.9
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 29706.9 and a remainder of 0.0.
