We're dividing 74686164 by 30 
The aim is to understand the frequency of 30 in 74686164.

Let's proceed to step 1:
30 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 30

Moving on to step 2:
When dividing 74 by 30, we get 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 60 from 74, we get 14.
Include the next digit (6) from the dividend after 14, then repeat: 146 / 30

Going ahead to step 3:
146 divided by 30 is 4 with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we subtract 120 from 146, we get 26.
Take the next digit (8) from the dividend and append it to 26, then repeat: 268 / 30

Let's proceed to step 4:
30 can be fit into 268 8 times, resulting in a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 248.0
Subtracting 240 from 268 leaves us with 28.
Bring next digit (6) of the dividend behind the 28 and repeat the process: 286 / 30

On to step 5:
If we divide 286 by 30, we get 9 and a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 2489.0
Subtract 270 from 286 to get 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 30

Advancing to step 6:
30 goes into 161 5 times with a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 24895.0
Deduct 150 from 161 and we're left with 11.
Append the next digit (6) from the dividend to 11 and continue with: 116 / 30

Let's proceed to step 7:
116 divided by 30 is 3 with a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 248953.0
If we subtract 90 from 116, we get 26.
Include the next digit (4) from the dividend after 26, then repeat: 264 / 30

On to step 8:
If we divide 264 by 30, we get 8 and a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 2489538.0
The remainder is 24 after subtracting 240 from 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
If we divide 240 by 30, we get 8 and a remainder of 0.
The next digit of our result is 8. 
Result so far: 2489538.8
Subtract 240 from 240 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.

Moving on to step 10:
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: 2489538.8
The remainder is 0 after subtracting 0 from 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 11:
When dividing 0 by 30, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2489538.8
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 2489538.8 and a remainder of 0.0.
